I have a 1956 TO-36 serial 170185. I was having issues with the lift not working once the tractor warmed up. After taking it apart, we found a small scratch in the piston -- possibly from what was also found, water that had leaked into the case and turned the hydraulic/trans fluid milky and a bunch of gunk was in the bottom. It was drained, flushed and the piston replaced as well as a new seal for the PTO installed. When everything was put back together, the hydraulic arms no longer raise when the lever is moved. I have a feeling when we reinstalled it, we missed something with the lever mechanism, but I am unable to find anything that would help me online to resolve this issue. Can anyone on here help?

Did you replace o-ring on stand pipe and get it in correct place?
I did ensure that the stand pipe is in the correct place. I didn t Roland the irony as it appeared to be in good shape and sealed well on both ends. Do you think that could be the problem? I just thought I didn t get end linkage back in correctly for the lever as there seemed to be no response at all when you work the lever. Is this an incorrect assumption?

In the picture John sent, the levers that are shown, the roller on the pump pivot lever goes behind the levers.
The levers don't move very far, it's a tricky adjustment. You can move the roller lever and make the arms go up and down, get an idea if it's working. Pushing the roller back raises the arms, letting it spring forward lowers them. Be careful not to allow it to raise all the way up, can break the top plate or cylinder! When properly adjusted, the arms will stop just before reaching the end of their travel.
Get an idea where the roller needs to be positioned in relation to the arms, stop the engine and adjust the nut where the roller lever pivots (down below the oil level). Best I remember it's a small nylock nut that stays where it's stopped. Hopefully nothing was damaged during the removal and assembly, the lever mechanism is complex and fragile.
But above all, NEVER reach in there with it running!!!

It's my understanding the owner of this TO-35 did not and or read a Service Manual:
