Pilot Bearing for an '87 3.2l w/ 3.3 turbo Crank

[tgarnoldo]

I am in process of rebuilding my 3.2 l and because of the spun bearing I had to replace the crank. The only crank I could find was from a 3.3 Turbo. I went to install the Pilot bearing today and realized I had the wrong part and also found that the correct parts bolts on to the end of the crank (per Bentley) w/ 3 bolts. My crank only has one taped hole. The question is, how much trouble am I in? Can this be repaired short of finding a new crank and tearing down the entire engine? Help....


Thanks,

Can you post a pic?

Wanye,

Sorry, I don't have a digital camera. From the Bentley manual (in the clutch section) there is a photo of the Crank/flywheel mounting flange. This shows the 9 holes for the flywheel and a set of three holes on a smaller bolt circle for mounting the pilot bearing. My new crank has only only one hole in this general location.

I don't remember taking this bearing off when I disassembled the engine and it went to Comp Engineering with the flywheel for balancing. I was wondering if you had any pictures of the 87-89 pilot bearing. I looked at your website, but no picture existed.

Thanks,

Arnie

Your 1987 has the G50 transmission, which doesn't use the same pilot bearing as the earlier cars which used the 915 transmission. Your pilot bearing is pressed into the flywheel - not bolted to the crank. So the pilot bearing for your car (931.102.111.00) should work with this crank.

The Bentley book is probably incorrect in this area...

Wanye,

Thanks for the research. I had other similar inputs.

Thanks,
