Title: 3 piece crank.Dust caps do u need em ?
Post by: sam hudson on January 22, 2006, 01:27 PM

Ok,my crank arm keeps working its way off the crank shaft.I havent put the dust caps on the ends of the shaft because i havent got a big enough allen key.Is this why the arm is working its way off?? (havent had much experience with 3 pieces...as you can tell).
I thought that they were just there to keep cack out of the shaft end.(this sounds disgusting).
I keep tightening the arm bolts up,but off it wobbles after a while on the track.

??? you should have bolts holding your crank arms on. dust caps cover the bolt ends. This will be why they fall of.
