    When converting to gear pump, the priority valve spool is replaced with a unloading spool. This , along with an orfice properly plumbed into system, allows the gear pump to dump it's flow to tank through the unloading valve until a aux valve is called upon . You have got to be running against high pressure with your set up and it will not work out.
  2. Different style of linkages from 656 to older like SMTA up through the 560. Same end result though as you need free travel on both clutch and TA throwout bearings and complete release of both clutches when depressing the main clutch pedal. Again, depressing main clutch should release TA clutch same amount as pulling the TA lever to release TA clutch.
  3. I knew Floyd Jensen but not real well. He did call on us a few times and was involved with service training sessions a few times. Dave Christofferson was our service rep after the merger. He was from the Case side, RIGHT. Julian Yerbich was rep for a few years. Earl Cramer worked out of St. Paul as head of service for the area. New him quite well. Ben Daniels, Hector Sharbino. Lots of guys. Lot of water under the bridge since then. Had a little go around with one of them, can't remember his name. He got put in his place right in front of a group at a training session when he misled them about a warranty claim that IH denied after he said we would not be left holding the bag. . Said he talked to the mechanic at our dealership and I corrected him and told him, I was the mechanic, only one.
  4. I don't recall the degrees of timing advance on the 301 in tractor or combine. BUT, the whole deal is that what ever the shaft is marked like previous poster said, is the degree the timing should be adjusted to AT FULL Throttle. Working correctly, (which most old worn distributors don't) the timing would fire at or very close to top dead center with a low idle speed of about 500 rpm and gradually advance with engine speed until full advance was reached just before rated engine speed. So, i'm betting it is 17 or 19 degree total advance on that engine.
  5. Cory had a saying, BC, before Cory. That was when we referred to something before his time with IH. We had a young fellow for a little while back farther than that. Was when first robot heads were introduced on the IH combines. Jim Minnehan was his name and he went on to teach hydrostatic drive at Hickory Hills in the late 60's. Had him for instructor there in 69. From there he went on to combine development work I believe. He was just out of Vo Tech when he started with iH and went places. We had another one that came out of Watertown I believe. His name was Bill I think and he was well versed in IH . He spent a time down south and his stories aboiut the cotton pickers were very interesting. Had several good guys but a couple of you know what also. Desk jockeys I called them.
  6. The off set points were used on the 6 cyl gasoline engine from 706 on up with IH distributor of course.
  7. Corwyn Lepp (Cory) started with IH around 1980 I believe. Had him for service rep in Madison, Mn for a while. Last time I bumped into him was in Titan store in Watertown, SD. about three years ago . What I remember about him was he liked electrical work better than hydraulics. Didn't get all oily. I had a problem with a intermittent oil pressure loss on a I believe 1460 combine. I had checked several things and he got on the phone with a service mgr down the line somewhere as he thought he had run into that problem once upon a time. He suggested that the oil baffle in the oil pan was loose and would get sucked up against the screen of suction tube. I was able to drop the oil pan an inch or so and sure enough, reached in an pulled the baffle out. I had overhauled that engine recently so the oil pan gasket was in good shape so lucked out there. Biggest problem was owner had to shut the engine down hot too many times when he lost oil pressure and it took the turbo charger out so still very unhappy customer.
  8. Does it shift out of gear ok with TA lever back ? If it does , your adjustment is not correct. When you depress the clutch fully with TA lever ahead, the TA have to be released the same amount as if you pull TA lever to rear. Make sure you have close to 3/16 free play on TA lever in that long slot with TA lever ahead, spring attached and clutch fully engaged and then adjust that short link just so pin can be inserted.
  9. That is the correct part number. It should fit snug on a smooth surfaced tube. You install it in the rear frame with lip on seal toward center of tractor . When you drive it in place you have to use something that fits the outside diameter of that seal very close or you will crush the retainer and then the seal will be loose fit on the tube. No rounded edges on installing too. I think some books said a socket would fit but I would never use a socket as they all have chamfered rounded edges. It is very touchy to get it in there right. Lot of them are not. You test it after seal is installed to see if it fits snug, and then you install the tube after the pump is lightly bolted in place.
  10. Probably pipe is too short as clamp should be above hood.
  11. Feel the new one for side and end play. May surprise you.
  12. It also has the H manifold which has a smaller flange for carburetor mounting. New, aftermarket manifolds have a universal manifold so they will accept either the H carburetor or Super H and 300 carburetor by having slotted mounting holes. I have one on one of my H Farmalls.
  13. Sad he didn't get to enjoy retirement longer and what a terrific line up of the RED TRACTORS. Forever RED had to be his calling.
  14. By repair I mean replacing the O-rings, and actuator parts. That is the parts that are serviceable and I am sure that is what any after market supplier is doing as well. It would be way too expensive to repair the bore and then you would have to make a new spool. I repaired those valves since IH started using them in the 706 etc at the IH dealer. They used same basic valve up into 66 series and then continued with very similar valves through 50 series. Even the 300, 400 , 560 used a spool valve, just a different style. We sold a lot of the check valves over the years to eliminate cylinder drift. All fast hitches used a check valve, some a single and some double check depending on model and year of tractor.
  15. A check valve bolted to the side of the block couplers come out will hold a load up forever. Quick easy check to make sure cylinders are not the problem is to raise implement and grab hold of the two hoses coming out of coupler. Raise hose should be under pressure and other hose should be free in coupler. Don't unhook both hoses to test as then the rod on cylinder will occupy space in cylinder when cylinder leaks, thus no place for oil to flow so even a cylinder without a seal will hold up a load when both hoses are unhooked. I don't really know how anyone could rebuild one of those aux valves to reduce leak down as they are a spool valve fit into a bore and only replaceable parts have nothing to do with leak down. Repaired hundreds of them over 40 years at least.
