I changed the hydraulic filters on the side of the tranny and ran the machine for about 45 minutes and shut it off. 10 minutes latter I started it and the front filter started leaking badly. I reseated the gasket used it again, shut it off, and the next time I started it, it leaked. Now I can't move it because when it starts it leaks even after seating the gasket several times. I think this problem is beyond just a gasket leaking. It seams to have a lot of pressure in this filter housing.

I have not had this tractor for long and if this is a sign of a major problem I may not have it much longer. I only use it around the property to dig drainage and pull rocks, it is not for comercial use.

Thank-you in advance for any help, Skip in CT

Are you sure you're getting the o-ring installed properly? They are easy to cut when installing, especially if you're not used to doing it. Use some heavy grease to hold the ring in place, and gently rotate the cannister back and forth while tightening it until is is drawn all the way.

I am pretty shure the gasket is seated properly because it ran for a while before it leaked. I will check again. It shoud have a groove to sit in instead of a shoulder to sit on.
Thanks for the reply jdemaris.

Well, as I said, they're easy to screw up. I worked as Deere mechanic for a long tme, and seen a lot of leaks after filter changes. For installing, the way that works best for me - is - put the o-ring in first, on the tractor - not on the canister. Heavy grease will hold it up in place. Then do as aforementioned. If you try installing with the o-ring on the canister, it will be more apt to cut the ring. As far as a groove being better than the shoulder that's used - yes - or better yet, a throw-away cartridge. The way laws are now as they relate to oil spilled on the ground, some of these older tractors are almost impossible to service out in public view. One case in point - I had to go out and service a brand new backhoe and a crawler - first 100 hour service. It was for a town government. I got there, and there was a newspaper reporter, the town mayor, and a few other officials doing a photo-op about the new equipment that had been purchased. I had to make up a story and leave. I didn't dare to the work because it was virtually impossible to do the job without spilling some oil.

I have a very large drip pan collecting any oil when I change these filters, but thanks for the heads up. These were Fram filters from TSC (the only people open on Sunday) do you think bad o-rings?

I doubt it, but anything is possible.
