There are three parts to the MF-135 power steering system. The pump is gear driven by the camshaft gear chain. There are NO brackets. It has the reservoir built onto the pump. Its not so small to be hard to find. The steering cylinder is in front of the steering gear box directly under the battery. Its about 4" inside diameter and about 4 or 5" stroke. Its not there on a tractor without power steering. It runs a rack against the top cross shaft gear. If worked hard the rack pushes up on the top of the steering gear box and can split it. Mine broke the piston rod and then beat up the piston cocking it in the cylinder bore. The local (when there was a local) MF dealer wanted $472 for the cylinder assembly. A nearby machine shop removed the piston saving enough for accurate measurements, carved a new piston and piston rod, and fixed a broken seal seat in the control valve for $125. A previous owner had welded braces to the top of the steering gear box cover to hold the rack down. The new parts have been running for years now. The third piece is the steering control valve on the steering wheel shaft. It has the hoses going to it from the pump. The shaft is allowed some end play and its that end play that operates the valve. I have seen MF-35 with a power steering tag on the steering wheel but without most of the parts. if you really want to know the options and what you have, you should own the owner's manual that covers the serial number range you have (the manual is a great deal different for those vintages with the Continental gas engine compared to those with the 3 cylinder Perkins gas engine), a copy of the MF 135 parts book, and a copy of the I&T shop manual. The I&T manual isn't complete but its better than nothing and far less expensive than the factory service manual. The last CD service manual I bought on epay, covers mostly MF-148 and doesn't resemble my 135. Gerald J.
