mf135 power steering

regulater · Jun 27, 2015

Hello everyone, need a little help with my power steering.I jacked the front up so I could turn the steering wheel easy to bleed the air out. every time I turned steering back and forth a few times and checked fluid it was low. I could not see any fluid leaking. I put about two or three oz every time I checked it. when the tractor is setting still it has no power steering, when its moving it turns good to the right and not to good to the left.

It takes time to bleed this system just keep adding oil and rotating wheel stop to stop let sit a while do it again

thanks traper, Ive filed it about eight times. I'm wandering if the fluid is going in the motor.

If your oil looks foamy you still have air in system. IS your crankcase gaining oil?

Yeaaaaah... leaking into the engine oil is a sad but common problem. If you pour in a pint? Still doesn't cure it? doesn't leak on the ground? ... then you need seals at the gear shaft...

oil don't look foamy and i didn't check the oil before I started. I don't see any red in the oil but I guess the oil would turn it black. I know I need to change my oil.

If fluid is leaking in to oil would that cause the power steering not to work good even after i fill it up?

I pulled the pump and put a seal and new filter. the tractor turns to the right great but still hard to the left. can anyone help me with this. thanks

Does it still hard to turn to the left with the front wheels off the ground? If it still does you could unhook the drag links, and turn each side buy hand (you may also remove the hoses from the cylinders). While the drag links are unhooked with the engine off turn the steering wheel both ways to see if its still hard to turn left. On tractors used in fields right hand turns are used a whole lot more than left turns (the sector gears get worn over time). So if someone adjusted the sector gears in the steering box to take some of the play out the left turn from straight gets tighter than it does on right turns (especially if they concentrated on getting the play out on right hand turns).

thanks ptfarmer, with the wheels off the ground it turns great both ways, with wheels on the ground sitting still it's very hard to turn either way, when it's moving it's easy to the right and hard to the left but not as hard as sitting still.one man told me that the cylinder will push to the right but if the pin or the rod is broke it won't pull the piston back while turning left. I don't know if you can check it with out pulling all the gears.

The 135 has two different power steering setups, one has big cylinder on the front of the steering box, the other has two small individual cylinders, one on each side that connects to the steering arms on the front spindles. Which setup do you have?

On another note the 135 power steering setups are not the best designed, and rarely work like they should. My 2135 industrial (practically the same tractor as your 135) had the 2 small individual cylinders, the steering was hard to turn both ways with the wheels on the ground. I took all the power steering stuff off my tractor except for the control valve in the steering column, and it still steered the same so mine wasn't working at all. The 135 power steering can cost a lot of money to fix that's why I just took mine off (to fix mine I would have paid more to fix the power steering than what I paid for the tractor (which was $1500.00). Plus my tractor doesn't have a front end loader so the manual steering is not too bad.

mine has one cylinder

ptfarmer · Jul 9, 2015

I would un-hook the two tie rods going from the steering arms to the front axle to see how the steering box itself feels (tight, and or loose spots). The steering could also be tight if the bushings, and thrust bearings on the spindles are worn-out.

well I tore my tractor down and pulled the steering cylinder off and the rack on the cylinder rod was broke, thats the reason it would not turn left.my problem now is the gears have to be timed and I can't understand how my manuel is telling me to do it. can any one tell me how to do this. thanks

I wanted to bring everyone up to speed on my tractor. I put a new rack and rod and all new seals in the steering. got it back together today and the steering works great as long as the tractor is moving just a little. if its sitting still its hard to steer either way. is this normal for a mf135. thanks

ptfarmer · Aug 6, 2015

With the tractor sitting still did you try it with the engine idling, and then try it with the engine revved up? if not try it, and see if it feels different. Does your tractor have 4 cylinder Continental, or the 3 cylinder Perkins?

regulater · Aug 6, 2015

thanks for the reply. I tried it with the engine rived up and it turned a lot better. the engine is a 3 cly perkins diesel.thanks

I don't know if all the single cylinder MF135 power steering setups are that way. I have yet to see a 135 with power steering that hasn't never seem to work perfect, but with revving the engine you increased the flow, and pressure output of the power steering pump. You would need a inline pressure gage to see what the pressure is, that pump is probably at least 40 years old, possibly a lot of hours on it, and the filter in them don't get changed much if at all.

On another note I took the power steering of my tractor because it needed all now hoses, and at least one new cylinder. Afterwards it still steered the same without the power steering on it.
