I have a 1979 Case 2470 in the higher serial number range. When I turn the front wheels and have the rear ones in "auto" the front ones turn and then the rear ones pulse slightly and then I can hear a bypassing-like sound from inside the cab. I thought that my steering cables may have been seized but they aren"t, and I thought that one of the steering cylinders in the rear might have bad seals in it but they are good. I was wondering if anyone knew what I could look at next or if there are any diagrams out there that would help me. Thank-you for reading... Joe

The service manual that I have is very user friendly and thorough. It is a very good service manual. The trouble shooting procedure looks to be fairly lengthy. It basically involves starting at the pump and checking the hydraulic pressures at each of the devices in the steering circuit.

You really should have a manual.

They are pricey, they go for $120 up on ebay. I paid $180 for mine at the dealer.

Joe,
Is your 2470 new to your operation?
We have both a 2470 & a 2870 on our farm and I'd say the noise your hearing is normal, at least our 4x4s do the same, at least at slow RPM. I've not noticed it at field speed/RPM. Therefore we keep the rear steer lever in manual mode unless we're in the field. As is recommended in the operators manual. The manual also says never to use automatic mode or move the rear steer lever at road speed.

Explanation: per the Service Manual the oil pressure to the rear steering system is lower below 1500 RPM than at PTO RPM. This is intended to prevent "jerky" rear steer action. Either in Manual or Automatic mode. We have learned that during barnyard (slow RPM) maneuvering the rear steer is basically dead. In order to use rear steer to hitch-up to an implement the operator needs to push-in the inching pedal (clutch) and rev the engine a little while moving the rear steer lever manually.

We have Operators, Parts and Service Manuals for both our 4x4s. There are a few pages for the rear steering system explaining: "How to Works" and Troubleshooting. If these could help you please Email and perhaps I can help further.

Any help right now would be greatly appreciated. I The flow divider valve, the flow meter valve or the rear steering control valve could be giving me the trouble. Do your books tell me how to troubleshoot these parts? If they are user friendly enough I may have to pick up a copy of them for myself.

This tractor has been in our family since 1988. Dad bought it with 5000 hours on it and since then we have done the engine, and a few small repairs and I put on a home-built air breather system and cleaned up the paint a bit. We use it to put in 400 acres of crop each year, but it has never done this before.

I looked in my 2870 service manual and there are all kinds of diagnostics procedures, way too many to cover here. But it could be the flow divider valve, the flow meter valve or the rear steering control valve.

As far as diagrams go the whole parts manual is available on line at www.caseih.com.

Go there, click "Search for Parts", then click where it says "Right Here" in small print, then key in your model number and look at the parts you want to.

There are a few guys that come to this forum that have good knowledge of these tractors. Hopefully one of them will wee your post and be able to help better.

Good Day,

JP.

Joe, I agree with Mr. jogl. Get a set of manuals.
The Case Service Manuals are better than any I've seen. Including the Auto companies. The best and most unique feature is the "How it Works" section. Each separate system of the tractor is clearly described with color schematics and shop-level dialog as to function. Really helpful to understand how something works when your trying to fix it.

Be aware that there are separate manuals for the different tractor models. For example, the 2870 book will not be right for a 2470 Engine or Tranny. The designs are quite similar but the mechanicals and hydraulics are certainly not at all interchangeable. The troubleshooting area will get you through the steering diagnosis.

Just make sure you get a Case OEM manual not a third party aftermarket... waste of paper. Suggest a Parts Manual too. I find the exploded views to to be quite helpful. Also, when I walk into my dealer with a part number list he always buys the coffee. And, if I'm willing to wait for the parts about a week he will order them as part of a "Stock Order", which saves me 10-15%.

I also got my manuals through eBay. Just make sure the one you find is not too shop-worn... dirty with torn and/or missing pages.

Well thank-you guys for all of the help. It is sure nice to have something like this to be able to talk to others who might share something in common.

I looked on the caseih website today at the parts diagrams. They are in an exploded view that are very good to print out. Ebay Canada doesn't have any manuals right now, but I am going to keep my eyes open. Thanks again!!!

Joe

Joe,
Here's the manual you want. Now on (US) eBay for $90 + $8 shipping. Only a couple of days left. Doesn't say he won't ship to Canada.

Link

If a copy & paste of the above link doesn't work. just go to ebay.com and search for item 220217160180.
Good Luck.
