130 steering worm (pics added)

Mon Jul 23, 2012 7:37 pm

Guys, The 130 manual, and the archives tell me that the steering worm and shaft should come out of the housing by turning it (clockwise) and forward, actually coming out the front of the steering box. That is, after the bearing retainer and castle nut have been removed.
Trouble is, the bearing may be seized in there as it will not budge. About a pint or more of water came out, followed by gear oil when the retainer was removed. Not sure how I"m going to get it out. I want to correct the steering slop, replace seals and bearing if required.

If the bolster is still on the tractor and you are working alone, place plenty of cushioning under the area (in case the gear falls out) and turn the steering shaft (the shaft that the steering wheel is on). That should help move the gear.

Bus Driver,
I can see the bearing.
I'm guessing that the castle nut could have stayed on if the bearing is to come out with the shaft.
Also guessing that the bearing is pressed on the shaft. I can't see any rust.
If I turn the steering wheel shaft all the way right, I reach the end of the travel for the pitman arm. After that, it feels like I might break something if I force it any further.
Funny thing is, everything in there seems tight and moves perfectly together without the axle and wheels attached.
I'll have to leave it a couple days, going on a road trip.

Makes sense that the ball bearing (ST287) should be snug in there, are they always a bull to get out?
The way the manual explains it, it should just come right out.

Thanks for the reply.

Not suggesting that the shaft be forced beyond the natural limits, but that rotating it back and forth slightly may help work the gear out.

Hmmmm...that bearing on the steering wheel shaft is froze in there. After cleaning the area I can see some rust on the lower portion of the bearing.
Wondering now if I should just remove the big nut on the pitman arm, drop the lower half of the steering unit. This should bring the worm gear out.
Then I'm sure a few taps on the steering shaft should bring it, and the bearing out through the front of the unit.

Again, the manual says it should just come right out.

Note: I tapped on the steering shaft up at the steering wheel end and now the bearing is still stuck but the shaft moves in and out of it about 1/8".

The steering gear ARM is froze on the shaft as well.
Found a 1" 5/8 socket (that's a big one) and removed the large castle nut holding the arm on. It was a bull. Had to put a pipe on the wrench.

But, the ARM will not budge. I suppose some PB Blaster is in order, and maybe some heat.

As I recall, that shaft is tapered. When it lets loose, it will come all at once!

Thanks Jim,
I got it cooking in PB Blaster now.

For steering arms on tapers, a puller tightened up well and then tapping on the outside of the collar portion of the arm usually pops them right off. I would not use heat.

BD,
I left a puller on it overnight.
At some point this thing will eventually pop off.
I can feel that there is something wrong inside.
Tapped on the arm sideways with a rubber mallet, it moves about 1", but the steering rod is not moving, so something is broke inside.
That would account for the 3/4 turn on the steering wheel before the wheels even started to move.
So...............Gotta get this thing apart and investigate.
Paint will have to wait.

I doubt anything is broken in there, I expect it is just wear.

The center steering arm may require a fair amount of "persuasion." Don't go crazy with it or anything but I would not be afraid to get a little "rough" with it. If it was me, I would cinch the puller down nice and tight, put on eye protection/gloves, get a good big hammer and a big punch and wail on the sides of that center arm where the shaft goes through a time or twelve. I bet after a couple good sharp licks it will fall right off. Once you get it off, drop the base of the steering gear housing, and you can see what's going on in there. I am thinking since you can't get the worm shaft out easily it probably has never been apart.

SA,
Thanks for the reply.
I left the puller on overnight, soaked it good with PB Blaster.
I gave the puller another turn this morning so it was cinched up nice and tight.
Then I used my air hammer with a flat snub nose on it to 'agitate' it. Hammered on it for quite awhile on the sides, up onto the bottom, and all around.
It won't budge as of yet.
I can see that the woodruff key is on the forward part of the arm. Might try hammering on it a couple times with a 'point', but I don't want to mushroom it.
Also tried some heat, hoping it would 'pop' but nope. Think I'll look for a bigger puller. Not much room in there though.

Might have to resort to an adult beverage, a few cuss words, roll up the sleeves, and go in swinging!

I would have to say that the seals and gaskets are/have been pretty good to keep all that water in there all these years.
There was a good amount of gear oil as well.
