1981 Yamaha xj550 maxim.anyone have a diagram of the correct order of the metal and fiber clutch plates so I can put back together correctly?

Hi Kevin:

If it's anything like the clutches I've messed with, there will only be 2 kinds of plates, metal, and fiber.
If you stack them up, alternating fiber/metal/fiber/metal until you run out, you'll probably end up with a fiber on top.
It will be like a "Dagwood Sandwich" with fiber on both outsides.
This will be the "clutch pack" that you install in the bike.

Hope this helps. It's great weather so you should be out riding.

1998 dodge ram 1500 clutch replaced mounth ago now has shutter in it when pulling out could i have gotten a bad clutch or could there be another problem

Its not the clutch that is the problem its the flywheel.Whenever you replace a clutch you have to get the flywheel refaced because it will have hot spots on it and is not true or perfectly flat unless its machined just like what you would do with a brake rotor that is warped.So get it machined and your problem should be fixed.Also make sure you have'nt damaged the new clutch plate or play it safe and put a new clutch disc in it..

Need to know how to install clutches.

I assume you mean clutch plates. Mount the outer clutch basket and the inner clutch hub then install a fiber plate, then a metal pressure plate, fiber, metal, fiber and so on. You should end up with a fiber plate. Some clutch sets have two fiber plates that are .005 thicker than the others. The thicker plate goes in as the first plate and the last plate.

2005 Heritage parked up for 12 months all fine. brought it out and now the clutch not working?

It sounds like the clutch is "stuck". This is when the fiber plates stick to the metal plates and will not disengage the clutch. You can try putting the transmission on high gear, pulling the clutch lever in, and rocking the bike back and forth a bit. If it's going to come loose, it'll do it in the first one or two bumps. If it takes more than that, you may damage the fiber discs.

To fix the problem, you must disconnect the battery, drain the primary, and remove the outer primary cover. Remove the six hex head bolts from the clutch spring holder and remove it and the spring. Then remove the fiber and steel plates one at a time. If you find any of them stuck together, pry them apart or soak them in gasoline until they come apart. Be careful in your use of gasoline as a cleaning agent. But, a varnish forms on the plates that mineral spirits or other solvents will not cut. Gasoline works but is very hazardous to use. Once you get the plates apart and cleaned, lightly sand the fiber discs using a figure "8" motion on a sheet of medium grit emery cloth. Reassemble the clutch and adjust.

To adjust the clutch, find the cable adjuster in the middle of the cable. Break the locknut loose and turn the adjuster inwards until you get a lot of slack in the cable. Then, go to the clutch and break the locknut in the middle of the clutch assembly loose. Turn the center bolt inwards until you feel a resistance. Do NOT force the screw, turn it inwards until you feel resistance. Then back the screw out about 1/2 turn and lock the locknut. Go back to the cable and adjust the adjuster outward until you get 1/8" of freeplay in the cable. Squeeze the lever a few times and recheck the freeplay. If correct, lock the locknut on the cable adjuster.

Good Luck

I have a 2004 yz250f. I bought it used after not riding for many years. I had to adjust the clutch so tight because the bike would jump or stall when I put it in gear. The clutch is obviously worn, whats...

First of all if the bike sat for years the plates may just be stuck together. Disassemble and inspect the clutch. For racing some clutches are all aluminum plates. To last longer two or three plates may be metal. Some people put in all metal because they do not race and that set up will last longer. Aluminum plates are soft for better clutch grab. Aluminum plates tend to wear out faster than the the friction plates. So when you inspect the plates figure on replacing all the aluminum's , your friction's and metal's are probably fine.

How to put a clutch together on a 1999 yz125? how do you put a clutch together?

Go to there you can see an exploded diagram of your clutch. Note that you start with a fiber friction plate, then a metal clutch plate, then a friction plate etc... ending up with a fiber friction plate. Be sure to unbend the locking tab on the hub nut before trying to remove the nut.

I have a 05 Yamaha yz85 and I would like to know how to put in new clutch plates in

Just remove the right engine case cover and the clutch is accessible.
Remove the five spring retainer bolts and springs then remove the pressure plate. Remove the fiber friction plates and the metal pressure plates then reassemble with new fiber friction plates. The metal pressure plates will not need replacing unless they are warped. Warped plates are extremely rare.

Reassemble per the diagram below. Note that the first plate and the last plate are fiber plates and are just a bit thicker than the rest of the friction plates. Please rate my answer. Thanks.

Chatter noise from primary drive case when starting to releasing the clutch in first gear as you let it out further under more load it will stop. 2008 Road King

Sounds like you need to clean the clutch plates. This is rather unusual on the newer bikes but quite common on the older Shovelhead bikes. Make sure you're using the correct lubricant at the right level in your primary.

The clutch disc can get a glaze on them. We disassemble the clutch and wash the fiber plates with gasoline. Yes, I know gasoline is dangerous to use as a cleaning solvent due to it's flammability. Just be careful as it is the cheapest solvent that will cut the glaze. Mineral Spirits or diesel fuel won't work. Make sure you notice how the clutch plates are postitioned in the clutch basket. The middle plate is usually a spring plate. Once cleaned, lay a piece of fine emory cloth on a flat surface and sand both sides of the fiber disc using a figure 8 motion. Not much, just enough to knock the remaining glaze off the disc.

Now, put the clutch back together and adjust it properly as improper adjustment is probably what caused this to begin with. Back off on the adjustment on the clutch cable. Make it as short as possible. Now, in the center of the clutch pack there is a screw with a locknut on it. Break the locknut loose. Adjust the screw inwards until you feel a resistance. Then, back the screw back out 1/2 to 1 full turn. Lock the lock nut back down. Now, adjust your clutch cable so that you've got about 1/8 inch freeplay at the clutch lever. While you're in the primary, check the adjustment of the primary chain if your bike is equipped with the manual adjuster. Good Luck.

How do i aline the cluch plates on a dt125r

Hi Ma_beveridge,

I guess ,since its 10splines you ought to fit in 5 steel plates ,just make sure that no steel plates come into contact with each other except with the clutch plate in between them.

Hope this will help .
