    I just finished putting an engine back together. But this engine has some end play ? crank is moving in and out ? I tried moving the fly wheel closer to bearing no help. I rechecked bearing to make sure bearing were the correct thickness, okay there ? Any ideas ? I've built many engines over the years, this is something new ?
    Thanks dave B

    If it has a brass collet, sometimes they ware down on the back side.

    All the motors I know of lock up crank position on the front bearing.....
    The crank end play is locked up tight on the front bearing...
    If you are feeling end play after everything is tightened up you are feeling the slop in the front bearing itself...

    Mr. Rod is correct. Nominal end play from my database is between .0025 and .0035 inches, both directions, assuming there is no preload. No motor leaves my shop without end play after assuring the crankshaft is in the correct position.
