Have purchased a Warner-Swasey Gradeall with a GM3-53 diesel engine and a Fuller 5B33 tranny. I know the engine was running 2 years ago, but it has been sitting since then. I am interested in either rebuilding it or selling it as is. Just need some input from someone who can tell me if it would be worth rebuilding. Any info on this motor and tranny would be GREATLY appreciated. Never worked on a diesel before. It also has a Chrysler HT-318 motor in it. The guy didn't say whether it was running before or not. I am selling parts of the Gradeall, but thinking about rebuilding the engines.
