Any sign of any burrs or scratches on the inner race sealing surface?
 
A 1 1/2" dia. pvc piece from a sink drain repair kit is good for tapping the new seal in. Note -- it will go in way too far if you keep tapping until it feels seated. There should be a ridge on the seal and a trough in the case you can use to estimate depth. You can also flip the spacer around to let the seal ride in a new place.
 
Waiting for seal to be delivered. I might as well get the case ready by removing the old one.

With the seal removed, it’s easier to see the relationship between the spacer and the inner race.

As always, Bob, I am impressed with your determination, your tenacity on this persistent, frustrating leak.

Like the USA Women's Soccer Team, you will prevail.

No, here’s a better photo with nothing in the way. It’s pretty representative of what it looks like all the way around.

What does anyone think of trying this product for sealing this leak?
https://www.henkel-adhesives.com/us/en/product/gasketing-sealants--flange-sealants/loctite_510.html

One advantage is it "cures when confined in the absence of air between close-fitting metal surfaces".

Or this one:

You could also try contacting them directly for their opinion, I did that once about another application and was somewhat surprised that I got a fast answer!

Just went out to the garage and checked. The 510 is what I used on the case seams of three different motors, a Sportster, an XS650 and a Homelite chain saw.

One thing I like about the way it cures in the absence of air it that means it doesn't cure outside the joint and is easy to clean off any that squeezes out! Also any that squeezes out to a place you can't reach it does not harden and cause any problem.

Thanks Ken, that’s worth considering, I had never heard of that product.

You've got nothing to lose so maybe try that new sleeve you got? Being a hair shorter shouldn't hurt anything.

I have considered this, and I haven’t ruled it out. I might polish it up and see what it looks like.

Thanks! That’s a good tip!

Thanks Jeff, I’m feeling lucky!

Waiting to see the final solution to this leak. Not sure but my 1982 has a leak under that cover too and so far the couple times I looked at it I've not been sure where the oil was coming from.

Also need to give another try on the horseshoe spring for the starter. Installed a new one when I assembled engine but never knew about the fish scale test so might just need a slight adjustment.
 
Bob, you continue to amaze me with all your threads, how to's, and fantastic pics. Now an index for us that can't find info we want.:)
:bow: Thank you for your attention to detail and your sharing info for the last, oh it seems like 100 years. I'm glad you have found the time
for us.:bow2:

I thought “ Oh what fresh hell is this?”

I landed at DTW @ 3:00 pm and did some chores at home and just drove up to TO for mtgs tomorrow & Tuesday so I’m just catching up. This leak is both interesting and, obviously bloody annoying. Your crack about a “fresh hell” really made me laugh though Bob.

You’ll get it.
