End Play

[Brad Christy]

^^^ Listen to this guy.... he gets it !! ^^^

With both oiled bearings in the housing, the crank should just slip into the inner races of both bearings...by hand. Should drop right in with little effort.
The "step" on the crank should butt up against one side of the front inner race of the bearing and the flywheel cone up against the other side. Install the flywheel, torque it down and the crank should spin freely with very little end play.

Sometimes the cone will have a ridge where it butts up against the inner race of the bearing..
caused by slippage or spinning on the crank.
If it is not to bad it can be dressed with a file or trimmed up in a mill or lathe. It's kind of a one time thing though,, cut too much off and bad things will start to happen.

Frank,

Yup. I've been known to make spacers to go between the flywheel cone and the bearing inner race to put some distance between the back wall of the flywheel and the front bearing face. I also flat sand the bearing mating face of the flywheel cone to remove the "wear groove" that always seems to find its way there.

Thanks. Brad.
