Title: Buying used saw - checking crank
Post by: MNBobcat on December 23, 2018, 07:11:42 PM
I'm going to buy a used saw and put a big bore kit on it.  I know how to check bearings on each side of the crank for play.  Is there any way to determine if a saw is likely to end up with a spun crank?  Just wondering what I should  check on the crank before buying.

Crank failure is nearly non existent on saws that have a big bore kit available to them.
Crankbearing failure yes, but a spun crank I have never seen in a chainsaw in over 25 years of servicing them.
