Every 600 miles or 1000 km. Your motorcycle’s Owner’s Manual will have directions. You need to check the tension at several points along the chain’s travel around the engine and wheel sprockets. The tension should be set so that the loosest spot and the tightest spot are still within the slack tolerance specified in the owner’s manual. If the tightest spot is at the tightest allowed and the loosest is beyond the tolerance then it’s time to get a new chain and sprocket set. ,

SOURCE: chain tension

Most any motorcycle comes with an adjustable chain device on the rear swing arm. as you adjust the small nut inwards towards the front of the bike, it tightens the chain. Likewise for loosening. the adjuster should have increment markings on both sides of the swingarm to even the wheel out. Now I can't say for sure that this is the case with your bike, so I just joined a website that has a forum on these bikes. If you'd like to join as well here is the address http://www.ducati.ms/ I'll get the info from them and relay it back to you. Hope this helps

SOURCE: need to tighten the timing chain

It has an automatic cam chain tensioner. If you are getting cam chain rattle, I would look at worn guides/chain.

SOURCE: Cam chain tensioners

i replaced mine on my cbr f1 with a salvaged one... a couple of bolts and it took me 20 minutes with fairings off. it was a good thing i replaced it, because the old one was worn down really bad, and its was wobbly. I heard that if you use an aftermarket and you don't know what your doing you could cause damage. can i get some feedback, thanks

I can't tighten the chain on my stihl ms 251 chain saw


Pull the side cover and check for a broken or misaligned chain tensioner. I assume that you have loosened the bar nut on the side cover before attempting to adjust the chain tension. The methiod varies depending on whether your model has the side chain tensioner or the quick chain tensioner.

StarTrac NXT Chain Tensioning & Alignment Video


About This Video


Adjusting Chain Tension and Alignment on a StarTrac NXT


  • In this video, we show how to tension and align the chain and flywheel on a StarTrac NXT bike


  • First you see an example of a chain that is way too loose


  • To correct this loosen the flywheel bolt on both sides of the flywheel


  • Loosen the tension nut on the sprocket side of the bike and tighten the tension bolt until you get the proper deflection on the chain



    • A properly tensioned chain will have roughly 3/16" of deflection




  • Tighten the tension nut and the flywheel nut on both sides as shown in the video


Check the Alignment of the Chain and Sprockets after Making a Chain Tension Adjustment


  • Misaligned chains will look like they are walking from side to side where they enter and leave the sprockets



    • This can cause noise, premature wear, as well as making the chain look to be jumping from side to side during use




  • To correct this, loosen the flywheel nut on both sides of the flywheel, then loosen the tension nut and adjust the tension bolt to move the flywheel in the proper direction needed to align the chain with the flywheel sprocket, as seen in the video



    • Note: If you have already achieved proper tension of the chain, adjusting the tension nut on the opposite side from the sprocket will help to keep the same tension on the chain




  • Don't forget to check the chain tension after making an alignment adjustment

Need to put a new chain on a Husqvara 235 14 inch chain saw?


Check that the chain brake is in disengaged position by
moving the front hand guard towards the front handle.
Remove the bar nuts and remove the clutch cover (chain
brake). Take off the transportation ring.
Fit the bar over the bar bolts. Place the bar in its rearmost
position. Place the chain over the drive sprocket locate it in
the groove on the bar. Begin on the top edge of the bar.

Make sure that the edges of the cutting links are facing
forward on the top edge of the bar.
Fit the clutch cover (chain brake) and locate the chain
adjuster pin in the cut-out in the bar. Check that the drive
links of the chain fit correctly on the drive sprocket and that
the chain is in the groove on the bar. Tighten the bar nuts
finger-tight.
Tension the chain by turning the chain tensioning screw
clockwise using the combination spanner. The chain
should be tensioned until it does not sag from the
underside of the bar.
The chain is correctly tensioned when it does not sag from
the underside of the bar, but can still be turned easily by
hand. Hold up the bar tip and tighten the bar nuts with the
combination spanner.
When fitting a new chain, the chain tension has to be
checked frequently until the chain is run-in. Check the
chain tension regularly. A correctly tensioned chain
ensures good cutting performance and long life.

I cannot find my manual to my 18v cordless chainsaw ccs818. I need directions for putting the chain back on. I would like to download a copy of the manual.


Your manual can be found here:

http://www.blackanddecker.com/Manuals.aspx with pop-ups enabled then enter your model number
or
http://www.dewaltservicenet.com/documents/English/Instruction%20Manual/90560838,CCS818.pdf

See the instructions for replacing the chain on page 11. It makes reference to the figures on page 6 so that you know exactly what to remove.

Basically... loosen the bar allen screws. Remove the sprocket cover. Loosen the bar retaining bolts. Use a flat bladed screwdriver on the bar / chain tension screw to shorten the bar enough to install the chain. Then adjust the chain tensioner so that there is just a little slack in the chain at the bottom of bar between the drive sprocket and the bar. Tighten the bar retaining bolts install the cover / tighten all cover fasteners. (see details D and E page 6 of the 2nd link above.)

The steps below are copied from the manual.... I can not undo the formatting and can not post the figures here due to size restrictions..

Thanks for choosing FixYa,

Replacing the Saw Chain

CAUTION: Sharp chain. Always wear protective gloves when

handling the chain. The chain is sharp and can cut you when it is

not running.

WARNING: Sharp moving chain. To prevent accidental

operation, insure that battery is disconnected from the tool

before performing the following operations. Failure to do this

could result in serious personal injury.

