Hi there,
Have an Allis-Chalmers 160 and have a steering issue and looking for some input. We have the higher end model that has power steering.
My father reports that when he hits an obstacle with his tire the tire will turn and he won't get any feedback in the steering wheel (understandably from what I gather).
From what I can deduce, the issue is either in the power steering valve box with the spring being shot or the nut overtightened so that it's letting oil bypass. Not sure if that's how the steering valve operates though. The other place would be in the hydraulic cylinder that controls the steering and that feels like the more likely place.
Does anyone have any thoughts / suggestions before we tear it apart?

Suggest you have air in the system. Can't compreess a liquid. Else the cylinder packing is blown on the piston. No hydrostatic steering will 'kick the wheel' as in a manual system. There is no steering box on a 160. There is an orbit motor similar to all others in the industry. You should be able to turn the wheel lock to lock and hear the relief squeal. A leaking seal around the shaft will injest air in the system. Be careful about tearing down anything on a 160 - parts are a bear.

Have you replicated the issue? Is the steering hydraulic ram moving when this happens? It may be the steering orbital if all of those components are moving correctly. Check hydraulic oil level first before you proceed any further. It powers the power steering and the hydraulics on the tractor.

Like Tbran said, parts are hard to come by for these tractors. The steering, hydraulics, remotes require clean, air free hydraulic oil. I would check the level first. Is this a One Sixty or a 160 tractor? Early version being a One Sixty. Later version is a 160. There are differences between models so let’s verify what you have first.

Once the transmission fluid is full and filters are clean, the power steering is self bleeding, turn steering all the way to the right and then all the way to the left. It may take several cycles, as long as the orbital is good and you have no leaks it should self bleed.
