  1. You may have lost spines in pressure plate hub. Then no hydraulics and no DD pressure in TA. If sprague is weak it may not always "catch". Will free wheel in low TA since no pressure for hold back clutch. You can look at clutch ares through bottom cover.
  2. Block was a check valve IIRC.
  3. Intake system all good? Can you take off at carb and run in clean environment?
  4. I think some of the super high auction prices are a wink and nod kind of deal. I buy your H for $40K and you buy my rare Super W-4 for $39 K. Purebred cattle used to be that way.
  5. Probably not your problem but when rod linkage from shift arm on outside of transmission case to the drums on dash are correct the lever should not be tight against end of any slot in any gear.
  6. On start up does one exhaust port warm slower? Red neck method is hold thumb or fingers on manifold. Or pull injectors and test. Preferred. Red neck method works well with dead injector, less so with dribbler.
  7. How many hours on pump? Ambac pumps usually don't have the courtesy to quit all at once.
  8. Wheel track planting. Big new thing when I was 10 back in 1959. Does that wide front have wheels and rims like a 400? Looked again and hubs are not right for any IH front wheels I am familiar with.
  9. You may get it right for max power but advance curve may be way off.
  10. I had same symptoms on 7140. Turned out to be s-l-i-g-h-t-l-y loose where positive cables hooked on stud at starter. Cranked fine.
  11. Believe pto disconnect discontinued at some point in production.
  12. When you move inner level with nothing hooked to the hoses the system will build to relief valve pressure unless the oil finds somewhere else to go. I am guessing that the Tela-Depth valve due to busted gears and sticky linkage is letting fluid by and into fast hitch cylinder. I have a Deere 9500 combine. If the unload auger swing valve is engaged and you try to lower the reel it will go up instead. Oil under pressure looking for someplace to go.
  13. Yes you can replace with regular valve. Will be equivalent of 400 or 450 hitch control. Be aware the valves can be set for single or double action. Others will know more.
  14. I have a 7140 Magnum. The outlets used the most got so you needed a flat pry bar to help pop them out. Rebuilt and much better. Think taking apart and cleaning would have done the same but hate to put used parts that aren't that expensive back in coupler. If you give it a good firm push in FIRST they uncouple a lot easier. I always prefered lever style couplers and slightly prefered IH to Deere. Not as fussy about having the barrel pushed back towards you.
