Can anyone help me figure out what is wrong to cause the rear steering control valve to bend the external threaded part of the spool?

redfarmer. I don't know if you'll see this post or not, but I own a 4166 and when I got it ,it already had a home made brace assembled around that steering cylinder and rod. I can't say why it was bending , but apparently it was a weak spot. That whole rear steering rig is a goofy affair. I'm fairly familiar with it because I've been working on it every little while. It's nice when it works well as the tractor really comes around. If I can help you more, post back or e-mail me

Thanks for your input.I have gotten several ideas off the internet of what to check and one of them led to the discovery that the hydraulic pump was shot.It is going to take a few weeks to get the new pump so I wont know for awhile if its fixed.I am also wondering from the discussions if it would help to supply the steering valve right from the pump rather than the line that goes all the way up front to the brake valve and then back again.Any thoughts?

Hmmm, I'll look in my shop manual and ponder that and get back to you in a day or two. Are you thinking it would supply more pressure or be more responsive? My 4166 seems to work fine hooked up the factory way. I have owned it several years and used it regularly. Here's one clue though. Previous owners put a note on the dash that says " only shift to 4 wheel steering when tractor is moving". The reasoning, I believe, is that if you have the front wheels turned and shift to 4 wheel steer, the rear wheels will immediately try to turn the corresponding amount . When standing still, that would put a lot of pressure on that cylinder and rod behind the frame. I have 1500 lbs of calcium chloride in all four tires and I suspect that may contribute to the bending of that cylinder rod.
I'm also curious about your hydraulic situation. Mine lifts implements slowly and they settle too quickly. I think that's a different hyd pump from the steering hyds, right? Do you think that may be a pump problem too, or bad seals in the spool? I'll do some research and check back.

My thought with the plumbing change was that it might make the circuit more prioritised to the steering valve than the brakes sinced two other guys had responded and were pretty certain the problem had came from lack of hydraulic pressure.As I look back signs of the pressure problem started last summer when I was barely able to fold the wings up on a 28' field cultivator.Then I used a backhoe on it and things just got steadily worse.I don't know if you have a three point but I do so my pump is the 30 gallon pump which operates the rear steering and brakes on a built in priority circuit,the remaining flow is given to the hitch and auxiliary circuits.The front steering is supplied by the 9 gallon pump which also supplies the transmission lube circuit and oil cooler.You mentioned your implements settle too quickly,if you mean they just gradually go down I would suspect worn spools.Since hydraulic valves use only a tight spool to bore clearance to seal the oil there isn't anything you can do to the valve once it is worn. You could however add a check valve to the circuit after the valve,this would hold the implement in any position until pressure was applied in either direction.Hope this helps.

Well, I got out my shop manual and looked through it. It seems like you're on the right track. I'm guessing that the new pump will take care of your problems without changing the plumbing. That still doesn't seem like it would have anything to do with the steering rod bending. I suspect that my 4166 needs a pump as well since it has similar symptoms.
Do you have a service manual for the tractor? I have the Blue Ribbon manual, so if you need any info from it, let me know. I'll be happy to help if I can.

Thanks for your input and yes I do have a service manual from IH.As for why the steering rod bent maybe this might help explain it.One guy responded on the internet that after the lack of pressure the next thing he would suspect was the rear steering cylinder.The other day I talked with a dealer mechanic who remembered working on one and he said the same thing but explained it like this.If the seals in the cylinder are leaking and you are in four wheel steer,when the front wheels are turning the rear cylinder doesn't respond because of the leakage and so an extreme amount of pressure is put on the rod thus bending it at the weakest point.After learning this I have decided to also reseal both steering cylinders while I have in the shop.Thanks for your responses and hope this info might be of help to you.
