Case 300 steering worm gear tension setting?

Was looking into some excess slop in my steering gear box and noticed that the housing was bone dry! Should I just put 90W gear oil in it? Manual calls for SAE 140, never heard of it though.

Also, I noticed that there is a nut and a threaded rod with a flat tip slot in it, on the bottom of the housing. Looks like it can be used to tension the worm gear? I cranked it in and out but didn't see a difference, should I just crank it all the way in tight and leave it?

Complete parts book for the 310B loader and backhoe just came it today.....if only I could take the part numbers into wal-mart and fill up my shopping cart!

Thanks,
Ed

Although I don't know exactly how the tractor steering gearboxes are laid out, I did one on a '62 chevy I restored, and from that I can say that you better not mess with the screws on the outside until you know how it works on the inside. If you change the adjustment you are talking about... without knowing what it does, you might be tightening up the play, but be putting a major bind on the other components in your system or accelerating the internal wear. Steering gears are simple, but not many people know how they work...thus they adjust them improperly.

If your tie rods are shot, that's the first place you want to fix. A "little bit" of play times 4 tie rods= lots of slop at the steering wheel. I just broke apart my Case 311 (no power steering)& noticed that the fill plug on the steering gear had a grease zerk on it. It eventually came to me that this was an old farmers trick... i.e. When the seals give out in the steering gear and all of the oil leaks out, punch a hole in the fill plug, put a zerk in it and pump the whole gearbox full of grease. It apparently worked on my tractor, because when I put it back together I poured some 90 wt. into it, and now it's leaking like a wet sow, lol... Pretty soon I'm going to pump it full of thick grease again and forget about it. I'm sure that as little as these old tractors get used it won't hurt a bit, and besides, it's only another ONE of the hundreds of grease points to remember whenever one gets serious about lubricating these machines that we love so much.

DC, I'd be interested in looking into some parts for the worm gear. I'm sure that just getting some fluid in her will help some too!

Joe, do you have a parts breakdown of what's in the steering box? Still trying to figure out what the tension bolt of the bottom right of the housing is supposed to do?

Yup. There are 6 pages in the service manual. Some of the info you probably don't need or want, but adjustment info is mixed in.

Do you want the parts manual pages also?

Joe, when you get a chance, that would be great. Whatever you think I need, couple service manual pages and a parts page? I'm just curious what that adjustment bolt on the bottom is pushing on and if the new "fingers" would solve my slop? I just put fluid in it and that made it a little smoother, still about 30 deg slop though. My tie rods are shot too though so I don't want to get too carried away on fixing this slop, would have to rebuild the entire front!

I have concluded that the previous owner absolutely loved to stick weld, I think he did it just for the heck of it in some spots, figured that it "kinda needs some extra support here and there"!

Hi Ed, having a problem with my scanner, probably just needs the software reinstalled?

I made copies from the parts & service manuals and snail mailed. Some of the pages are for other than a utility tractor but you just about have to read it all to get the whole picture.

I would lift the front with the bucket and move the steering back and forth at a tire to get an idea of the linkage slop. Adjusting the cam & lever is in the material that I mailed.

I will be taking mine apart, while moving the bolster around the cam rotated off the adjusting plug and is now hung. I am going to wait until engine is done and the bolster is mounted back on the tractor.

I am thinking of mixing 90 wt with STP for lubricant, haven't found any 140 wt yet.

Joe

Thanks, time is not crucial so snail mail works are great. Most of what I will be doing involves the backhoe so steering is not crucial, just one of those safety things that I like to check in on everyt now and then!

Good idea lifting the front end off real quick with the bucket. Will try to get a pick of one of my tie rods posted, prev owner tried to fix something and I am not sure what I am dealing with on one of the knuckles.
