The clutch bell on my R50 V2 has some play in it. I haven't noticed it before and it dose make some bad sounds when the head spools down. Once up to head spead it sounds OK. Anyone have any suggestions on the problem or a fix. I have not tore into it yet...wanted to get some input first.

Hi Larry,

It sounds to me very much like the pinion bearing is knackard, the problems you describe are the typical tale tale signs of bearing problems.

The only way to tell for sure is to take the frames apart and inspect the bearing closely.

Cheers,

Pete.

I had same thing happen. as Raptorite surmised it was the pinion bearing-ish i.e. the bearing was good but its fit on the pinion was very loose ( it had worn away a trough which gave 2mm playin the shaft).
I read somewhere that one shoud CA the pinion to the bearing, thats what i've done now.

Normally what happens is that the bearing goes bad and the resultant wobble eats away at the plastic bearing seats. A good fix for this is to use a piece of plastic electrical tape. Trim the tape to the width of the bearing and wrap a single layer of the tape around the circumference of the bearing. This will secure the bearing without the mess and nuisance of CA and will make it a lot easier to split the frames and remove the bearing the next time that becomes necessary. To prevent premature failure of the pinion bearing get your hands on a greaser and pack the bearing with grease. Do this every time your split your frames and you probably won't have to change the bearing again.

I agree with Capebob on the Greaser issue. Maintaining the bearings is THE path to the promised land! I have three seasons on original Rap30V1 bearings. The frames have been split or replaced many times, and each time the bearings get a pump of fresh grease. I also run the third bearing upgrade, for added support in this area.

Third bearing upgrade, available at Ricks is your secret to success, regarding clutch bell wobble!! They also carry the "Greaser" tool.

That is it, thanks Bob. Here is a link to the third bearing from Rick's. http://www.ronlund.com/Merchant2/me...uct_Code=JCRCSS

Al,

I believe that the 3rd bearing mod only fits the V1

Looking for a problem on a R30, I found the clutch bell had quite a wobble and thought it was my problem. Turned out my problem was I left out the 4 bolts to hold the main gear in place

This wobble was pretty rude (like 1/16" at the top surface), and I determined it was that the threaded hole in the top of the bell was not perpendicular, by chucking it up in a drill and spinning it. I don't think it would cause a real problem, but it wasnt pretty. Nothing you can do can straighten out this problem, if it is indeed a problem. If this is your case and it is a problem, return it for exchange. The Raptor can handle some pretty sloppy parts with no problem., that's a good thing.

Problem Solved...but still need advice!

The problem was the pinion bearing had locked up and had worn away the pinion to the point that the clutch was wobbleing. I have ordered the replacement parts.

My questions are:

Is the Greaser from Rick's the only way to get grease into the bearings? What grease do I use? Will the Third bearing upgrade work on a V2 and is it necessary?

Thanks
