Tractor Rebuild New Parts and Engine Repair
I went back and forth a bit on whether to rebuild or scrap the tractor. I would only consider rebuilding if I could find a brand new wiring harness and the engine was okay. I didn't want a used harness or to try to build something and chase gremlins forever. Fortunately, I found a factory new harness, one of four left for this 21 year old tractor.
To see if the engine ran, I was able to disconnect the secondary injection pump supply and temprorarily wire up enough parts to start it. It's a mechanical injection engine, so power for the fuel shutoff solenoid and the starter itself was required. It ran properly, so I forged ahead.
Most people would be scared of this much wiring, but I was a mechanic and I am an engineer, so it was no issue. It was actually a very simple system. I didn't even need to look up the schematics.
The first of many boxes of parts had some of the basics. I was able to get a used valve cover as well. I changed the oil first because the fire departement did put some water on it to cool it off and the melted valve cover likely let some into the crankcase.
Here you can also see the new fuel head, filter, and fuel lines. This is the low-pressure side. The secondary injection pump is on the other side of the engine.
