How to install lower sliders on 2008 ultra classic


Loosen the fork cap bolt from the fork tube plug at the top of the fork tube, but do not remove it at this time. THEN loosen the pinch bolt (with lockwasher) in the lower fork bracket, but do not remove it. THEN spray glass cleaner like Windex on the fork tube above the rubber fork stop and after so lubricating the surfaces move the fork stop up the fork tube until it contacts the bottom of the upper fork bracket. THEN, while holding the fork slider to prevent the fork from dropping, remove the fork cap bolt from the fork tube plug and slide the fork tube down and out of the upper fork bracket, the fork stop, the lower fork bracket, and the slider cover. THEN thread the fork cap bolt back into the fork tube plug to prevent loss of fork oil while handling the removed fork assembly. THEN move the fork to your work bench area and place a suitable drain pan on the floor underneath your vise. NOW or later you can similarly remove the other fork tube assembly.

IT IS HANDY to have a HD-41177 FORK TUBE HOLDER or similar tool.

On the first fork remove the nuts, the lockwashers, the flat washer and the axle holder from the studs at the end of the fork slider. THEN clamp end of a fork holder tool in your vise in a horizontal position with the tightening fasteners facing toward you and with the fork cap bolt at the top clamp the fork tube in between the rubber pads on the inside of the tool and tighten the fasteners to securely hold the fork tube assembly. THEN remove the fork cap bolt from the fork tube plug and remove and throw away the quad ring seal. Thenslowly unthread the fork tube plug from the fork tube being AWARE that the fork tube plug is under spring pressure which requires you to have a firm grasp on plug as the last thread is turned. THEN remove the O-ring from fork tube plug and throw it away. THEN remove the fork spring from the fork tube and remove the fork assembly from the fork tube holder. THEN turn the fork upside down and drain the fork oil into the drain pan by slowly pumping the fork tube and slider at least ten times being aware that the damper valve, if it has one, may fall out of the inverted fork tube while you are draining it. THEN With the wear ring at the bottom, i.e. with the spring side up, slide the damper valve back into the fork tube when it has been fully drained.

THEN for further disassembly install the fork spring back into the fork tube place a shop rag on the floor, and turn the fork assembly upside down and press the end of spring against the rag. Push down and compress the spring to prevent the damper tube from turning and then remove the6mm screw from end of fork slider with a strong short stroke impact wrench and 12 mm Allen socket adapter for best results. When the screw and washer are removed throw away the 6mm screw and copper crush washer. THEN remove the fork spring, the damper valve (if it has one) and the damper tube from fork tube. THEN remove the wear ring and the rebound spring from the damper tube and it has one, from the damper valve, if it has one. Then without expanding or stretching the retaining clip to avoid it becoming bent or distorted, remove it from the fork tube. THEN, using an appropriate pick tool, remove the retaining clip from between the fork slider and the fork tube and remove the fork tube from the fork slider. Use the fork tube as a slide hammerwith a moderate amount of force until the fork tube separates from the fork slider. THEN slide the fork oil seal, the slider spacer and the slider bushing off of the end of the fork tube and throw away the fork oil seal and the slider bushing. THEN gently pry at the split line to expand the fork leg bushing, and remove it from the groove at the end of the fork tube and throw away the fork leg bushing. THEN remove the lower stop fromthe fork slider.

