Hi, have a few questions about rebuilding an AC model C engine.

The rebuild kit I got Has a cork seal for the main rear oil seal, If i use it how do I install it? it dosent seem to fit tightly "thickness" in the seal plate Do I use RTV or silicone? also is there a Lip seal available to replace the cork one? I cant imagine a cork seal on a crankshaft surface, the one that came out was a strip of rubber.

Im getting ready to reassemble this and I dont want oil everywhere...

Also I have 2 different front seals in the kit one is green one is blue how can I determine which one to use? or is one for something else?

Thanks All.

I think the felt seal is the best but the cork does work and for a long time, I might add.
First make sure it has not dryed out to the point it will break when being placed over the crankshaft hub. If it is soak in warm water over night. Use silicone or something that is about the same like a permatex product in the groove, wipe off all the extra, and bolt on before the sealant sets up.
There is two different outside diameters on the two front seals in the kit. I would guess that you will need the smaller one. I have, where the front plate has been damaged, machined out the plate for the larger seal. When doing thhis I leave a .005 press fit.
