Here you can see the rear main bearing half lip seal. This has been a problem because after extensive searching we could not find the right one even in the US. Finally the owner tracked this Chrysler item down and with a little alteration and mandrel tooling we managed to fit this, allow it to progressively settle under a load and trimmed to give an initial large nip as with shell bearings and then after further time under load and with use of a mandrel made to crank journal size, we finally carefully shaved and oilstoned the seal joint face to give a nominal 0.004" nip.
Here we are using feeler gauges and micrometer blue to gauge the contact of thr lip to see its position and the amount it grips the feeler gauge. Access is tricky throughout.
