crank play specs are in the manual, available here....

as for that piston "crumblies" in the cases, i'll never chance trying to flush it out again. last time it only lasted a few rides and took out a new top end when it did.
it's full rebuild from now on for me...split the cases and replace at least main bearings and seals, if the crank specs out and doesn't have shrapnel in it.
