Massey Ferguson 35 Hydraulics Won’t Lift
Sir,
I have an mf 35 and just recently the lift will pick up and work for about 45 mi’s then it goes down and won’t work again until it cools off.
Any ideas on what the problem might be? Your help would be greatly appreciated.

Hi,
Obviosusly it is some kind of leak or inefficiency in the system that is becoming apparent when the oil is warm and has become non-viscous and thin enough to pass through/by the worn part.
It could be one of several things – worn pistons/cylinders, worn valves, worn control valve, worn rings on the hydraulic ram, wear in the lift cylinder or a leak somewhere in the system.
So where to start looking?
Well the leak/wear must be considerable if the linkage won’t lift at all when the oil is warm. If you take the side cover off (right hand side of transmission housing under the seat) and run the tractor (DON’T PUT YOUR HANDS INSIDE WHILE THE TRACTOR IS RUNNING), put the position control lever to UP. Look inside for any obvious leaks – particularly the stand pipe or lift cylinder. If there is a leak then you will be able to see it (if the lift won’t raise at all). If there is no leak then I would remove the top cover (the large piece under the seat) and remove the pump. It is possible that there is problem with the relief valve (can be replaced through the side cover without removing the pump), but more likely it will be the control vavle which will need replacing , or the pump components, or the vavles (in that order I would suggest). The method for assessing these components is shown on our Hydraulics DVD.A full repair kit isn’t too expensive if you don’t want to go through the process of replacing individual components, putting the whole thing back together and then finding that you have to start over again as you have replaced the wrong part!
Hope that gives you some ideas.

WE had the same problem with our Massey 35. After several rebuilds of the hydrallic pump – acouple of times by us and once by the dealer – we discovered the valve body for the controls _ the handles between your legs _ had begun to wear out. Either rebuilding the valve body or replacing it will cure the problem.
Hope this helps.

Hello David We have a massey 135 that we have been working on for a week We had a broken cylinder in the hydraluics after changing the cylinder we lifted it and it broke the studs right off We have gone forward We now have it so it does not blow its brains out but it is right up to the max with no play in the lift arms and the piston seeeems to be at the max. how do we get the 1 1/2 play in the arms we should be able to pick the arms up a 1 inch or more after it has reached it max lift now it real tight no play in the arms and they are very high in the air. Thanks Doug
Massey Ferguson Hydrolic Lift will not go down with lever. Push in two speed clutch, it will go down. Let clutch out regardless of lever position lift goes up. Any Advise??
Hello,
I believe my pump is the problem and needs replacing. I flushed all the oil from the system and replaced it, but that didn’t help at all. I would like to get your video. Do you mail to the United States?
Thanks,
Barry
Hi Barry,
Yes we mail to the US. We charge the same postage rate to anywhere in the world, and we do a NTSC disc (US format).
