Bulldozer powered by Oldsmobile engine
An old D.D.H. Oliver O.C.15 dozer that had a blown engine but a good set of tracks turned into a powerful performing machine for Delbert Frey, Stanardsville, Va., after he fitted it with a replacement Oldsmobile gas engine.
"I originally bought it for the tracks. I wanted to put them on another Oliver dozer. But after looking it over, I decided to rebuild the 6-cyl. Hercules diesel engine. However, when I discovered that the crankshaft was ruined, I gave it up and the dozer sat around for 2 years before I got the idea of putting a 1970 Olds 454 engine and automatic turbo transmission in it.
"After some measuring, I lengthened the frame of the dozer 18 in. and installed motor mounts. There was a flexible yoke coming out of the dozer transmission with a splined shaft which was exactly the right size to match up with the spline of the driveshaft on the Olds transmission. I connected the lever which originally operated the clutch to the automatic transmission control. The hydraulic system was originally driven by a driveshaft off the crankshaft pulley. I turned a hub which fit into the crankshaft pulley on the Olds engine to do the same thing.
"I had to incorporate an air compressor since the dozer had air steering controls. I had an old White road tractor with a compressor so I mounted it so it would be driven by the same belt that drives the water pump and alternator. The hood was lengthened to cover the lengthened frame. The exhaust was routed up through the hood. "I've used this dozer to clean off about 75 acres of heavily wooded land, to build a new road into the farm, and to build a 11/2 acre pond."
