Steering arm removal

Postby RanchsA » Mon May 16, 2016 8:04 pm

Hi all. Starting into the steering box on the A. The vertical shaft had up and down play so I'm guessing I'll find the bearing gone at the top which was causing my 2/3 turn of the wheel before any action. I have the kit from Steiner on the way. But having a time getting the arm off the shaft. I can't get a puller on because of the lack of room. Is there a trick to this I'm missing? Mine doesn't clamp on like the one in my parts manual but looks like it presses on.
Thanks
randy

You're talking about the steering knuckle right? with the two ball and socket joints? Do you have the lower steering housing removed from the bolster? If not your best bet is to remove that and use a rubber mallet and hammer the shaft up.

The later style Super A had a pressed one and not a clamp/bolt.

You could also try using a ball joint separator.

In any case, you will need to remove the front axle.

I also like the the ball joint separator idea from Mike. Basically a double wedge, a couple whacks with a persuader.

I do have the axle off and the bolster bolts removed it wasn't wanting to let go either. I was thinking I could slide it out and it moved about 1/2" and stopped. Didn't want to try and force it to hard because I have a habit of breaking things when I do that. :oops:
I'll definitely see if I can persuade the bolster to let go. I'll be sure to try the ball joint separator as well, if I can't get them to separate. I was trying to think what I could get in between there. I have the motor assembled and painted and should have my radiator showing up this week. I have the clutch waiting (pilot bushing must've taken the long route in the mail) to go on. So once I get this apart and cleaned up. It should hopefully be some smooth sailing with re-assembly. I've been pretty lucky this is the only part that has really given me a hard time as far as disassembly.
Our tool bench is carrying a lot of the same tools right now EZ. he he he
Thanks Mike and EZ.
Hopefully my next post is a picture of the garden getting turned under.

Well the top isn't wanting to separate from the bolster Separates about 1/2" and doesn't want to go any further? So I tried the ball joint separator. I think I should have used more patience... :oops:

OK so you broke the separator? I hope that is all.

Did you cut the axle pin?

Put alot of heat to it. I hammered on it with the air hammer and whacked it with the threaded rod. It will let go.

Yep the separator handle snapped off. At first I thought cool it came free when I felt the handle loose. I'll have to see if I can find a blunt ended tip for my air hammer. I feel like the ones I have will damage that shaft. I used the handle to drive the wedge in nice and tight to keep pressure on it and gave it a good shot of penetrating oil last night and this morning.
Yeah I cut the axle pin. One of the previous owners must've had an accident or a hard time getting it apart. The bolsters front clamp was gone and that end of the pin was welded in place. I have a "new" bolster and pin on the way.
Any ideas as to why the top housing won't let loose?

Here are a couple images of the housing apart.
Is your steering wheel shaft still installed? Could be catching up on the gear sector.
Also I remember having to fight the key out as the seal would not clear it to pull the bottom of the bolster off.
I think the shaft is 'held' to the top of the bolster with the bearing retainer. Once you have the arm off, you remove the key and the whole bottom should now slide out. Then you remove the bearing retainer and the shaft and bearing will drop down.
Good luck.

Read this a couple times. That is the way is should come apart. The whole thing will not come out as a unit.

I had to use a two jaw puller and a torch. Crank down on the puller until it is under pressure and then heat the arm where it wraps around the shaft. I ended up taking to a guy with a ox/acetelene torch, a plumbing torch will not get it hot enough.

thanks for the responses guys. I pounded on it for another hour last night. I only have 3 jaw pullers they are too big to fit between the bottom of the knuckle and the bolster. Do the two jaw ones have smaller grips on them? I noticed EZ had a set on his bench as well.
I pounded it on it for another hour last night and no luck. This morning I decided an acetylene torch was my next move. Figure I'll get the broken end of the ball joint separator in there and get some good solid pressure and get her real hot. I'll be sure to post a victory picture on here when it does finally give up that grip. :D Memorial day is my typical put the garden in weekend so hopefully this thing comes together between now and then.

I saw a video of someone who said they used a cheap 2 jaw puller. (Below is a photo, don't be that guy that tries to click on it haha)

Ha ha ha, almost did at first. I actually watched that video this afternoon and bought that same puller. I'm thinking that guys knuckle had wandered down on him. There isn't enough gap on mine to get it around the base. I've even ran it through my wheel grinder a bit to try and fit it. I'm afraid if I take too much more the fingers will break off when they get pressure on them. I don't have to work tomorrow so I'm going to get the acetylene out and get him some real heat. I can get some pressure with my half a ball joint separator still. I'm hoping with some real hot heat and that in there I can maybe separate it enough to get puller on and finish the job. See if I can weld my two piece separator back together too. He he he

It is a tapered fit so once it frees up it will just pop off.
