Friends,

The arms on my 1950 TO-20 are intermittently stuck in the up position. My understanding is that there is a pressure relief valve approachable through the right side of the transmission that usually needs to be removed and cleaned.

I have no idea what to look for when I open her up. My manual is just for engine and clutch. Could someone give me a better description or email a photo from a manual.

If I drain the fluid, I think I am supposed to replace only with straight mineral oil???

Thanks

Frank

Sorry you have totally the wrong info here, the relief valve or safety valve cannot be cleaned as it is sealed and if you take it all you can do is replace it. If the linkage is stuck at the top this means the oil is not being released from the lift cylinder so more than likely it is the Control Valve that is stuck. To free this, place the PTO lever in drive and then remove the round plate it is mounted on. You will see a long pair of "flat" rods hanging down from the top, if you start the engine and put the hydraulic lever to the bottom (if it is stuck up) and move the rods with a long screwdriver (or similar)so your hands don't get inside, don't put ANYTHING into the oil hands included. try to move the rods gently back-wards first, they should move about an inch, then move them forwards. This should free them off. If you still have trouble after that email me and tell me what is happening...John

For the oil you can use GL1 90W or if you are in a cold winter climate use Multi-grade 15W/30 or 15W/40 whichever they supply in your area. The oil should only be drained when as hot as possible so everything will run out , no use doing it if it is only warm or cold as all the crud is still inside, leave draining overnight.

Frank, NO! that ain't the right manual, unless you want to service a Sherman add-on tranny for your TO. You want the manual right above that, the service manual for the TE20,TO20,& TO-30 for $36.95 from the "manuals" tab above. There's other places to get manuals, and maybe save a few bucks, besides this fine site. If you have the time, shop around.

Frank, on your stuck lift arms, no, probably NOT the relief valve. The typical relief valve problem is lift arms won't raise because the relief is stuck open. Lift arms not going down is usually clogged/siezed control valve. An intermittent problem suggests gunky tranny oil that needs cleaned out & changed. On the oil, YES, you are looking for straight GL-1 mineral oil, NAPA & TSC both carry it. You are NOT looking for 80/90W EP grade tranny oil, or GL-3 or GL-5 oil, not the same thing. Some guys have switched their tranny oil over to 15W40 motor oil. That seems fine also, especially if you live up North where cold weather slows down your hydro's. Next time I replace my tranny oil, that's what I'm switching over to also.

George,

Thanks again. I have ordered the manual and am looking for GL-1. I think I will take open the acess door, drain the fluid and spray things down with diesel and drain everything out.

Thanks
