I've got my 036 back together.I've been told that the reason the crankshaft broke to start with was because the clutch drum was worn out and vibrated the shaft to failure. So,I'll replace it. I was thinking that these normally used 3/8 chain, but some stores show .325 hub/sprocket package for the 036. I've got a 1/2 dozen 3/8 bars laying around, but if a .325 will work better on this saw I can go that way also. Thanks for any advice.
