Oil leak

[mark777]

HGM,

I want to think there is a seal in there as well as the "O" ring...just not certain. On many of the smaller models you have to pull the top of the case to remove snap rings before the drum will slide out. Not sure about the YM2000.

I only mention this because I had to replace the whole hydraulic case as someone tried to remove the drum without removing the snap rings...$700 (used). Also, if the shoes are oil soaked then they never seem to work correctly again.

Good luck,

Mark

Good tip Mark, I appreciate it.... Looks like I should tear it down before ordering parts..... /forums/images/graemlins/crazy.gif

Well guys, got an update for you on my leak.. Hope these pictures can help someone else too..(give you an idea whats in there)


I finally had a free day to tinker with my leaking "brake" /forums/images/graemlins/smirk.gif.. It wasnt the brake..

The leak actually does come from the o-ring I was thinking it was.... The problem is that it is on the differential carrier /forums/images/graemlins/blush.gif..

Another veiw...

In this one you can see, in the top left, the differential bearing(next to the ring gear).. The cast iron part to the left of the bearing, is the peice that needs to come out.. /forums/images/graemlins/crazy.gif The whole chunk..... Unfortunatly, what cant be seen in the picture, is that the differential drives an axle on each side through gear reduction.. The problem is that in order for the gears to mesh, this bearing housing (that I must remove) is notched out to allow the gears to mesh.. For me to get the housing out to replace the o-ring, I must remove the rear cover(where the PTO comes out) allong with the PTO shift linkage.. Then the axle gear must be removed, just so I can get this housing out and replace this $2(?) o-ring..... /forums/images/graemlins/crazy.gif

Needless to say, I'm a bit frustrated.... Doesnt appear to be all that difficlut, just time consuming.. Unfortunatly, due to my schedule I needed to cut a corner... So a little silicone later, I think thats ok... Now I need to het the gaskets and seals to put the rest of it back together so I can use it when I get back in town.... /forums/images/graemlins/crazy.gif

Oh, well... Just thought I'd post the pics so the guys that didnt know what was in there could see, and maybe the guys that know something about it can correct me and give me an easy fix /forums/images/graemlins/grin.gif..

Are you sure the O-ring is leaking? I have replaced the seal & collar on a lot of YM2000' S, but never had to change the O-ring.

Danny,
Are you talking about the axle(stub shaft) seal in the brake drum area? If so, it was dry.. Mine is definitly leaking from the o-ring... I think the silicone is my ticket here /forums/images/graemlins/grin.gif.. Its a bigger job than I care to do with spring here, so it will have to..

Have you seen the o-ring leak before?
Thanks for the input..
