QMB139 Oil Seal Behind Clutch Size

[twitchytoes]

Would anyone happen to know what size(s) are used behind the clutch/pulley setup for a QMB139?  I'm more or less positive that's where the leaking is coming from in my CVT cover but haven't taken anything apart to really investigate.  Oil is only found on the area below the clutch/pulley, as well as said area around the outside of the cover.  Previously changed my gear oil and put a good bit too much, being the first time I've done gear oil, I wasn't thinking and went by the "fill til it pours out" that you see in a lot of places online, except I had it tilted when I did that, as well.  I've since drained and measured to the amount stated on the cover, off the top of my head I recall 120mL.

Oil can leak from an overflow passage, but that's not under the cover so you are likely on the right path with the seal. You can clean the area and then take a quick ride to see if that's where it comes from to be sure.

Anytime you need info on a seal or bearing, take a look at this :

Thank ya much. I cleaned stuff up the other day and just replaced some cover screws yesterday but haven't checked the leakage yet. Gonna be ordering loctite to get everything done right so figured I'd get this oil seal taken care of then.
