1951 B Steering?

dflippin08 · Dec 11, 2013

Good evening. Ive done a lot of searching on this site about the steering on my B. But I haven"t found exactly what Im looking for. I hope someone can and doesn"t mind helping me. I recently bought a B that was in the middle of a restoration. Im slowly putting everything back together. I just got the hood and gas tank back on it. I installed the steering shaft today with new bearings. My issue is that the wheel will only turn a couple inches and binds up. the bearins on the steering shaft don"t feel too tight. I think that the previous owner changed something with the eccentric under the sector gear. How do I adjust this?

You have the gears set to tight. They are most worn in the middle, so will bind on the ends.

Do I adjust this under the sector gear? With the screw and the notched ring?

David G · Dec 11, 2013

I have not worked on one for almost 50 years, but I am thinking you are correct. You would typically move the worm gear over with an eccentric.

It needs loostned up just a little.

Correct that, 40 years.

I will be 53 this weekend, had a 1951 B when I was a teen ager.

Yes that is how you loosen or tighten the lash between the two. Someone probably tightened up the lash with the front wheels in a straight forward position since that is where the most wear on the teeth is. Problem arises when you go to turn the wheel and it gets to the teeth that were not worn much and now you have no clearance and bind up. Turning the eccentric will pull the verticle shaft away from the horozontal steering shaft and loosen it up . Then you will probably find out it is too worn out and end up splitting the diff. and trying to find a happy medium. I have a perfect sector gear but it is B 1395 R which is for early styled "B" and late has different part # but I don't see any diff in them. Someone may be able to tell you whether they are interchangeable or not. New aftermarkets are $ 200 + and good used ones almost non-existent. I would sell this one for $75 if you find it will work.

The difference in the gears (B 1395 and B 2766) is the pitch of the teeth thus changing the steering ratio. This also pertains to the worm gear.
I make the gears.

dflippin08 · Dec 12, 2013

Thanks for all the info. Im gona remove the sector gear and see how worn it is.

dflippin08 · Dec 12, 2013

Cant I polish the other teeth on the sector to match the worn ones?

David G · Dec 12, 2013

No polishing, the gears are hardened.

I would adjust it so you can steer, then replace the gears if the slop is to bad. You can live with slop around the yard, but it is real annoying on the road.

Yes. Take the screw out and rotate the notched ring ( eccentric )one way or the other so as to move the gears farther apart. Don't go any more then needed to free it up all the way thru there travel.
Once set fill up that box to the bottom of the sector gear teeth with corn head grease. Regular grease is too thick and the recomended gear oil will be too thin on an old worn out unit and sure to leak out.

Make sure the the bearings haven't fallen out of place.

RandyB(MI) · Dec 12, 2013

Thanks for posting that , Rich, as I hate to sell something that doesn't work and now I know why. Yes , I have seen your ad on these and hoped you might be the one to answer the part # question. Thanks. RB

I took a grinder with thin blade and slightly ground the other teeth on the gears...very pain stacking work...but was able to get the gears to mesh completely through the cycle...then I adjusted gears together and was able to get all the slop out of the steering...if you got a lot of patience you can do it...need to work on both the worm and gear...on might make some sort of grinding type file....60-70 years of wear at work...
