    m20 5 speed swap pilot bearing orientation

    When swapping my m20 to 5 speed, I became confused on how the pilot bearing situation should be properly layed out.


    When I bought a new bearing from the dealer, it was now superceded to a sealed bearing. So, I just assumed that the covering plate, the felt ring, and the covering cap are now NO LONGER NEEDED....

    If anyone can shed a little light on this, I would appreciate it. I've had my car running for quite a while, with the bearing only installed in the crank, and boy that shit rattles its ass off, especially when things get up to temp. I'm running all sorts of different parts in my clutch department, an aluminum flywheel, and sourced my box from some clown that thinks its cool to ship 260's UPS with only a couple laps of bubble wrap.

    I really feel that when the crank gets warm enough, the bearing walks forward and backwards on my input shaft, and I should have at least run that covering cap, cause it should be the main thing to keep that bearing stationary.

    I'll let you know later today. I'm finishing my swap today and I did the same thing. I just tapped the sealed bearing into the crank--didn't use the felt or either of the cases. I was told by an old, wise BMW mechanic that the cases and the felt were designed for the old, ball bearing type pilots.

        Okay, just finished the swap and the tranny works fine. I tapped the pilot bearing in about one centimeter in the crank. I have no vibration at all. I'm stoked. No more auto! If you have any other questions just PM me.
