Thanks for the replies. With the sump off it was clear that the main
bearing were still tight, it is the flange attached to its drive gear that
has play. The oil was pretty clean with only a small amount of brass flakes
and a little fuzz on the magnet so I think it will run a while yet.
I changed the flange seal on one side, drove it today, and checked to find
that it is leaking about the same on that side. Is it likely that this leak
is from the oring sealing the bearing support? Has anyone succeeded in
sealing this from the outside with some type of sealant instead of taking
it apart to change the oring?
Thanks for any help,
Ray
