Can't seem to find a steering sector shaft for 1971 CJ5

Hi everyone. My father in-law has spent the last several months restoring a 1971 CJ5. It is nearly finished, but he can not find a correct steering sector shaft. He has ordered a couple that were "supposed" to be the right one, but were not, and can't seem to find one anywhere. It's the 225ci V6 model and the shaft size is 15/16", he believes originally made by Ross. I've done numerous searches online and the only ones I can find are either for the 4cyl or state that it works for "all models, all engines"... which just can't be the case since they are different shaft sizes.

Would appreciate any information on this part, a lead, a part number, anything that help me find one. We need the sector shaft and bearings or a complete steering box.

Thanks in advance!

 

807478 sector shaft used with 808444 gear number
or
938194 sector shaft used with 936782, 941236, 943434 gear numbers
the part numbers for the two possible sector shafts

your is probably the 938194 larger diameter shaft

 

Have you looked here:http://www.jeepdoc.com/catalog/zproducts.asp?id=182 Looks like there's 2 sizes, yours is probably the discontinued one. May have to place a classified ad for one here. Good luck.

 

It does look like the discontinued one might just be what I am looking for. 15/16" and 2" on the pins. I did post a classified to see what turns up.

Thanks for your helpful replies!

 

If the pins on the sector shaft are worn, they can be replaced without finding a new old stock shaft.

 

yep

i was thinking about just turning the pins so that an unworn area of the pin would be in contact.

 

I have a new 938194 shaft and bushings.

From McRuff: "If the pins on the sector shaft are worn, they can be replaced without finding a new old stock shaft. "

Please tell us more! Where would I get such pins, I have the same problem finding a new sector shaft for the Barn Find.

No you can't buy the tapered sector pins alone.
But as I recenctly explained to another ECJ5 member you can often heat the sector casting to a dull red stage with your torch.
Rotate the tapered sector pins with a vise grip 90* then reswage the pins in position.
This fix works very well if the shaft portion of the sector is still servicable but the tapered pins have flat spots.

 

Ken,
Sounds good, thanks for the refresh of knowledge.
On my sector shaft it looks like the PO already turned the pins 180°. I'll try turning them 90°.
From the heat discoloration it looks like the PO heated the pins to turn them, not the casting.

Sure you can, most tractor dealers can get them. I replaced them about 12 years ago with John Deere parts, they cost about $12 for the pair. Remember this steering box was not designed simply for a Jeep, this box was used on all kinds of crap, forklifts, tractors, jeeps, and certain cars, there were 100's of 1000's of them made. They are also fairly simple to make from O1 or W1 tool steel, flame harden the working surface and then press them in and peen them over.

 

If anyone has a set of sector pins or the shaft with the pins in it that are worn but still have enough left to accurately measure them I will try to make a bunch of spares up.

 

Well that's good to know.
I meant to infer that W/O never offered the taper pins seperate from the sector shaft.

I have a NOS sector for the large CJ Ross (V-6).
Let me know if you want some measurements,
Only you'll have to wait a few weeks until I get back home.

Don,
It won't do a feller much good to turn the pins 180*

Myself I had good success turning the pins.
But I told another member how to do it and he stated his pins would not turn.
So I think he drilled them loose then welded the same pins back in.

 

On the one I'm replacing the shaft itself is bad...

 

If you can't find a good one the shaft can be repaird if its only gauled or worn and not bent.

 

kdem71,
Got your PM.
There were a few different models of the large Ross steering box in use.
Some were used for the MD's while others were used for the CJ5's,6's.
You should identify your particular Ross box.
Especially since your CJ is a 1971 vintage
(AMC use up the old stock while we can attitude)

There is a lettered number cast onto the side of the housing.
Please verify your box number. (not the cover number)

 

I'm the one that Ken helped. Like he said my pins would not turn when I heated the swage. I just ground off the swage, pressed the pins out, rotated just enough that the flats didn't touch, and welded them in. Working great so far, nice and tight!

 

Ken,
On further reflection, I think I misinterpreted the wear marks on two sides of the pins. After thinking about it, each pin would have a normal wear pattern for both left and right traverse of the front wheels.

It looks like the worst problem with my steering box is the sector shaft bushings. I got new ones on order from Krages, so I'll see how it works after putting in new bushings to keep the sector shaft from moving horizontally.

I have two of these gear boxes waiting for me to try and make one good one out of. I hope I can find this thread again when that time comes. Hopefully I'll be able to find it by checking my list of posts that I've made. I know exactly squat about rebuilding them.
