when installing new pilot bearing from napa, into tilton flywheel, the bearing will spin in the flywheel, not easily but it will turn by hand. Not the inner race but the whole bearing will spin in the flywheel.

I had another non-oem pilot bearing installed in another flywheel(which would not turn by hand in that flywheel), took it out of that flywheel, and installed it into the tilton flywheel, same problem.

Anybody have any simlar issues, and/or input?

 

no thoughts?
