Fred a 600 combine used the same pump I think
The 600 combine used a similar John S Barnes pump(now Eaton) but it had two stages, one for steering and one to lift the pick up head. I was sold one of these (junk) once that someone had tied the outputs together and sheared the woodrufff keys on both pump gears. Be very careful when trying to use a combine pump, it will mount but it is a different John S. Barnes pump. Some parts are still available for this pump but not the special Case contract parts.
I have the parts break down on this pump both the earlier model and later model. Let me know if you need these as a PDF file.

your are correct I forgot to add you would need a 600 with manual steering
I am not sue if the pump for a manual steering 600 combine would be big enough. From my research it looks like that pump would have insufficient volume and maybe pressure to power the 630 steering, I am guessing it is the Char Lynn type steering like I have on mine.
I am just about ready to start her up since I did the manual to power conversion, body work and painting on the tin. The cork gasket on the fuel strainer is leaking like a sieve. I am hoping after it sits a few days exposed to gasoline it will moisten up a bit and hold.
The tractor pumps are hard to come by but they are out there. I have some pump pieces that may be of assistance to Fred if he has any interest.

the hdr pump was at least 7 gpm and that would be more than enough for steering, I will look up the hyd specs to be sure,

Fred: Depending on how original you want it, our 630 has the oil filter laying horozontal & a pump & tank off a backhoe bolted in. Makes the steering effortless, with a loader on it besides.
Just going by the pump I had whose model number equated to the combine pump, then I looked up the sizes for the pump gears on the Eaton site, they still make a similar pump with the same gears. Just from what I was seeing it looked like the longer gear was for the steering and the shorter gear, on the two stage, was for the pick up head. Without a bunch of digging I don't remember what the out put was but I bet you have some technical data I don't have. I agree, if its 7 gpm or greater it will work. I want to say the tractor pump was little over 9 gpm.
The two stage pump that was supposed to be the right thing had one pretty long gear and one little short gear. I figured the short one was for the pick up head.I still have the old parts if we need to do some comparisons. The shafts and gears are bad but the housing blocks are in pretty good shape. The shafts are no longer available from Eaton but the gears are. I had considered having new shafts made at a machine shop but found a pump for $50 and didn't thinks I could get shafts made for that.

this is the belt driven pump which is bigger in size than the the gear driven one on the 600 the 660 has hydrostatic steering like the 630 so I scanned this, I can tell you a 2670 does not have 9gpm to the steering and to have that much flow you would need a much larger amount of oil to keep it cool also if you like I can scan the 600 book also
Sent Fred my parts break downs I got from Eaton. The 1985 version on the drawing said displacemnt was 6.5 gpm at full throttle, 1.0 at idle. Don't know where I got 9.0 from but I looked at a BUNCH of stuff trying to figure out how to rebuild what I had before I found the replacement.