THEN thoroughly clean and inspect all of the parts. And replace all parts that are bent, broken or otherwise obviously damaged. Inspect the fork cap bolt quad ring seal and the fork tube plug O-ring for cuts, tears or other signs of deterioration and replace whatever is necessary and/or prudent. THEN replace the retaining clip if bent or distorted and check the slider and fork leg bushings for scratches or excessive wear and always replace bushings in a set if either bushing is damaged or worn THEN also check the fork tube and the slider for scoring, scratches and excessive or abnormal wear and replace all parts as necessary and/or prudent. THEN set the fork tube on V-blocks and measure the runout using a dial indicator gauge and replace the fork if runout exceeds 0.008 in. (0.2 mm). THEN inspect the upper fork spring and the rebound spring for damage or distortion and replace the upper fork spring if the free length is less than 18.4 in. (467.3 mm) and replace the rebound spring if its free length is less than 0.938 in. (23.8 mm) or otherwise whenever the upper fork spring requires replacement.
To reassemble the fork coat the fork leg bushing ID with clean fork oil and then expand the fork leg bushing at the split line only so far as required to it slip over the end and into the groove of the fork tube. THEN install a new wear ring in the groove at the top of the damper tube and install the rebound spring on the opposite end. Now, with the wear ring on the top side slide the damper tube into the fork tube, so that the tube end drops through the hole at the bottom of the fork tube. Now install the lower stop at the end of the damper tube and put the fork slider back into your fork tube holder. THEN slide the fork tube into the fork slider. NEXT coat the slider bushing ID with clean fork oil and install the slider bushing down into the fork tube and then slide the slider spacer down the fork tube until it meets the slider bushing and then get your fork oil seal installer tool and it down the fork tube and drive the slider bushing and spacer into the bore of the fork slider and then remove the tool and THEN put some masking tape over the top edge of the fork tube to avoid damaging the lip of the fork oil seal during installation and then coat the new oil seal with new fork oil and install the seal with the garter spring facing into the fork tube and slide it down to the bore of the slider and the earlier installed spacer and then remove the masking tape and with your fork seal installation tool drive the seal down into the top of the slider until you can insert the retaining ring and then again remove the seal driver tool and install the retainer ring into its slider groove. NOW slide the fork spring into the tube and remove the fork assembly from your fork tube holder and with a shop towel or rag on the floor turn the assembly upside down and press the spring against the shop towel or rag and install a new 6mm screw with a new copper crush washer through hole at bottom of fork slider and start to screw it into the end of the damper tube. Continue to compress the spring into the assembly to stop the damper tube from turning and tighten the 6mm screw to 132-216 in-lbs (14.9-24.4 Nm). After this remove the fork spring from the fork tube and again clamp the fork slider (NOT THE FORK TUBE) into your fork holder tool with the fork tube on the top side and if it was previously removed install the drain plug at the bottom of the fork slider and tighten it to 72-96 in-lbs (8-11 Nm).

THEN refill with the correct amount of fork oil. It is very important for the correct and safe operation of the bike that the CORRECT amount of oil be installed. FOLLOW the correct procedures for doing this.

2009 harley street bob fork seal replacement


I have never seen seals replaced without dismantling the forks. The seal will come in a fork revbuild kit whether the bushings etc are used or not. Obtained separately but necessary in any case are new lower fork bolts and copper washers. I suppose it might be possible to get the seal out of the fork leg without completely dismantling the fork but the normal way of removing the seal is to use the slider as a slider hammer tool to drive the upper bushing and seal from the fork leg which requires removal of the lower bolt and washer and pretty much fully dismantling the fork. You will also need a special fork holder tool or at the least a pair of vise soft jaws and it is critical how much fork oil is added back into the fork as too much will make the ride unacceptably hard and too little will allow the fork to compress too much and be too soft. You also really need an appropriate seal installer to reinstall the seal and upper bushing etc. All that being said:

How do i rebuild 41mm forks


Depends on how much rebuilding you want to do.
See below:

FRONT FORK 2.16
CHANGING FORK OIL On a 2010 Touring Motorcycle 41 mm Fork
If only replacing the fork oil remove the for, clamp a fork holder tool in a vise in a horizontal position and with the fork cap bolt topside securely clamp the fork into the tool, remove the fork cap bolt, remove and discard the quad ring seal, carefully remove the fork tube plug from the fork tube and because it is under strong spring pressure have and maintain a firm grasp on the plug as the last thread is turned because it will want to fly upwards under the spring pressure, remove and discard the O-ring fork tube plug o-ring, remove the fork spring from the fork tube, remove the fork assembly from the fork tube holder tool, being aware that the damper valve if one is installed (All touring models, with the exception of Road King, have a damper valve type fork on both the left and right sides. Road King uses the conventional type fork on both sides.) will fall out when the fork tube is inverted for draining turn the fork upside down and drain the fork oil into a suitable drain pan while slowly pumping the fork tube and slider at least ten times and then allow about 10-15 minutes for the fork assembly to completely drain. THEN with the fork tube right-side-up securely clamp the fork slider (not the fork tube) into the fork tube holder, install the drain plug at the bottom of the fork slider, if it had been removed and tighten the plug to 72-96 in-lbs (8-11 Nm).

