  1. I didn't know there were any NH combines painted yellow before the twin rotors were produced. All I've ever seen were red ones.
  2. My guess would be a leak between the tank and pump. It may not leak fuel out but air may be drawn in by the charge pump forming tiny bubbles. As long as the engine stays running the pump can handle the aerated fuel. When the engine is shut off all the little bubbles join together to make too large an air pocket for the pump to handle without bleeding an injection line.
  3. Hopefully there is something wrong with the numbers you posted You show up to .050" differences between cylinders and up to .100" between piston and bore.
  4. The MTA engines runs slower than the newer tractors so that should help slow down the speed.
  5. Normally you can leave the original schrader valve in place. The adaptor will have a pin in it to open the R12 valve when installed.
  6. You can ignore this reply. My dyslexia bit me again and I was thinking 1206 not 1026.☹️ Your front pump has gotten air locked and is worn enough so that it is not able to pump the air out under pressure. There is a simple way to allow the air to escape without being under pressure. On the side of the MCV that faces the rear axle there is a plug that takes a 5/8" wrench to remove. Remove that plug and start the tractor. Be ready to stop the engine when oil shoots out. If you still don't get oil out with the engine running you can blow air in the oil filler tube using a rag to seal the air from escaping.
  7. As mentioned above when the flywheel ring gear and the starter drive get worn they will lock the engine instead of properly engaging. If not too bad rocking the tractor in 5th gear will usually free them up. The solution is to file a bevel on the left side of the ring gear tooth, leave the right side (the driven side) flat. I have sometimes bevel the starter drive gear at times but it is best to replace it if it has too much damage. If the vertical (Delco-Remy) distributor still has the 6 volt coil running on 12 volts without a resistor the points will burn out in a short time causing the timing to change. A 6 volt coil will have about 1 to 1 1/2 ohms resistance. If you have a 12 volt coil it should be about 2 to 4 ohms. If you are playing musical chairs with the starters, the one on a regular M should be the same as the H.
  8. Two options come to mind. 1) Use a key switch for a lawnmower with magneto ignition. 2) A little more complicated, especially if the system is still 6 volt. Use a normally closed relay for the magneto kill wire and ground the other load wire. You would also need a key switch which would then provide power to open the relay when running.
  9. I always used two sharp picks and pried from both sides. Usually took longer to grind the head down on the new key than to remove the broken one.
  10. The exhaust manifolds on the DV550 were the same for both sides. There was an exhaust elbow on one end and a block off plate on the other. Just a simple matter of using four elbows instead of two.
  11. Probably too far away from you but I have a pair of TD9s that I was going to make one runner out of them. One is a 51 model and the other a 56. The newer one was in a garage that burned down around it about 40 years ago. I had the engine running and drove it a bit when I first got it but it has been sitting in a pole barn for about 25 years now. The engine is a later model than yours, a 350 CID with the full flow oil filter system rather the the bypass filters that were used on the 335 CID engines.
  12. My Dad and I saw that tractor in Rochester, MN, Olmsted County History Days, in the early or mid 80s. It was displayed in a box with glass sides. The owner said he was trying to get JD to acknowledge they were connected to the machine but all he was getting from Waterloo was dinials.
  13. The starters are all the same number from the 806 through 66 series gear drive tractors until sometime in the final year of the 66 series when the changed to the starter that the 86 series used.
  14. There are four bolts inside the lever housing that hold the drive end frame in place. That end frame can be assembled in I think twelve different positions to clock the starter however it is needed to fit the application.
  15. Looks like an old style grease gun in her right hand. My dad had one like that and another one about half as long.
