Allis Chalmers HD20 back into service. Detroit Diesel 6-110

This is a compilation of short videos taken of an Alllis Chalmers HD20 bulldozer. This dozer sat for 15 years until I purchased it last year. Now finally I have put it back together and taken it out to work the engine for evaluation. This crawler has the GM 6-110 2 cycle engine and is a 1952. Hd20's were only produced in torque converter drive. So far it has slobbered a lot of oil just unloading it and moving it around. Hopefully getting the engine up to temperature will loosen things up she will run clean. The air cleaners were partially crushed and in sad shape. I did what i could to straighten them out and added a reinforcing ring in the center. The new muffler I fabricated is a copy of a nelson that came with the tractor but was too far gone to use. I plan to use this dozer in the future and it will be featured in more videos. There is very little footage of HD20's on youtube. Hope you enjoy.
