Title: pressing a crank
Post by: Dutch-K5 Fan on May 29, 2012, 06:03:47 AM

How wide do you press a crank? Measured between the crankbearings
Mine is now 55.65mm, think it must be 55.75 - 55.85mm.

I know that the connecting rod side clearance is 0.40-0.50mm.

Thanks Sandblaster, only I ment the witdh of the crank halves.
And is there a size for crankshaft end play??
I have 1.25mm play, my raceshop says 0.1-0.15 play is good. Else it will vibrate much.
Should I shim it out?
