Happy Holidays List!
I'm sending this E-mail on behalf of Cosmo Kramer, being that he is 
still _*not* on line_ at his home & dropped off the list for some time. 
He is able to do some 'back reading' of the TRIUMPH Digest which I send 
to him about every 3 months. So you are still in his heart & mind with 
your E-mailings. THEREFORE: PLEASE send your replies to me - 
wmpless@iprimus.ca.

Cosmo's questions are:
1- What is the best way to set the Rear Engine Seal on his TR4A? When I 
rebuilt the engine, I followed the Factory Manual to the letter. I have 
the Mandrel made to the factory specifications & then proceed to follow 
the operation to setting the REAR MAIN SEAL. After a while, I noticed 
that it was leaking. Then I read on the TRIUMPH Digest List that the 
factory specifications where WRONG!
 
2- What IS the *CORRECT* dimension that the Mandrel should be for the 
_Wet Sleeve Engine_?
 
3- I was planning on leaving the Crankshaft in the engine (engine is out 
of the Garage Queen NOW  - my TR4A), because I really don't want to have 
to remove the Front Engine Plate, then remove the Crankshaft. Loosening 
the outside bolts & moving that (original) seal  in against the 
Crankshaft. Followed by tighten the outside bolts & calling it done.
What is the list's input on this? Please be specific on this reply.
 
4- If I have to remove the crankshaft, is it a good idea to repack the 
felt into the engine DRY, as one of my Healy friend has mentioned?
 
5- Any 'secrets' you may have on how to stop this Rear Main Seal from 
leaking, would be GREATLY APPRECIATED!
 
I really miss not being on the list, but my E-mail box would be packed 
if I was, being that I have to go to the Library to read my mail. TIA,
-Cosmo Kramer