• Place the saw on a firm surface. Rotate the two allen head screws

(11) counterclockwise with the wrench (13) provided as shown in

figure E.

• To remove the saw chain (9), rotate the tension adjustment screw

(23) in the front of the housing using the flat screwdriver end of the

wrench (13) as shown in figure F. Turning the screw

counterclockwise allows the guide bar to recede and reduces the

tension on the chain so that it may be removed.

• Remove sprocket cover (10) and allen head screws (11).

• Lift the worn saw chain (9) out of the groove in the guide bar (8).

• Place new chain in groove of guide bar making sure saw teeth are

facing correct direction by matching arrow on chain with graphic on

housing shown in figure G.

• Place the saw chain and guide bar assembly around the sprocket

(19). Check to make sure that the slot (20) in the guide bar (8) is

over the two location pins (21) shown in figure E and that the hole

below the slot is located over the adjustment pin (22).

• Replace sprocket cover (10) and thread allen head screws (11) in

with wrench until snug, then back wrench off one full turn.

• Pull bar nose up and keep it up as you adjust tension.

• Rotate the tension adjustment screw (23) in the front of the housing

clockwise to increase the chain tension as in Figure F.

Follow instructions in "Adjusting Chain Tension" section.

• While still holding the bar nose up, securely tighten the rear allen

screw (11) first, then tighten the front allen screw.

• When the chain is new check the tension frequently (after

disconnecting battery) during the first 2 hours of use as a new chain

stretches slightly.

Adjusting Chain Tension

CAUTION: Sharp chain. Always wear protective gloves when

handling the chain. The chain is sharp and can cut you when it is

not running.

WARNING: Sharp moving chain. To prevent accidental

operation, insure that battery is disconnected from the tool

before performing the following operations. Failure to do this

could result in serious personal injury.

• With the saw still on a firm surface check the chain tension. The
tension is correct when the chain snaps back after being pulled

1/8 inch (3mm) away from the guide bar (8) with light force from the

middle finger and thumb as shown in figure H. There should be no

"sag" between the guide bar and the chain on the underside as

shown in figure I.

• To adjust saw chain tension, loosen the allen head screws (11).

• Rotate the tension adjustment screw (23) in the front of the housing

using the flat screwdriver end of the wrench (13) as shown in

figure F.

• Do not over-tension the chain as this will lead to excessive wear

and will reduce the life of the bar and chain. Overtensioning also

reduces the amount of cuts you will get per battery charge.

• Once chain tension is correct, tighten allen head screws (11).

• When the chain is new check the tension frequently (after

disconnecting battery) during the first 2 hours of use as a new chain
stretches slightly.

I hear a clunking fron the front chain sprocket . I think the chain needs adjusted on my 1995 kawaski zx1100.


Get the rear wheel off the ground and adjust the chain tension. When checking the tension spin the rear wheel and check that the tension does not go slack or get tighter. If the chain is riding up and down the sprocket teeth then the chain is stretched and needs to be replaced. This is the grinding/clunking noise you are hearing. If the sprockets are worn consider a chain and sprocket set, it can be a less expensive option than buying the parts separately.

The chain keeps coming off of my daughters MX500. Is there a way to tighten the chain or the chain tensioner. Is there something else that could be causing it to come off?


The chain usually comes off because it is not tight enough or the chain is not aligned correctly with the sprockets. Check the chain tensioner to see if it is keeping the chain tight and not moving even though it is tight, if it loosens, replace the tensioner. Check the chain for any broken or worn spots or links, if any are found replace the chain.

Tighten chain?


Depending on the model, you adjust the chain tension using the screw that is located either between or below the two nuts that hold the sprocket/bar/chain cover. Loosen the nuts and turn the screw clockwise to tighten, counter-clockwise to loosen. Once you have the tension set, lift up on the bar from underneath and tighten the two nuts. Proper tension should show about half of the chain drive, and should only be done when cold. After 4 to 5 minutes of run time, stop the saw and check the tension again. A little heat in the bar/chain will cause it to loosen up. It will need re-adjusting.

How do I tighten chain on Model Poulan 2050. Can't seem to get tight enough.


Hold the nose up!
c581361.gif Chain Adjustment
  1. Make sure the chain brake is off (gloves will protest your fingers).
  2. If necessary, loosen the bar nuts that are clamping the clutch cover in place (or whatever holds the clutch cover and bar on). They don't need these really loose - finger tight will do.
  3. Ease the tension adjustment until the chain is obviously loose.
  4. Using one hand, hold the nose of the bar up.
  5. While holding the nose up, adjust the tensioner so that the center of the chain just touches the underside of the bar, add a touch more.
  6. Continue holding the nose of the bar up & tighten up the bar nuts / bolts / quick-release system. HTH

My first chainsaw...am seeking general advice on product use etc


Ok to get correct tension on chain, basically loosen it a little until the chain on the underside of the bar is hanging a little... Now start tightening it up again. Basically you want the chain (the main part of each link) to be just touching the the underside of the bar. This will give correct tension... Note that chain does expand as it heats up so it may loose tension... so this is perhaps best done when the saw and chain has warmed a little. Also, new chain will stretch a little naturally so check tension each tme you use the saw.

If you do not know hoe to sharpen a chain properly, it is best to get someone else to sharpen it, or buy a new chain... Eventually all chains will need to be replaced because they can only be sharpened so many times before the cutting teeth become too small to work effectively or safely.

As for oil, if it is an electric chain saw, you only need chain/bar oil. Any good name branded bar/chain oil designed for chainsaws will work well.

Please rate my solution on FixYa!
Thanks.
