MS440 o ring question

[Ronie]

I put the seals in my 440 this morning and it had a small leak between the sleeve and the crankshaft on the clutch side, I put a little grease in the sleeve and that stopped the leak, is that what you do or do you find an o ring that fits, the only OEM o rings for sale that I can find are over in the UK?.

I had the same issue with my 044. I believe they discontinued the O-ring because it would over time burn up and disintegrate. I packed mine with a bunch of grease and it did the trick.

I was just looking at some 044 and 440 diagrams and there's not an o ring listed.

I guess the way it's made is when the clutch is tight it should seal up, on my other 440 I did't use grease or a seal and it didn't leak.

The O ring is listed on the early 044 parts list, but not on the later 044 parts list.

Plausible

I've just used grease on a bunch of them without issue.

@tree monkey has done a blue million of them with grease. If anybody would have found fault with it, it would've been him.
