155-John Deere 50D Mini Excavator repair project (part 2)

In this part 2 of this Mini Excavator repair series, I begin the tear-down and interior work. This includes chasing down some electric issues, and repainting some of the interior panels. I also put off several of the exterior panels and begin pounding out dents.

I would definitely prioritize fixing the overheating issue over everything else. If this machine was ran in a really dusty environment (they normally all are) then the evaporator normally plugs up with dirt externally with result in no airflow out of the vents. Same with the radiator and coolers, but these are much easier to blow out with an a blow gun. I’ve seen several John Deere water pumps lose the impeller (plastic) and then just spin freely.

Thanks so much for the advice. I'm learning all the time, so your experience is much appreciated.
I'm a little behind in my video editing, but I believe I've fixed the issue. However, I did replace the air filter and made sure the radiator, etc. thermal exchange devices were clear of dust and debre build-up. I did not replace the pump since it is such a massive effort, requiring removal of counter weight and a ton of other parts. I figured I'd see how it runs after doing a full flush, replacing the T-stat, and the V-belt, of which I think was the true culprit. It sounds a 1,000 times better, and is staying cool. It was so loose and warn out. Should have replaced it long ago.
Everything appears to be working perfectly now. Stay tuned to see the outcome. And keep your experienced advice coming on my future projects. I'll look forward to it.
Have a fantastic day. T.
