I'm having a hard time seeing it in my service manual. Which way does the nut go on the shaft? I'm talking about the nut that holds the clutch basket on. Does the hex surface press against the clutch basket or does the round surface? I have it apart and can't remember which way it was originally. Thanks for any help!!

 

If it's what I'm think your talking about, the round surface goes against it. Round surface to the inside.

 

hmm. ok. the reason I ask is I took my primary cover off again today and noticed scratches on the inner primary where the clutch basket must have wobbled and touched the case. I know I torqued it right. I'm just trying to figure out why the basket has so much play in it.

 

2nd that the round portion goes in board, if you have some play it is possible you have cross threaded the nu, remember that is a left threaded nut, to the left is tight & right is loose, it may also be possible that the bearing is bad

 

I know it's left threaded, and the threads are fine. I'll take a look at the bearing in a little bit. It would be nice to have finally chased down the vibration my bike has had for a while now!

 

If you have digital camera I highly recommend taking some pics before and during the disassembly process...... those pics saved my a$$ a few times.

 

I usually do that. I had it back together right. It just wobbles. I suppose it could be the bearing.

 

Clutch hub nut screws on CCW. Torque to 70-80 ft-lbs with Locktite 262 (red). Check primary chain alignment of sprockets by laying a flat edge across the tensioner plate and reading both the clutch and compensating sprocket chain sides: difference should be within .030". If not, you need to increase or reduce shim thickness on the compensator side. The clutch is on the shaft and it is virtually impossible to "wobble" unless it comes off the splines or had no splines: if it did the noise would immediately get your attention! The scratches in your primary are most probably from the primary chain; the chain alignment may be the vibration cause. If you don't have an automatic tensioner (auto tensioner is just that), adjust chain tension after finding the tightest part of the chain. To find this, lift bike rear wheel, put in fourth gear, divide the rear tire into 90 degree quadrants with masking tape, and spin tire while feeling chain where most tension is located. Chain tension should be set 5/8-7/8" on the tightest part of the chain. If vibration is still present, look in "troubleshooting" in Section 1 of service manual under "excessive vibration".
