[TR] TR-3 Rear Crankshaft Seal

[Catpusher at aol.com]

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