MODEL FORK TYPE AMOUNT
OZ. ML IN. MM
All models Damper Valve 10.7 317 4.92 125
Except FLHR/C
FLHR/C Conventional 11.0 325 4.92 125

Pour slightly more Harley-Davidson Type E Fork Oil directly into the fork tube than is specified for the fork type, slowly pump the fork tube until some resistance is felt and then pump a few more times and then for all models except FLHR/C (i.e. for damper valve type forks), install a new wear ring in its groove in the damper valve, with the wear ring at the bottom (spring side up) slide the damper valve into the fork tube, install the fork spring into the fork tube, use the fork spring to push the damper valve to the bottom of the fork tube, remove the fork spring from the fork tube, slowly pump the fork tube a few more times to eliminate air from the damper valve, adjust the ring of a fork level gauge 4.92 inches or 125mm and then with the fork tube bottomed in the fork slider insert the tube of the gauge into the fork slider until the metal ring rests flat on the top of the fork tube and use the gauge plunger to draw oil from fork (if no oil is drawn out, add a small amount to the fork tube and repeat the process) until the oil level is at the specified level in the fork slider, install the fork spring into the fork tube with the tighter wound coils at the bottom, remove the fork slider from the fork tube holder tool, clamp fork tube into the fork tube holder tool, install a newO-ring onto the fork tube plug, install the fork tube plug into the fork tube and tighten it to 60-70 ft-lbs (81.4-94.9 Nm), install a newquad ring seal onto the fork cap bolt and install it into the fork tube plug to prevent loss of fork oil while working further with it. THEN on right side fork, loosely install the axle holder with its flat
washers, lockwashers and nuts, install the fork and assemble the motorcycle.

To remove a 2010 Touring 41 mm fork assembly FIRSTraise the front wheel, remove the front wheel, remove the front fender, and for FLHR/C remove the headlamp nacelle. And for FLHX, FLHT/C/U, FLHTK remove inner fairing cap, and for FLTRX remove the instrument nacelle, loosen the fork cap bolt, but do not
remove it at this time, loosen the pinch bolt but do not remove it, hold the fork slider to prevent the fork from dropping, remove the fork cap bolt from the fork tube plug, slide the fork tube down to remove. And loosely install the fork cap bolt to prevent loss of fork oil while working with the fork.

DISASSEMBLY
To disassemble a 2010 Touring 41mm fork assembly FIRST remove the fork assembly, the right side fork remove the axle holder from the end of the fork slider, drain the fork, install the fork spring into the fork tube, place a shop cloth or towel on the floor, turn the fork assembly upside down, press the end of the spring against the shop cloth or towel to prevent rotation of the damper tube and remove the metric screw from the end of the fork slider with an air impact wrench, discard the screw and copper washer, remove the fork spring, the damper valve (if equipped) and the damper tube from the fork tube, remove the wear ring and rebound spring from the damper tube, remove the wear ring from the damper valve, (if equipped), remove the retaining clip using an appropriate pick tool, remove the fork tube from the fork slider by using the fork tube as a slide hammer tool, slide the fork oil seal, the slider spacer and the slider bushing off from the end of the fork tube, discard the fork oil seal and the slider bushing, gently pry at the split line to expand the fork leg bushing and remove it from its groove at the end of the fork tube, discard the fork leg bushing and remove the lower stop from fork the slider.

CLEANING AND INSPECTION
Thoroughly clean and inspect all parts and replace any parts that are corroded, bent, inoperative or otherwise obviously damaged, inspect the fork cap bolt quad ring seal and the fork tube plug o-ring for cuts, tears or signs of deterioration and replace if and as necessary, replace the retaining clip if is bent or distorted, check the slider and the fork leg bushings for scratches or excessive wear and always replace bushings in a set if either bushing needs to be replaced, check both the fork tube and the fork slider for scoring, scratches and excessive or abnormal wear and replace parts if and as required, set the fork tube on V-blocks and measure its runout using a dial indicator gauge and replace it if the runout exceeds 0.008 in. (0.2 mm), inspect the upper fork spring and the rebound spring for damage or distortion, and replace the upper fork spring if its free length is less than19.27 in. (489.4 mm) for Non-Fairing Models and 18.73 in. (475.7 mm) for Fairing Models and replace the rebound spring if its free length is less than 0.938 in. (23.8 mm) or any time the upper fork spring is replaced.

