Hi David

Thanks for the response, my picture choice was poor resulting in a difference in part terminology, I was referring to the Pilot Bearing 4.352 the picture I posted is unclear it is of the Main Shaft 4.403 and not the Main Drive Gear 4.351. (see exploded view picture) Good point though the I did replace the pilot bearing in the flywheel of the new engine so that it would mate correctly with the original transmission.

The pilot bearing on the main shaft is turning in all gears accept 4th, which adds to the confusion because I only have noticed the "catch" or single chatter in 3rd gear when going down fairly steep grades 6-8% (steep for on road).
