045 rattle

[cbfarmall]

My 045 rattles quite loudly at idle with the clutch installed, quiet as a mouse without the clutch. When I transferred this clutch to my 056 for a while, that saw rattled similarly. What could cause this? Out of balance, worn shoes/hub? Originally, I though i was chasing a bad rod bearing or loose piston, but the crank is tight and I tried 10 different combos of piston/jug and the rattle was constant.

Thanks, Chris B.

Worn clutch springs, or the backing plate is missing. Your clutch drum bearing may also be worn out.

The backing plate is there. I'll stop by my dealer and get a bearing and a set of springs. Are worn springs common? None of my other 045/056s have this problem.

Thanks, Chris B.

Are the clutch shoes faced or solid metal? The metal shoes may rattle. I have also found that the shoe wears at the point where it sits on the spider. The only cure is a new clutch. Check the spring eyes for wear also.