ASSEMBLY
To assemble a 2010 Touring 41 mm fork assembly FIRST coat the ID of the fork leg bushing with clean fork oil, expand the fork leg bushing at the split line only enough to slip it over the end of the fork tube and into its groove on the fork tube, install a newwear ring into the groove at the top of the damper tube, install the rebound spring on the opposite end, with the wear ring topside slide the damper tube into the fork tube so that the tube end drops through the hole at the bottom of the fork tube, install the lower stop at the end of the damper tube, install the fork slider into the fork tube holder tool, slide the fork tube into the fork slider, coat the ID of the slider bushing with clean fork oil, slide the slider bushing down the fork tube, slide a 41 mm fork seal installer tool down the fork tube and using the it as a slide hammer drive the slider bushing into the counterbore of the fork slider, then remove the tool, place masking tape over edge of the fork tube to avoid damaging the lip of the fork oil seal during installation, coat the ID ofa new fork oil seal with clean new fork oil, then with the lip garter spring side facing down toward the fork slider slide the seal down the fork tube until it contacts the slider spacer, remove the masking tape from the edge of the fork tube and using the 41 mm fork seal installer tool as a slide hammer, drive the fork oil seal down the fork tube until the retaining clip groove is visible above the seal in the ID of the fork slider, remove the tool, install the retaining clip in the groove, install the fork spring into fork the fork tube, remove the fork assembly from the fork tube holder tool, place a shop cloth or towel on the floor, turn the fork assembly upside down and press the end of the spring against the shop cloth or towel to prevent rotation of the damper tube, install a new screw and a new copper washer at the bottom of the fork slider and while compressing the spring tighten the screw to 132-216 in lbs(14.9-24.4 Nm), remove the fork spring from the fork tube, fill the fork with fork oil to the specified amount and complete assembly of the fork. On the right side fork, loosely install the axle holder with its flat
washers, lockwashers and nuts.

INSTALLATION
To install a 2010 Touring 41 mm fork assembly FIRST remove the fork cap bolt, slide the fork tube up and into the slider cover, lower the fork bracket, the fork stop, and the upper fork bracket, install the fork cap bolt, install the pinch bolt and lockwasher into the lower fork bracket and tighten the pinch bolt to 53-57 ft-lbs(71.9-77.3 Nm), tighten the fork cap bolt to 60-70 ft-lbs (81.4-94.9 Nm) and repeat these steps on the other fork, install the front fender and wheel, and for FLHR/C install the headlamp nacelle, for FLHX, FLHT/C/U, FLHTK install the fairing inner cap and for FLTRX install the instrument nacelle.

Is there a thunderbird 1600 steering damper?


Has it always done this ? Have you checked the bearings , tyre condition , fork seals , fork air pressures balanced etc ? Have you changed the make of tyre ? Check the Rear end also as it can transpher ! You can buy any damper and make it fit as long as the travel is enough and make clamps !

I have no diagrams for you. MAke your own as you take it apart etc and take lots of cell phone pictures if you need help remembering how to put things back together.

Table 1-6. Type E Fork Oil Amounts



MODEL OZ CC IN. MM



FXDXT 11.5 341 6.10 154.9



FXDWG 12.0 356 7.28 184.9



FXDL 10.7 316 7.20 182.9



FXD 10.6 314 6.69 169.9




Changing fork oil is a simple mater for some models and requires fork disassembly for others. Here is the procedure for all 2001 DYNA models:

2001 DYNA FRONT FORK OIL 1.18


REPLACING FORK OIL Replace front fork oil at every 20,000 mile (32,000 km) service interval and/or prior to storage.


ALL BUT FXDX & FXDXT models


Raise and support the motorcycle so the front end is off the floor and the forks are fully extended, on FXDL models, remove the center plug from each fork cap, on all other models, remove the fork tube caps, remove the drain screws from the bottom of each fork and drain the fork oil, replace the drain screws and washers and tighten the screws

to 13-17 in-lbs (1.5-2.0 Nm) THEN see Table 1-6. and fill the fork with Harley-Davidson TYPE E FORK OIL (Part No. HD-99884-80) as set out in the Table. THEN if apart assemble the forks as follows:


a. FXD, FXDXT, FXDWG models: install both fork tube caps and tighten them to 11-22 ft-lbs (14.9-29.8 Nm).

b. FXDL models: install center plugs and tighten until secure.


