Massey Ferguson 35 Replacing PTO Seal
I have a 1957 MF35 which has developed an oil leak on the pto shaft. Is it a difficult job to replace what I assume is an oil seal?
Your advice would be much appreciated.
Regards.

It is easy to replace the oil seal on the pto. To save removing the transmission oil I would suggest backing the tractor up some ramps or a slope so the oil runs to the front. There is a plate with bolts in it to remove from the back of the pto. If you then screw on the pto cap (if you have one) and pull it, it should pull out the boss in which the seal sits in, whilst leaving the actual pto shaft in place. Lever out the seal and carefully replace with a new one. Always change the outer o’ring and clean and lubricate all surfaces before carefully refitting, turning the pto shaft whilst refitting.
If you haven’t got a pto cap to use then you can pull the whole pto shaft out sufficiently to then be able to recover the boss.

I have a T0-35 with the same issue, the Pto seal is leaking steadily. I am assuming the removal process and reinstallation process is the same but i have a dumb question. HJow do you refill it with fluid and what kind of fluid is proper? I noticed a dipstick on the side but i am assuming there is a faster way to refill it. any help would be appreciated!
Hi Kurtis,
There is a cap next to the gear levers. Pour the transmission oil through there.
Oil grade should be SAE-50 for temperate climates.

Hi,
I’m struggling to pull out the PTO boss on my MF65 by tugging on the cap. Having undone the 4 bolts in the picture above i’ve revealed 2 hex sockets – do i need to undo these too? Should the PTO be in neutral or engaged? any suggestions as to what to try next?
cheers
