I noticed a fairly bad leak on the hydro on my 129, and quickly narrowed down the problem to the relief valve pictured below. This relief valve came with the ported pump that I used to install the hydraulic lift conversion.
I still have the old pump, which has the push buttons on the relief valves. I'm wondering if I can swap out the defective valves for the ones in the old pump, I am using the original tunnel cover for the 129, so I can operate them manually if necessary to move the tractor. The other option is to try to repair the one pictured, I believe there is a faq somewhere. but it seemed like a tricky and difficult job.
