SHORT VERSION, before I hit the sack:

Endplay is set by moving the flywheel farther onto the crankshaft after loosening the two bolts that clamp the flywheel to the crankshaft. Be SURE you get them TIGHT when you are done.

There is an oil slinger just inboard of the flywheel that is pinned to turn with the crankshaft/flywheel. If the pin wears out, it will slip around and leak. There is a cork or rubber ring inside the slinger to keep oil from sneaking out between the crankshaft and the slinger, as well.

Note the flywheel is timed to the crankshaft for dynamic balance.

When we reinstall a flywheel one dude holds a sledge over on the other side up against the clutch drive disk big center bolt while the flywheel side dude armed with an oak block n hammer drives the flywheel in to her milk tight about as far as she goes, I think the spec is something like only 0.010 i.e. pretty much all the way in which reduces any excess side to side loose end play.

If shes throwing oil behind the flywheel make sure the lil pin on inner flywheel is fitting into the open slot in the oil slinger (located in the D shaped bearing/seal housing)... If the inner cork seal is bad we soak the new one in hot oil prior to installation (its in the D shaped bearing/seal housing also)

If the flywheel isnt re installed on the correct crank spline its VIBRATION CITY as its heavy side must be 180 opposite from heavy side of clutch drive disk. Torque them 2 big flywheel bolts tighter then Dicks hat band.
