Farmall cub lowboy steering problem

My Dad have a 1957+- cub lowboy. The steering is a bit sloppy in the gearbox and it seams to steer alittle hard. I lubed the busing right by the steering wheel and it seemed alittle better but still not like it should be. You can move the steering wheel before the wheels turn. It has been greased and we did jack the front end and tried the steering. The front seemed to be OK. Is there an adjustment in the steering gear box? He has two plugs in the box just below the filler plug. Hope I kinda make sense.
 
This system is typical of smaller Farmalls. It has a Worm at the bottom of the column in the box. and a sector cam that has a stud that
sticks out into it. to turn the shaft. There should be 90 wt gear oil in the box, but it often leaks out. There is one plug, and one
adjustment screw. Part 6 is the fill plug, and part 13 is the adjustment screw. The bearings shown are angular contact ball bearings. I
would clean out all old lube, and fill it with what is called corn Head grease it is a semi fluid grease that won't run out as easily.
Farm stores, IH dealer, or JD dealers will have it.
The bearings can be looked at for roughness, or looseness, and adjusted with #5 nut (IIRC) they should be just snug without play, not
tight. The adjustment can be played with a small amount to push the stud farther into the cam, but it might not take more than 1/2 turn
before it starts to bind, be cautious. If the stud is worn to a nub, it could be welded back to bigger and ground down to tighten the
steering. A welder Fabricator job. Also be sure to check the thrust bearings in the steering spindle shafts (different page same source)
to assure easy wheel turinig. Jim

Jim that is not the gear box he has. This pic is one like his. We did put some 90wt in the box and the box doesn't appear to leak. Hope my image comes through.

Jim just got off the path a bit, this one looks like what you
have. Unfortunately like many of the Farmall row crop
tractors your box does not have any adjustment. If you
want it tighter you have to tear it down and replace the
worn parts.That is if they are available and most of it will
need to come from aftermarket sources. Using the diagram
and having the parts numbers to search for them is very
helpful. On another note if you would like some manuals for
your machine send me an email and I will send you a link
to them. Best of luck!

The first step in tightening up the steering is to do a close examination to find where the slop is. A lot of times, there is just a little in many places that adds up to a lot. Ones like that can't be helped much without quite a bit of effort. Some of the places to look:
In/out motion of the input shaft -- easily helped with new bushings or adding a thin machine bushing.
Up/down of output shaft -- easily helped by adjusting the castle nut on that shaft.
Slack at tie rod ends -- sometimes helped at outer ends by adjusting out the slack. Sometimes helped at inner ends by removing shims.
Slack in worn gears -- often helped by rotating the sector gear 1/2 turn to use the previously unused part of the gear.
Movement of either shaft in other directions usually require new bushings. Do new seals at the same time.

There are more details to any of these fixes. First step is isolate the problem.
 
If you go to that (CaseIH) site and search for "LOBOY" I think all you will get is the catalog for the numbered Lo-Boys (154, 185, 184). To find the earlier offset Lo-Boy parts, you need to look for "CUB". The offset Lo-Boys are in the catalog with the Farmall Cub.

The offset Lo-Boys were built until 1968. Then it was replaced by the 154.
 
Thanks for the replies. I went to the CASEIH website and could not find a parts illustration for that gearbox. If someone has the link to that diagram that would be appreciated. I think I may wait till this winter and open up the box and see what we have. He can use it as is for now.
 
Most of our 9 cubs have a bit of slop in
the steering. Haven't dug into any of
them. Doesn't bother us. Have filled the
steering gear box with corn head grease,
won't leak out. Open bottom plug and let
old nasty grease drain out. Then fill.
 
The slop he can live with but it does seem to bind alittle. The box doesn't appear to have any leaks. Do yours have the same gear box as his?
 
FYI, the regular Cubs and Cub Loboys prior to the 154/184/185 are built all the same except for the front axle knees
and spindles being shorter on the Loboys. On the Loboys, the final drive is rotated a quarter turn to set the chassis
lower.

Go back and reread the post by used red MN. It has the link to that parts illustration.
