I have had a trans leak on my Deere for a few years now. I decided I would try and fix it before this mowing season. It seems to be coming from up high, since the whole thing is covered top to bottom with fluid. Belly pan included. My question, any tips on where to start? Anything common on these for leaks? I took a few pics hoping it may help. Thanks!

CT, Nothing looks apparent to me from pics. Hydro input shaft is rusty, so probably not input seal. Start Tractor and see if you can see leak. Move free wheeling lever off of valves, that's a "typical" leak area...and that would be from the pins sticking up. Other than that, just look around ! Bob

Thanks for the reply. I cleaned everything off good, started it and watched fluid come out of the top off both of the valves. Do you have to replace the whole assembly? Looks like there are o rings on them, but not sure how that would stop fluid from coming out of the "push pin" area.

It may be as simple as lubrication and exercising the valves until they fully free up.

I have heard of people rebuilding their own, but it’s not as simple as pulling and replacing an o-ring. There is someone on eBay that rebuilds them, or new ones from JD, or the pump manufacturer.

If you do have to replace those relief valves, you can get them from this company. LJ Fluid Power Inc. Phone is 269-623-4150.

Valve number is LJ- 3103132. I'm assuming they are still valid. I bought mine for my 316 in 2010. At that time, they were 58.00 apiece.

Thanks for the info. They move freely. No sticking at all. Weird. By the research I've found, it looks like a little o ring on the plunger inside. Guessing the fluid is getting past that? I may just need to break down and get some.
