12Nm is common for 6x100mm with 8mm head screws.If the head of the screw is 10mm I recommend 14Nm.

1988 FLHTC E-Glide. What is the torque spec for the 4 bolts holding the clutch assembly (diaphragm spring, friction and steel plates) to the clutch basket??


Hi Thomas, it's 8 ft lbs. but there are three different settings on the clutch adjustment plate. Since you have an old bike try the "B" setting first, the end result you are looking for is the pressure plate to be as flat as possible not convex or concave. Tighten bolts in a criss cross pattern in increments. I am extremely knowledgeable and experienced on this old stuff if you have any other questions contact me at: xlch@mail.com and good luck.

What are the tightening torques of all clutch plate pressure plate flywheel bolts of 2279cc slant engine vauxhalls


I have some original manuals for the model somewhere and the Kent-Moore service tool for adjusting the valve clearances. There isn't much information in my general data book but the flywheel bolts are 66 Nm.

The clutch cover bolts do have a torque value but I don't have it to hand and have never used it or heard of anyone using it. Good sense will suffice.
The important thing is to tighten the cover bolts a little at a time evenly until tension is felt and then it is sufficient to "knip" them a little further. There should be a spring washer under each cover bolt head and it is important they and the bolts are all identical

HOW DO I CHANGE MY CLUTCH AND PLATES 2008 FLHTCU?


Clutch and plates replacement can be performed on the motorcycle without removing the clutch shell or hub.


FIRST remove the primary chaincase cover. THEN remove six metric bolts to release the clutch diaphragm spring retainer from the clutch hub by loosening each bolt gradually and in a star sequence around the Hub circumference and then remove the diaphragm spring retainer, the diaphragm spring and pressure plate from the clutch hub and after the pressure plate has been removed remove the 9 friction plates, the steel plates, the damper spring and the damper spring seat from the clutch hub. Clean and inspect as necessary and wash all parts except for friction plates (and any bearing if removed) in appropriate cleaning solvent and then blow parts dry with low pressure compressed air as high pressure compressed air is unnecessary and dangerous. CHECK the friction plates by blowing off all lubricant from them BUT DO NOT wipe them off with a rag if they are going to be reused. THEN measure the thickness of each plate with a dial caliper or micrometer and if any plate is less than 0.143 in. (3.62 mm) thick throw them all away and replace them with a complete new set. ALSO look for worn or damaged fiber surface material on all sides. If new friction plates will be installed soak them all in FORMULA+ TRANSMISSION AND PRIMARY CHAINCASE LUBRICANT (or whatever equivalent oil that you will be using in the primary after reassembly) for at least five minutes. THEN CHECK the steel plates for any grooving, bluish colouring (which indicates overheating/burning and which is usually accompanied with distortion/warping) and check for distortion by laying each plate on a machinist or other precision flat surface and try to insert a 0.006 inch (0.15 mm) feeler gauge between the plate and the precision surface. Do this in several places around the plate. If the feeler gauge slips under any plate or any plate is grooved, bluish or otherwise appears to be defective discard it and replace with a new plate. THEN rotate the clutch hub and shell to check for bearing smoothness and replace the bearing if it runs roughly, binds or has any end play. ALSO check the primary chain sprocket and the starter ring gear on the clutch shell at this time and replace the clutch shell if either the sprocket or ring gear are badly worn or damaged. ALSO check the slots that mate with the clutch plates on both the clutch shell and the hub and replace the shell or hub if any of the slots are worn or damaged (wear here can cause clutch hang-up on release). NOW check the diaphragm spring and diaphragm spring retainer for cracks or bent tabs and replace if any damage is evident.


After having soaked the friction plates as advised above first install the narrow friction plate on the clutch hub, engaging the tabs on this plate with the slots in the clutch shell then install the damper spring seat (sometimes called a judder spring) on the clutch hub so that it sits inboard of the previously installed narrow friction plate with the concave side out (facing away from damper spring

seat) (that will be with the narrow side facing into the clutch hub and the wider side facing out) THEN install a steel plate with the round edge (produced when the plate was stamped out from a larger piece of steel) outward and then install a regular friction plate onto the clutch hub and continue by installing the seven remaining sets of steel and fibre plates in the same manner, alternating between steel plates and friction plates so that no two steel are touching each other and so that no two fibre plates are touching each other and then when they are all in place install the pressure plate onto the clutch hub aligning holes in the plate with the threaded bosses on the hub. THEN install and seat the diaphragm spring into the recess of the pressure plate with the concave side inward and with the holes in the diaphragm spring retainer aligned with the threaded bosses on the clutch hub tabs on the spring retainer contact flats on the inboard side of the bosses install the six metric bolts to secure the diaphragm spring retainer to the clutch hub and alternately tighten the bolts to 90-110 in-lbs (10.2-12.4 Nm). THEN install the primary chaincase cover with a new gasket and torque the fasteners to 108-120 in-lbs (12.2-13.6 Nm) in a sequence top to bottom from the centre to the front and then top to bottom from the centre to the back of the cover and then reinstall the primary case drain plug and o-ring and torque it to 14-21 ft-lbs (19.0-28.5 Nm). THEN refill the primary chaincase with lubricant only up to the bottom of the clutch diaphragm spring (if there is too much oil the clutch may drag). THEN adjust the clutch by turning the clutch adjustment screw in until it just resists and then with the cable slack somewhat removed operate the clutch lever a few times to set the clutch release balls in their ramps and then recheck the clutch release pushrod adjustment screw again so that it just resists tightening as it is screwed in and then back it out one half to one full turn and while holding it stationary tighten the adjuster screw lock nut. THEN the cable can be adjusted to provide one sixteenth to one eighth of an inch of freeplay at the clutch cable bracket or perch on the handlebars. THEN reinstall the clutch inspection (derby) cover with the five T-27 Torx screws and washers and alternatively in a cross pattern tighten the screws to 84- 108 in-lbs (9.5-12.2 Nm).

How to set up a new clutch


There is no setting the tension on the springs if the clutch has 4-6 springs as most do. The bolts that hold the clutch springs in tighten all the way down until they are snug (I would say about 100 inch-lbs max for each bolt torque.

Need instructions on how to change my clutch on my 97 roadking


All you have to do is drain and pull the primary cover. Now, I can't remember whether the '97 clutch had the bolts that hold it together or the snap ring. If it has the six bolts holding the clutch spring in, simply take the bolts out and your clutch assembly comes apart. You can change the fiber plates and the spring plate in the middle. If your clutch is held together with a snap ring, you'll need a special tool to disassemble the clutch. You can replace the friction plates, steel plates and the spring plate without taking the entire clutch off the mainshaft with either clutch.

Good Luck
Steve

What is the torque for the bolts that hold the clutch spring plate reduced effort clutch spring on a 2003 FLSTIC msd2455@yahoo.com


I've never really torqued these bolts and I've replaced plenty of the diaphragm springs. Usually I put stronger springs in the clutch since I'm building up the horsepower of the engines. I put a drop of Loctite 242 (med, strength blue) and tighten the bolts to about 25-30 foot pounds. Check the standard torque for a grade five bolt of the size that are in the clutch.
