UTU Steering Worm Bearings

Anybody have any good ideas of how to restore the steering gear worm shaft on a UTU? The steering worm bearing surface on my tractor is shot.

The bearings seem to be obsolete [JT9202,JT9201]. Can"t find an interchange or even any bearings like it in the Timken catalog. Tempted to turn the shaft down so that a standard tapered roller bearing will fit. The problem is that the O.D. of the original bearing cup (Timken 32-C) is an oddball size. I would probably have to machine the adjusting plug and the front casting to hold different bearing cup and I don"t know if that could even be done.

I haven"t checked, but I hope the standard bearings and cups are available from agco. Are they? Altho that would still leave me with a steering worm with bad bearing surfaces.

Just hoping somebody has a good idea to fix this problem with modern, obtainable bearings. This is a work tractor, so looking for something that will hold up.

TIP OF THE DAY-- The front steering gear box on those UTU"s were a horrible design. Water gets in, and pushes the oil out. On my other 2 UTU"s I drilled and tapped for a petcock drain in the front lower portion of the steering oil resivoir. Once every couple months I open it up and drain out a table spoon of water.

Thanks for reading, if any body has any suggestions I would appreciate it.

I know 10 years ago I had a bearing house look for those bearings. At that time they were $100 a piece. I found some used ones in my stash that were OK. The next time I will get standard taper bearings & do as you said.

I think I have a couple of good worm gears. Also have the sector gear that mates with it. If interested. In north Ill. Send me a private PM.

Read this one

This was a post I made regarding installing a water drain in the bottom of the steering gear box of a Ford 4500 Backhoe.

the spiral on my worm gear and nut were OK but the ball races machined into the shaft were toast. I could have gotten new 3/8 inch ball bearings but had no way to repair the shaft so I went with an aftermarket nut and shaft from a aftermarket dealer in Winnsboro TX who imports them from Turkey. Have you searched the web for your part? Sometimes you will see them in the oddest places.
An antique collector in NJ was selling a similar one to the one I needed for 65 bucks or 3400 bucks. I guess that makes sense.
When I got the aftermarket part I still had to modify spacers and shimming bigtime and grind and polish the forks to get it into the original gearbox. The part I got was rough to say the least. I have also noticed very poor hardening on many aftermarket parts even ones from "reputable" sources.
