One of the advantages of the standard seal, is that there is nothing to
fail from sitting around, unless the cap packing dried out. I would advise
double checking where the oil is leaking first.
BTW: I was the one to arrive at 2.818" for the seal ID/ correct size for
the alignment tool.
There was a recent post where a seal was installed with the "factory"
alignment tool and once the rear main cap was tightened with the tool and seal
in place, the seal could not be moved. Stop right there if this ever
happens!
Tighten the rear main cap with the alignment tool in place, and Then slide
the seal halfs in place; if they will not slide in, find out what the
problem is before going further. The alignment tool is a good way to check
the
seal ID before you start the process of installing or reinstalling.

Subject: [TR] TR-3 Rear Crankshaft Seal
List,
After taking TR-3B TS#68368 around the block for it's first movement under
it's own power in 30 years, I discovered that the rear main seal is
leaking.
ISTR that there are a couple of options for replacing this seal with modern
technology. TRF's Viton seal doesn't require machining the crank, while
Moss's
does. Are there any other options? Any experience with either version with
regard to ease of installation and effectiveness once installed?
TIA,
John Walker
