The first question that comes to mind is whether or not the outside seal would have held oil in this loop so it all didn't just run out into the engine? It doesn't look like a setup that would keep all the oil within this assembly forever.

MikenOH,
Yes, that is correct, that is my theory, unless any verifiable info to the contrary can be produced.
Yes, I verified the seal will hold oil in the tank so to speak, even in boiling water for 2hrs. with no oil leaking. I know 2hrs. isn't long enough for a test, but long enough to see if the seal will ripple. I too think the seal will fail but when and why is my questions.
The next test will start today and see if the bearing/seal will do the length of time in mileage. The shaft will be spinning at 3500 rpm which ='s 7000 rpm engine spd. with a final gear ratio of 3.44 = 152 mph approx. top spd. So every 24hrs run will = 3648 mi. a day x 100 days = 364,800 total mi. Granted, no chain pull on the shaft, but I am looking for a used lathe right now to set up a rack to run chains.
