I didn't get these most recent emails until after I put it back together.
I didn't sand down the mating surfaces but I did clean it very carefully
with brake cleaner. I think I did a reasonable job applying the sealant as
I had a very thin and consistent bead squeezed out all around when I
tightened the parts together.
With the oil slinger my housing was widened out enough that I had trouble
getting a good press fit even peening like that guy in thesamba thread
does, *and* using a brand new oil slinger (courtesy of Ken at Vanagain).
This trick to expand out the disc part sounds like it might have helped
though.
What I did was sand the mating surfaces of the slinger and the housing with
coarse sand paper and used a considerable amount of JB Weld, and then
hammered it in and sat it on a hot radiator for a few hours to harden it
enough to feel comfortable reassembling. I'm not filling the transmission
until tomorrow morning so it will have fully hardened by then.
I also rounded out the fork arms carefully (erring on the side of
under-doing it, since I don't currently have any clutch chatter.)
Thanks so much for the help guys! Engine goes back up tomorrow.
