Yes, we were so happy that it didn't fail while out on one of our adventures. From the look of the lips on the seal in the picture above, it was very close to becoming a major issue! Would I have torn it down before it leaked without the diff failure.....probably not because Viton is great! Other folks just installed it wrong! LOL You know, the old adage, if it isn't broke, don't fix it but it made me take a serious look while I had it a part after seeing some of the pictures others posted.

Other's experience saved our butt. Gotta love the Corvair Community smiling smiley

Unfortunately the color doesn't mean anything but since you found a listing that is a pretty good indication.

I'll be polishing the surface the seal contacts plus I'll probably add the spacer available from Clarks and non-hardening sealer of the crank bolts. That should work but if anyone has a part # and where I can purchase a repair sleeve please let me know.

Thanks everyone.

I don't like the sleeves since they really stretch the seal. I think the sleeve kits should come with a special seal designed for the increased diameter.

Last choice for me as well, but, I have used a couple over the years and they both sealed well.


As far as where to find a sleeve, it has been a long time but I looked at Speedy-sleeves and found one with the correct diameter and width to work on the crank and ordered through a local parts house.

Thanks. I installed a new seal after using Emery Cloth on the surface area to get the smoothest surface possible.

I'm now waiting on new transmission mounts from Clarks and soon I'll be back on the road.

PS, As soon as this car is back on the road I have a 1961 Rampside I need to complete.

Could you tell if it was the seal or the bolts or something else?

I have no way of knowing. I installed a new seal, new bellhousing gasket and applied non-hardening sealer to the flywheel bolts. I'm waiting on new transmission mounts from Clark's which will allow me to reinstall the driveline again and be "LEAK" free.

Ray, Like terrible Ted said, the sleeve that goes on the crankshaft seal surface is a great idea. Jeff at California Corvairs sells them & in fact he will not do an engine overhaul without installing one. He can install one for pou but it doesn't sound like that would be very convenient for you. You can put one on yourself. If you are leery about it, give him a call & he will talk you right through the job.
