In my current 1983 3.0L engine assembly process, I have concern with the intermediate shaft bearing inserts. Both the end-play and the insert sitting high in the case. The case has been had the line-bore checked. The engine has never been apart since initial Porsche Factory assembly, nor has it had a catastrophic event.
End-Play: With a new shaft assembly, the thrust clearance was undetectable value. I saw a video, from a well know guy, about tapping the shaft to force the bearing into the case to gain clearance. All my manuals don’t touch the subject. The little spec book does give a value, but nothing on how to accomplish the value. The bearings are Glyco brand made in Poland. I had higher confidence on the Polish made pieces. I’ve heard that the ones made in South Africa have had issues.
Bearing Shell Sitting Proud: I installed the shell half in the case and tapped it into the case. Both the bearing shell and the case were clean, free of burrs. The bearing shells sit proud by .015”. I have “Porsche OEM” bearing sets on order and will see how they fit. Any wisdom would be appreciated.
