B210 steering

Recommended Posts

Is there something that is supposed to go in the pocket on the bottom of the tractor that the steering column terminates in? When I got the tractor, there was nothing on the end of the shaft so I added a couple of washers and a nut. The steering has always been loose at the bottom. When making a turn, I have to be careful or the gears will separate allowing the wheels to jump to the side. I had thought this was caused by the end of the shaft being worn out or the collar that the column runs through being worn. I just pulled the column and checked the parts. The collar appears okay, a new bolt drops right through and doesn't wobble around. The threaded end of the yoke appears somewhat worn, but I wound't think enough to cause this problem. It does appear that the gear on the bottom of this yoke is slightly off center. Is there such a thing as "gear timing" for this, or am I missing something. SHF

Boy, can't ask for more than that! I guess I'm going to have to clean that area out a little bit better, there's a lot more parts in there than I thought. I notice there is an instruction to grease the needle bearings. If I remove the attaching hardware and steering arm assembly, are the bearings going to fall out on me? I only ask because I've had that happen a few times with needle bearings and it's a pain picking up all the little needles when they spill all over. Thanks for the diagram, sure helps. Steve

If there is plenty of grease in the bearing the needles should not fall out if you are carefull. Do it in a clean area. But murphys law always applies. This & $1.00 might get you a small Coffee Maynard aka/UCD

Once again, thanks for that diagram. I think I found part of the problem. I didn't realize the gear is supposed to rotate on the eccentric pin. Mine was frozen and I thought it was supposed to turn as one piece. I've loosened it up and I'll try dropping the whole shebang back in to see what happens. As to grease in the bearings... I think I'll put a plastic tub under the tractor when I pull those bearings. Is Murphy's law the one that says: After I've fought with something for an hour and a half the wife will come out and with a flick of the wrist make me look like a total idiot? SHF

All done. No problem with the bearings, they appear to be pretty well supported. The yoke had frozen to the eccentric pin, which was causing the problem. It was like that when I got the tractor, and I had just assumed it was all one piece. I loosened the parts, cleaned them and lubed with Anti-sieze. I don't know if it will work as well as grease, but I noticed the adjusters on the rear brakes of my car came lubed with it from the factory. Is this a common problem (yoke freezing to eccentric), if so, has anybody tried drilling and tapping a hole in the yoke to accept a grease zerk? It would make the whole job a lot easier. Also, there are a pair of mounting points attached to the lift rod and located right next to the drive shaft. Is this the location for adding a hydraulic cylinder? If so, where is the other mounting point? If this works, here's a picture. Steve

To install swivel fittings (Ref. No. 20), first lubricate O-ring with light oil. Then turn swivel nut until O-ring is seated. Turn fitting by hand to align with tube nut. 2. To install tubes. first align threaded fitting with tube nut. Then thread nut onto fitting and tighten. Hold fitting and turn nut with wrench to seal joint This & $1.00 might get you a small Coffee Maynard aka/UCD

It occurs to me that a couple of the guys have talked about blowing out the flex disks. Doesn't that do some major damage to the hydraulics if they're encased right next to the shaft? I noticed there is an electric lift unit from a JD over on ebay. Steve

Steve I have blown out two drive shafts on my 7790 and it hasn't done any other damage other than bending the shafts. This & $1.00 might get you a small Coffee Maynard aka/UCD
