Looking at a mf 135 diesel, power steering is not working. Just looking for input on what could be wrong and how much the cost to repair and are parts available new. Thank you in advance for your help.
 
Could be the pump, the sector, hole in a line, seal blown, or simply a $2.00 qt of oil. I think we need a little more info to figure this one out.
 
It would help me if I knew the worse case scenerio what the expense could be. Guy who has the tractor said 200-500 worse case at the massey delership but I wanted to run it by everyone here to get some feedback.
 
MF 135 power steering systems can be expensive to repair depending upon vintage and problems.

Since you are asking for a worst case scenario, figure on $2000 if you hire a dealer to repair it and it needs both cylinder and gearbox rebuilt and a pump. you will not get much 135 PS work from a MF dealer for $200-$500.

$200-$500 won't get you very far. I spent almost $400 in parts alone plus a full day of working on it changing the power steering cylinder. It's a real bear to get to. Mounted under the battery and bolted to the steering gearbox. NOT a fun job!
 
We need to know where the MF-135 was made. Power steering on a UK MF-135 doesn't even resemble power steering on a US MF-135. UK has a cylinder pushing a drag link, US has a cylinder on the front side of the steering gear.

My US 135 broke, it was the piston rod. MF dealer in about 1994 wanted $472 for the cylinder assembly, parts not available. I bought a seal kit and took the remains to a local machine shop. For $125 he carved a new piston rod and piston and honed the cylinder and repaired the steering column where I'd broken out a bit working too hard on the top seal. Bill was $125.

But it could be the pump, the oil supply, the filter, the hoses, the valve (that works on a bit of end play in the steering shaft), the rack that the piston moves over the top gear, or the top of the gear box split out from the pressure of that rack, that is if its the US version. If its the UK version, I don't know what it takes, but it could be most of the above as well as both could have bad piston seals in their respective cylinders.

The tractor is a USA model, no cylinders on the tie rods, lines go from pump to steering column. Thanks for the info. I wanted to prepare for the worse case to decide whether to buy it or not. I appreciate the help.
