My 2HP Regal leaks oil from the front of the crankshaft. Upon disassembly this was the sealing arrangement. It has a rope packing between the main bearing and a coned spacer held in by a large washer that just snaps in place. Before I adapt to a modern seal, does this look correct for this engine? I also would like a couple pics of the filler cap/breather for this standpipe if available. Any help or suggestions would be appreciated.

Also need to look at condition of crankshaft stub - Suspect will be corroded/worn, so lip seal will have short life. I usually fit Speedi sleeve stainless shaft sleeve so lip seal has better surface. Have also hard chromed similar problem shafts and this is another option. Expect will need to machine out front cover to take seal, which is a non-reversible action.

Andrew,

My shaft is in good shape, and if I put a seal, it will be in an adaptor bushing so I don't have to machine the front cover. Hoping to verify if this method of sealing the crankshaft is original, and if so would like to make it work.

I think a check valve breather cap will help, and maybe turn down the oil pump flow a little.
I saw another Regal Y with a check breather cap, but it had a different filler pipe.

Thanks for your input.

Jim

I found a picture of the cap and it should be easy enough to duplicate.

That does not look like proper graphite packing, which is still available from some marine suppliers.

Robert,

It looks like the packing will also seal the drain passage at the 5 o clock position with this stack up. Is the drain just for the oil wicked from the packing? I may try a new packing, along with a breather cap and see what happens.

Thanks,
Jim