Fork oil amounts can be measured two ways: use the oz./cc measurement if fork is left in frame; use the in./mm measurement if the fork is disassembled in which case the oil level is measured from the top of the fork tube with the spring removed and the fork fully compressed.

FRONT FORKS: FXDX & FXDXT 2.20

REMOVAL

Raise and support the motorcycle so the front end is off the floor and the forks are fully extended, remove both front brake calipers and the front wheel, remove the front fender, remove the front fairing, remove the headlamp bracket and attach the headlamp to the frame using a rubber bungee strap, loosen the upper and lower triple clamp pinch bolts and pull the fork sides from the brackets.


DISASSEMBLY

Remove the stopper ring, remove the spring preload adjuster but DO NOT unthread the rebound adjuster from the damper rod because incorrect assembly could result in reduced adjustment range. THEN unthread the fork cap from the fork tube and allow the fork leg to drop, exposing the spring, THEN get a FORK SPRING COMPRESSION TOOL (Part No. HD-41549A) on the spring collar, turn the screws in to engage the holes in collar, compress the spring until the SPRING PLATE TOOL (Part No. HD-

41551) can be positioned between the spacer and the spring collar, THEN hold the fork bolt and compression adjuster, remove the fork bolt from the compression adjuster, remove the spring adjuster plate from the fork bolt, remove spacer, spring collar and spring, pour out the fork oil by pumping the fork leg and rod 8-10 times or until rod the moves freely. THEN position fork slider in vise using a FORK TUBE HOLDER such as (Part No. HD-41177) to avoid damage. THEN remove the socket head bolt, remove the damper from the fork tube, remove the cover from the slider, remove seal and stopper ring, pull the fork tube out of the slider, remove the oil seal, spacer and guide bushing from the fork tube.


CLEANING AND INSPECTION

Measure the fork spring free length and replace the spring if it is shorter than 17.00 in. (431.8 mm), check the fork tube and the slider for score marks, scratches or abnormal wear, check the slide and guide bushings for excessive wear or scratches, set the fork tube on V-blocks and measure runout which should not exceed 0.008 in. (0.2 mm).


ASSEMBLY

Coat the oil seal with TYPE E FORK OIL, before installing the slide bushing and guide bushing, lubricate them with fork oil, THEN install the guide bushing and the spacer seal noting that the guide bushing opening must be oriented to the side and NOT to the front or rear, THEN slip the slider into the fork tube, place the slide bushing over the fork tube until it rests on the slider, drive the guide bushing with the spacer seal into the slider, lubricate a new oil seal with TYPE E FORK Oil, drive the oil seal into the slider using FORK SEAL INSTALLER (Part No. HD-36583). install the stopper ring and dust seal, (if the rebound adjuster was removed from the damper rod bottom the lock nut on the threaded portion of damper rod, holding a thumb on the detent spring and ball, back out (turn counterclockwise) the rebound adjuster to the last "click." and then turn down (clockwise) 17 "clicks", thread the rebound adjuster onto the damper rod until the adjuster stops at maximum thread engagement (but do not force it), thread the locknut onto the damper rod up until it contacts the base of the rebound adjuster and tighten it in place), THEN holding the slider in a vise while being careful not to damage it. install the damper tube into the fork tube and tighten the socket screw and washer to 22-29 ft-lbs (29.8-39.3 Nm). THEN pour half the TYPE E FORK OIL into the fork tube, slowly pump the damper rod 10 or more times, position the damper rod in the fully bottomed position and pour the remaining amount of TYPE E FORK OIL into the fork tube. THEN using a PRO-LEVEL OIL GAUGE (Part No. HD-59000A) or similar adjust the oil level to 5.04 in. (128 mm). THEN carefully clean and install the spring, the spring collar, and the spacers with the sharp edge created when they were stamped out when manufactured, facing the collar. THEN using a FORK SPRING COMPRESSION TOOL such as (Part No. HD-41549A) push spring collar down and place a SPRING PLATE such as (Part No. HD-41551) between the spacer and the spring collar, install the fork cap and tighten it against the rebound adjuster to 22-29 ft-lbs (29.8-39.3 Nm). THEN tighten the fork cap onto the fork tube to 11-22 ft-lbs (14.9-29.8 Nm), install the spring adjuster plate, replace the O-rings on the spring preload adjuster and lubricate them with fork oil. THEN install the spring preload adjuster and the stopper ring and carefully drive the slider cover into the slider.


