Starting a TD25 dozer after sitting for 20 years.

 Used to work for International and we kept this exact model dozer running without the blade. We used it for heavy pull jobs around the factory. We also used it for a counterweight for snatch blocks and pulling out scrapers from the coolant pits during shutdowns. We started it once a month on a set PM schedule and let it run for a hour to get up to temp and I would hit the dozen or so grease Zerks. 50 years old and still a useful piece of equipment.
 WE had to pull a TD 25 out of a pond it was digging. Our friends got it stuck and buried it trying to get un-stuck. It weighs about the same as a D-9, I think. We took a D-8, a 325 excavator, a trailer load of cribbage, and a D-6R. Before it was over, a couple of farmers brought large 4 X 4 John Deeres over to help. Stout tractor!
 Looked like the turbo had been replaced looked a lot cleaner than the rest of the motor ! An I to find it hard to believe that it started that easy an moved that easy ! Usually the tracks are froze in place after setting that long !
 Diesels need compression to startup. Better batteries equals faster cranking which in turn equals higher compression which is what fires the fuel. Got to have good batteries!
 What a great looking machine...Big wide tracks  stable looking platform cant see why people leave them to rust.....Should crowd fund respray and refurbishing it with a roll over roof..
 I just don't understand why people spray starting fluid before the motor is cranking and slug the motor up. I was always taught to squirt use starting fluid while motor is cranking. Got to build heat with compression and then combustion will occur. I really think that dozer would have started on diesel alone if it had cranked faster. Just my opinion. Awesome to see it run and the steering clutches work.
