JD A Questions

Been looking today for an 'A' Service manual for new project. Can find Parts and Operators, but not Service, either through this site or JD's. Any ideas here?

How do you get the steering shaft out to take the hood and tanks off? Do you have to back the shaft out of the gearbox? How is this done? Is there a worm gear on the end? Maybe too big to come out through the hole in the hood? Do you also take the steering wheel off to pull that end through the hole in the hood?

On a compression test, what kind of readings would you expect?

As always, all help and comments appreciated! dwm

Hi, DWM, The steering shaft will not fit through the hole in the hood if you pull it out backwards, because of the retainer nut bearinr and worm gear are to large, as for the service manual the I&T manual #JD-4 covers models A,B,G,H,D,M&MT. I used this manual quite a bit when working on my 1940 A. Good Luck Ron.

Deere never published a service manual for the A. They did for the B and the tractors are pretty much the same.

Thanks for the responses.

BobC-For the service manual, I wasn't sure whether I & T or JD was the way to go, or maybe there are others. I'll keep looking.

dwm, I think Zane was thinking of a Model 60 when he gave you his advise. The other guys are on the mark.

You're right. I was thinking of my 60. I stand corrected.

I disagree with zane too. I agree with Mike3, but you don't have to remove the grills. Just the nose piece.

Remove the nose piece.
Remove the steering wheel.
Remove the two bolts holding the bearing retainer from the front. Watch out. The bearing will fall out. It is still available from Deere for like $15.00
Now, spin the steering shaft out. There is a bearing just like the one in front of the worm gear, behind the worm gear. When you spin the shaft. The bearing might get caught up on the sector gear. Push the bearing back and off to the side of the shaft as you remove the shaft. Pull it straight out.

When you reassemble it. Be very careful that, that bearing is seated when you spin the shaft back in. It is a little tricky. But I know that you will get it.

Any more questions, just ask.

I beg to differ with Zane's post below. To remove the hood take the stering wheel off then the cover on front of the hood, ahead of the radiator cap remove the grills, you can acess the front bearing quill from the front to get the steering shaft out turn the shaft to screw the shaft out it will come out the front.just start working on it &it will be obvious.

Mike Take the stering wheel off, be sure to take the woodruff key off the shaft. Take the medallion, some people call it the nose cone cover, off. Then remove the stering sector cover, then the bearing housing from the front of the sector housing. The bearing and race should come out with it. If the bearing doesn't, no problem it will push out when you start turning the steering shaft out to remove it. Once the sterring shaft worm is clear of the sector you can pull the shaft all the way out the front. I just did my A and that is the way it has allways been done on these tractors. Now as for the A maintenance manual I can't find one either. I have the JD manual for the B plus The I&T manual which covers a number of the 2 cylinders. Good luck.

If it's a row-crop A, there's a coupling on the steering shaft just rear of the sector. Take the grill off to get at it. The shaft comes out by moving it to the rear. Pull steering wheel and shaft.

Compression at cranking speed: All-fuel, 499000 up, 75; Gas 584000 up, 110.
