Hello. I just acquired an older D7. Well at least my grandpa said I could have it if I could get it running. So as you would expect, the journey has begun. From my research, it may be a 1946 year model? I know it may not be worth much, but it has been in my family for many years. It is a farm tractor without any blade or cable unit. My grandpa and uncle added a properly sized turbo and had the injection pump turned up appropriately. Someone also built a cab and installed an air conditioner. In the process, the throttle got moved to the side and several gauges were added like EGT, boost, and others. Ok, I will try to answer your questions. Have a good day!

That's a nice straight looking tractor. How long since it's been going?

Very cool, Cameron. You're in the right place to get help. A bunch of tips that you'll hear from folks:

  • drain a sample from every fluid compartment - engine oil, transmission, final drives, pony crankcase, both fuel tanks, coolant, etc, to determine if they're contaminated. You'll change all the fluids anyway but this will tell you what kind of condition those compartments are in

  • change all those fluids : )

  • get a new magneto file and dress the points, check for spark, and if none, replace the plug wires (solid core only) and condensor and check again. Clean or replace the plugs

  • check that both governors and the fuel rack move easily

  • create a first startup video

Nice looking machine - Take the Air Cleaner apart before you try starting, that goes for the starting engine air cleaner too. Yours would not be the first to have "critters" making use of them for houses. Was the exhaust pipe covered? Hope so. Use care taking the cap off of the magneto - you do not want to break the brush or lose spring, etc. If you remove it, make certain you mark the position so you have it correct upon re-installation. Check fuel tank, sediment bowl before you put gas in for the starting engine. Clean as necessary, this will help prevent sending "gunk" to the starting engine carburetor. Congratulations, your adventure begins! cts

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
