140 Steering Question

Postby tst » Sat Jul 31, 2021 9:16 pm

have a 68 140 , the steering wheel has to much play but other wise works fine, was looking in the service manual and it is almost useless tells nothing about adjustments, just a couple pages for the whole steering section, anyway I do see a spring on the steering shaft, could that maybe be what is suppose to take up slop? do not see any adjustment in the picture of the steering box apart, anyone familiar with this setup ?
thanks Tim

There are no adjustments. Make sure the bearings are good, replace the bushings in the steering box, and make sure there is no movement between the center pitman arm and sector shaft, and the sector gear and sector shaft. Most of the time, the keyways on the sector shaft are the main causes.

I don't know what spring you are referring to, unless it is high clearance or has the heavy duty axle. In that case, there are springs for the axle stops.

There aren't a lot of adjustments. Look for sources of play the same way you do on a Cub. The big differences are that there are bearings in place of some bushings, the worm wheel is a sector and not reversible, and the vertical play of the worm wheel shaft is controlled differently.

The worm wheel shaft has a ball bearing at the top. The shaft is held in the bearing with a snap ring. The bearing is held in the housing with a retaining ring and 3 cap screws. If you have vertical play, either some part of that has come loose or (more likely) the bearing is bad.

thanks, for the tips, in the factory IH manual I have it shows a coil spring above the lower seal, was trying to get an idea before tearing into it

That is probably the axle stop spring and the drawing just makes it look like it is above the seal.
