bearing problems

[pektrt]

I keep goin trough bearings on the clutch bell on my rc. They fall apart and all the little ballls inside go everywhere. Any ideas on what could be destroying these bearings so fast?

out of round clutch bell or the fly wheel is out of balence. or both.will cause the bearings to fail.

 

[flash]

gear mesh too tight or loose? heat is a common cause of these bearings going bad too. check your clutch to make sure the springs are good and pull the shoes back in. if a shoe is hangin up up not retracting it will build up a lot of heat fast.
another thing you can do is make sure the clutch bell is spinning freely when its mounted. it should spin and should not have too much play. make sure it is shimmed correctly!