INSTALLATION

Insert both fork side assemblies up through the fork stem and bracket and upper bracket and tighten the fork stem bracket pinch bolt(s) to 30-35 ft-lbs (40.7-47.5 Nm). Then re-install the headlamp bracket, install the front fender, install the front wheel and the brake caliper When the motorcycle is again ready for the road adjust the headlamp and road test the motorcycle.

How do I reassemble front forks of bike


Refer to this site, www.bikebandit.com for an exploded view of the front forks. Basically you must have the seals in the slider (lower part) and the damper tube in the upper fork tube. Then slide the upper fork tube down into the lower and install the bolt in very end of the slider. Then install the spring and top plug or put it in the triple trees and intstall the top cap. You'll have to put the appropiate amount of the correct weight oil in the tubes. The amount depends on what kind of forks they are. Since they've been taken apart, use the "dry" (as compared to 'wet") amount of oil.

Good Luck

Coat the oil seal with TYPE E FORK OIL, before installing the slide bushing and guide bushing, lubricate them with fork oil, THEN install the guide bushing and the spacer seal noting that the guide bushing opening must be oriented to the side and NOT to the front or rear, THEN slip the slider into the fork tube, place the slide bushing over the fork tube until it rests on the slider, drive the guide bushing with the spacer seal into the slider, lubricate a new oil seal with TYPE E FORK Oil, drive the oil seal into the slider using FORK SEAL INSTALLER (Part No. HD-36583). install the stopper ring and dust seal, (if the rebound adjuster was removed from the damper rod bottom the lock nut on the threaded portion of damper rod, holding a thumb on the detent spring and ball, back out (turn counterclockwise) the rebound adjuster to the last "click." and then turn down (clockwise) 17 "clicks", thread the rebound adjuster onto the damper rod until the adjuster stops at maximum thread engagement (but do not force it), thread the locknut onto the damper rod up until it contacts the base of the rebound adjuster and tighten it in place), THEN holding the slider in a vise while being careful not to damage it. install the damper tube into the fork tube and tighten the socket screw and washer to 22-29 ft-lbs (29.8-39.3 Nm). THEN pour half the TYPE E FORK OIL into the fork tube, slowly pump the damper rod 10 or more times, position the damper rod in the fully bottomed position and pour the remaining amount of TYPE E FORK OIL into the fork tube. THEN using a PRO-LEVEL OIL GAUGE (Part No. HD-59000A) or similar adjust the oil level to 5.04 in. (128 mm). THEN carefully clean and install the spring, the spring collar, and the spacers with the sharp edge created when they were stamped out when manufactured, facing the collar. THEN using a FORK SPRING COMPRESSION TOOL such as (Part No. HD-41549A) push spring collar down and place a SPRING PLATE such as (Part No. HD-41551) between the spacer and the spring collar, install the fork cap and tighten it against the rebound adjuster to 22-29 ft-lbs (29.8-39.3 Nm). THEN tighten the fork cap onto the fork tube to 11-22 ft-lbs (14.9-29.8 Nm), install the spring adjuster plate, replace the O-rings on the spring preload adjuster and lubricate them with fork oil. THEN install the spring preload adjuster and the stopper ring and carefully drive the slider cover into the slider.

Front forks will not seal


dissassemble forks and replace fork seals.(and oil) becareful forks are under a lot of spring pressue. use a workbench vise to hold fork tubes. you will need the manual for this. plus you will need to know the "proper" amount of fluid to put back into the forks.

Is decarbonising is necessary


Hi! With modern fuels and oils there really shouldn't be any need to de-carbonise.(Unlees Mixture is incorrect?) If you are really concerned then try a quality fuel additive, read fully the directions for use and Bingo job's a good-un.
Fork oil change, is there a reason? are the forks weak? any seapage? if not leave well alone as you may open a Hornets Nest.
Telescopic forks/dampers use very light oil for suspension, too much will blow oil seals, so if you are determined to change the fluid then make sure the correct viscosity is used and critically the correct amount/quantity. Cleanliness is of the utmost!
Good Luck!
