Hi Lawrie and Ed,
Your response begs the question, what are the "tricks"?
I have only installed one rear seal kit, it leaked. Stripped it down again
by removing flywheel and rear main cap, leaving the crank in place, saw
nothing wrong so re-gooped it and but it back in. It worked AOK.
A friend installed one and it leaked after 25 miles. Discussion with
Chicago Rawhide indicated a revised seal, with double lip, CR-37389, the
extra lip is really a dust/dirt excluder but I guess every bit helps. (Moss
supply CR-37388 seal, same dimensions but no secondary dirt seal).
On another friend installation, which leaked, the CR guy suggested
installing the seal backwards to get more positive contact on the crank
flange with the lip seal. He said it might leak a drop or two being
installed in reverse but would work. This was done and the seal is working
well.
So what else can we do to improve the seal performance?
Thanks for any info.
Regards, Bob Grunau;
