John Deere A Steering Adjustment and 3 Point Hitch

- I try to fix my wobbly steering but am unsuccessful. I will need to look at changing out parts with less wear. But I "fix" my 3 point hitch by adding oil to the reservoir.

There's 3 steering adjustments you can make.
Up & Down: Jack the front wheels off the ground. Zero a dial indicator on the nut holding the sector gear on. Next lower the wheels back down and read the measurment. Cant remember the spec but its next to nothing (Maybe .012). You can make washers or shims to go under that nut to take up the slack.
Side to Side: With the fornt wheels off the ground adjust the ecentric until you can go full lock to full lock without binding (The groainng noise you heard when trying to turn). This was the adjustment you attempted but your problem lies in the next adjustment.
In & Out: Take the front bearing cup off and remove shims until you virturally eliminate being able to see the shaft screw in and out (The shaft should stay pretty still and not screw in and out of the pesestal much). The manual calls for a spec of maybe 1/2" but that awful wishful 75 years later. You may get down to about 2" of play at the wheel.
If that doesnt help the issue then a new sector gear (Steiner, etc) or worm gear (Usually theyre fine unless the have been run loose long).
Yes, after I made this video and failed, I went and read the service manual which specifically states you start with steering wheel shaft "in/out" adjustment. Next is up and down freeplay of the vertical steering shaft. And then last you adjust the eccentric bushing. I skipped over the first and second. But I'm planning on checking those and hopefully can come out victorious this time.
Another great video. I love watching 👀 you and your dad work on your John Deere tractors
Thanks 👍
I hope you get your steering issue figured out.
The old A sounds good. I love the late A’s.
Thanks!
Try packing your steering gear box with sock grease , like is used on the old beet harvester knife gear boxes . That will help shim up the worm and the gear . Also cover that P.T.O. shaft , so that it doesn't eat you up !!!!!
Thanks for the advice!
I put corn head grease in mine last year and it has leaked out the front cap where the worm gear cap is. It might need new gaskets but I know it’s shimmed. You might be able to take a shim out to help out with your play as well. Worth a shot. I don’t think grease will fix the amount of free play it has.
Good to know about the corn head grease.
We have a couple of parts A's, so I think I'm going to look at the steering sector gears on those and see if there is noticable wear on any of them and try to swap out to the best gear... Maybe that will help? I figure it's worth a shot.
The sock grease is a combination soap and grease . I'm not sure if JOHN DEERE still carries it . Amazon may have it , they have everything ..
I've never heard of soap and grease... But I have heard of detergent oil. I wonder if there is a detergent grease too? Although... Not sure what a detergent grease would do.
Not sure about later models, but my 46 A had 90w oil in the steering gear box. Lower bearing wore out would not hold oil. Need to check end play of the vertical shaft. When I checked mine I had 1/2 in vs spec of .03. If that lower bearing is worn, the sector gear and and worm are misaligned resulting in more lash. I replaced the lower bearing, cork gasket, upper packings. Re shimmed to spec. Holds oil and steers alot easier when everything is back to spec.
Thanks for the advice!
I have adjusted my 43 A’s steering free play to 2 to 3 inches at the steering wheel…couldn’t go any tighter because the sector gear was on its last slot. The worm gear is welded (?) to the steering shaft, so not replaceable on its own without fabrication. I could not get my sector gear off its spline using heat and a gear puller so gave up. I believe that the steering gear “box” is supposed to be filled with oil, not grease. BUT, in my case, the oil leaks out the bottom. That’s why I tried to pull the sector gear so I could replace the seal. Now I use grease.
It'll be interesting to figure out what the main contributor to the freeplay is... Worm gear, or steering sector gear or worn bushings at the eccentric. Hopefully I can get it sorted out and to the point where I only have 2-3 inches like yours.
Nice tractors.
Thanks 👍
I got mine out this summer and my steering was fine and now I can barely turn it with two hands - I don’t know what happend please help I need advise
Steering can be very frustrating. I'm still in the process of getting mine sorted out.
That pto is an accident waiting to happen
Yes, safety was secondary on these tractors. But on that note... a pto shaft is an accident waiting to happen on any tractor if you're not cautious and constantly aware.
