M151 Steering Gear Problem

[dabtl]

Has anyone rebuilt a M151 steering gear? Where does one find the internal parts?

Are the A1 and A2 steering gears interchangeable?

Does anyone have a nos they will sell?

M151 and M151A1 are the same but A2 is different. To change to A2 you need to change the column also. Can't help with rebuilding.

Thanks. David has a real mutt. It is wired with an A2 loom and has an A2 engine. I will have to figure out which steering gear it has to know what to buy.

As a thought, does the install of the A2 gear box and column into an A1 require more than the two assemblies you mention?

I find A2 gear boxes plentiful along with the steering columns. If they interchange easily, perhaps that is the way to cure the problem?

Found a NOS M151A1 steering gear box. $195. Thanks for the information on this.

That sounds like a good deal. I have a bad one that I took off my body I am restoring. I am planning on using the good gear out of my donor vehicle. To answer your other question, I think you need to change the steering wheel also but I an not sure. Everything else is bolt on.

David informed me this afternoon that the steering wheel had to be changed also.

But, thanks for the help. Any information here gets used at some point.

You can put A2 steering gearbox and column on an A1 no problem. Acctually this is a suggested "mod" as it is easier to service the gear. I think the pittman gear will interchange but not the column gear.

I rebuilt mine, the -34 has it all. I got the seals at a local Bearing Distributors.

Very relevant to my interests...I am working on fixing an A2 with about 20 degrees of steering wheel backlash. The tie rod ends are tight with no play. I feel all the backlash is in the recirculating ball gear box and can feel the ball plates crash in the case. It appears to have the same adjusting mechanism (lock nut and slotted stud) as any other manual gearbox I have worked on...downloading the -20 just to do it right. And also get the alignment specs to do the job perfect. Steering is critical in these vehicles.

Got it adjusted. Snap, all it takes is an offset standard screwdriver and a 3/4" box end. Jack the front end up so rubber is off the ground. Remove port wheel, then loosen the nut. Screw the slotted stud in until tangential force needed to turn the steering wheel is 1 to 1-1/2 pound. Use recording fish scale. Hold slotted stud and tighten nut.

I'm in Denton and have a 62 m151. Have been restoring for two years. Finally running but backfires and bogs when shifting from 2 to 3rd. Coil good, fuel pump good, timing good, carb rebuilt. Any words of wisdom?
