Hi
We just bought an old allis chalmers grader.
Not sure how to identify what model it is.
Could be a AD or DD perhaps.
Can anyone tell me where I can locate power steering for these old models?
Thanks
Steve

If it is a D or DD grader there should be a serial number tag on the frame just ahead of the front drive on the right side if you are sitting in the seat. The serial number would start with either a 'D' or a 'DD' and from the number we can determine what year it was built. I do not know much about the AD graders. I also don't know when they started listing power steering as an option for these machines. My D grader is a 1959 and power steering was not an option then. I have fabricated my own power assist system and I can turn it lock to lock with one finger even when it is not moving. A little more information on exactly what machine you have would be a big help.

It appears as though the tag you are refering to is missing. After looking on google images, the grader may be a D or DD. When I get a chance I will post some pictures. |

Your steering sounds great by the way, was it very hard to do?? |

The AD series are full size graders and should have a Detroit Diesel engine.

I will try and post some pictures of my power steering installation. I have not posted pictures for some time and I have to reacquaint myself with the procedure and I am just too busy at the moment. I will try to have them posted by the weekend.

Thanks for the info. Our grader is not full size and does not have a detroit diesel. |

I have found that if you have the "slant wheel "option , can steer better by leaning wheels to the direction of travel . Give it a try, CC

The steering gearbox on this grader needs a total rebuild. If you don't lean the wheels when turning, the steering wheel just spins. Not freely of course, but the gears jump. Can't see the point in trying to rebuild it, and still have heavy manual steering. |

To begin it seems as if you have either the D grader(gas) or the DD grader(diesel). It also seems as if you have the leaning front axle and not the rigid front axle. The leaning front axle makes the conversion a little more difficult because there are two drag links and no tie rod. When I added ps to my grader I joined the two drag links together to form a tie rod.
You essentially have two options, power assist where you still maintain a mechanical linkage between the steering wheel and the front axle or, hydraulic steering where you have a control valve on the steering wheel and the steering is done by hydraulic cylinders connected to the front axle. Regardless of which system you use it works best if you use a separate power steering pump. A D grader owner near me replaced his steering box with the ps box from a pickup truck. He moved his main hydraulic pump to drive off the end of the crankshaft and installed a belt driven ps pump where the main pump had been located. I did something similar with my hydraulic pumps. My steering box was fine so I acquired the drag link control valve and hydraulic cylinder from a Cockshutt/White sp combine for my ps components. If you wanted to go fully hydraulic steering you could go to a farm equipment salvage yard and get the steering wheel complete with control valve and steering cylinders from a sp combine. I paid $75 for the power steering components and another $25 for an old ps pump.
