say what kdeal?....there are at least 6 reasons why a crank could be pinched too tightly, and any tightly-squeezed installation will cause some left-side bulge of the crankplate race -- while it smashes hard-pressed against the rollers and plastic outer bearing cage,...which could hold out the gear by many thousanths.
But OK, he has now stated that the crank sideplay is OK and not pinched, so those causes are now ruled out.
One other thing just to mention...the primary-gear inner O-ring? Did you happen to slip the new one over the crankshaft?...instead of inserting it inside the gear? I have run in to that question before on a phone call, where a guy was looking at the parts catalog and did not yet notice the inner-gear placement for that O-ring.

Boomer,
You cannot squeeze the left side of the crank any further than the bearing and cartridge plate is going to allow you to do so. So, the right side crank bearing is a moot point. If there was a problem it was with the crank having mismachining or the gear not going all the way on.
