I am looking at a 1961 MF 65 with a gas engine and power steering. The power steering works for right turns, but not for left. Anybody seen this before? Are power steering parts avail. for this beast? Thanks

I also own a 65 gas. When I bought mine it only turned one way ( I don't remember which way ). My problem was very simple. Under the front end where the splined vertical shaft comes down from the power steering, the compression linkage around the shaft slipped down and was impacting the frame when turning in one direction but not the other. I moved it up and retighten, worked great. It could also be adjustments as others described.

Good morning.

The folks below have good points - wear might be a problem.

The first step, however, would be to check the turnbuckle connecting the linkage to the control valve. It moves the control valve in and out in response to steering wheel movement. Located up front, horizontal, above the power steering cylinder and parallel with it. You will probably find that the valve is moving in one direction only.

The turnbuckle shortens or lengthens the rod until control valve travel is equal and the steering works equally in both directions. Loosen the nuts on both ends and turn the barrel 1/2 turn in one direction, move steering wheel and check valve movement. Keep trying, in both directions until you see control valve movement in both directions - you have the rod close to the correct setting.

You fine tune with the engine running, tweaking until the steering moves with equal effort in both directions then re-tighten the nuts on both ends of the turnbuckle.

Good luck!

Sounds like a problem with the adjustments or the linkage. Check to see how much play you have in the linkage at the power steering cyl. You have an adjustment on the arm up front, it is a screw that is vertical, also the linkage between the cyl. up front and the steering arm. Also check for loose play at these points. If you have a lot of play you may need to replace the bushings in the steering pedestal housing.

Also check the control valve under the steering wheel. It may use a link and pin system. That is, the steering wheel when turned operates a valve up and down to actuate the cylinder. If the mechanical system has too much play it won't operate the control valve.

Thanks, I drove to a dealer and talked to there service dept. They gave me the same info. I've got a service manual on order. I am upgrading from a TO-30 to the 65 and I wanted to make sure I don't buy a bum steer.
