John I looked through all my purchases last 5 years (I know I replaced mine). I can't find the individual seal purchase but I've bought several seal kits that have the clutch oil seal in it. Now I know the differences, my early nylon was cracked and I found a bearing one but had no reason to open the casing at the time - so I made a spacer.
When I did open it a few years ago I replaced it with the 92050-070 that I'm pretty sure was in the seal kit. In fact I just checked Larry's site at mid-atlantic and repo and they both have the newer -070 seal in it. Finding a individual one - seems difficult.
I don't now about finding the older -025 ??
Info from the old site that I don't think made it over - furture thread searches. Plus MRAXL has some good info too.
If you are using a Ball Bearing Actuator the correct seal is 92050-070.
Currently all of the aftermarket engine seal kits come with the 92050-025 seal.
All clutch releases are interchangeable. However, the ball bearing release must be used
with a 92050-070 seal or spaced out to prevent seal destruction in the H series.
