[QUOTE="thetool, post: 20516, member: 1534"] Woops------=) All what I said before---------”never mind”......... This is a common leak, and you do have to pull the shafts, or rather sleeves and shafts. The sleeves have an o-ring and a back-up ring. Dirt gets in and wears the seals and bores, then you have a leak. Ask your local Bobcat service guys for a Service Bulletin dealing with “pump servo sleeve replacement” or something like that. They can search it with those words and print it off for you, and you'll see what parts you MAY need to fix this, since it's older. Yeah-it spews oil when you pull the shafts and sleeves, so I'd drain it. This is a tricky repair for the guy who's never done it. I've done it a lot. If you're going to do it, I'll be happy to talk you through it. [/QUOTE]
