Hey, guys. Haven't posted in a while but I've been checking in regularly. My '55 is leaking a lot of oil from the inspection hole after running it hard for a while. I assume this is the rear main seal, right? It's had a slow leak forever but got a lot worse all at once at the end of mowing season last year.
Thanks!
Clint

Re: Oil dumping from inspection hole
Clint,
In order to check another possibility, back your Cub up a slight grade and stop it. Quickly get off and observe the inspection hole. If oil flow increases, you have a transmission front seal leak. The torque tube is shaped such that leaking oil forms a pool and by backing up the grade you’re draining the pool. If no noticeable increase, the rear engine seal is the culprit, either way a split is in your near future to replace one or more seals. The Bash is coming up, if you can wait that long.

Bill, I kinda ruled that out because the oil is black, not milky brown and smelly like transmission oil. And the engine oil level went down after the leak.
