I have this engine on my 13 year old Scag Freedom Z 52" ZTR mower that I bought new.
My mower presently shows 484 on the hour meter. I was just wondering what the expected life on this engine is.
I've been having trouble with leaking oil and my Scag dealer couldn't find the exact source. They said it would be $900 to reseal the entire engine but the money may be better spent towards a new engine which he said would be a Kohler. I told them do neither right now and they brought it back to me with no bill.
I wasn't satisfied with that answer and am in the process right now of trying to find the source of the leak myself. I think I found it and it's the upper crank seal. Thanks to info after searching on this site, I found it was easy to remove the flywheel. I had to clean everything well, then reassemble and mow the yard again before tearing it down again to be able to trace the oil leak path. That pretty much led straight to the crank seal. Waiting on a new one to get here so I should know for sure this fix works this week.
Anyway, I would appreciate thoughts how much more life this engine should have lift in it. It does run great right now.
Wet all the way to the top of the seal:

I can't see where why the seal leaks after taking it out. No damage on it. If it's the culprit, it must just be wear I can't detect.

The rest of the mower is in great shape and like I said, other than the oil leak, the engine runs great.
