Massey Ferguson TO-35 3pt problem

Hello all,
I have a 1955 TO-35 with a front end loader and my 3pt arms fall whenever I switch from the 3pt to the FEL. I was wondering if maybe I had a bad seal somewhere inside. Its not a fast leak like they drop all of a sudden but more of a gradual fall over a couple minutes. Any help in this area would be greatly appreciated!

Good chance the lift cylinder rings or o-ring which ever is has is going bad. Not sure if it has the inspection covers like the Ford have or not but if it does you can pull one and have a look see

Cool thanks! Ill check that and see if I can tell whats going on.

If it has the inspection covers you can pull one off then look inside for oil dripping down from the cylinder which if like the Ford is in the top part of the lift cover.

They don't have perfect seals, but should take more than a couple minutes to drop.

Chances are the seal rings and cylinder are galled and leaking. You can look in through the
inspection covers for fluid leaking down from the cylinder. It can also be blown orings on the
standpipe.

Changing the piston and cylinder requires lifting the top cover. Best have a shop manual before
attempting this. The cover is heavy, the control linkage extends all the way down to the pump
controls and is delicate, easily damaged. You will need some means to do a controlled lift and know
which bolts to remove.

Chances are the draft link boot will need replacing, be a good time to do that if you go in.

Unless you need the lift, be easier to just chain it up when not in use.

They are made to drop once engine is shut off, but not sure how fast on that model.

Which to my way of thinking would be the the same as shutting the engine off. Meaning there would be no hydraulic pressure going to the 3 point lift cylinder.
