Chevy Engine Beefs Up Allis Chalmers WD

Chevy Engine Beefs Up Allis Chalmers WD ENGINES Engines 29-1-19 "My 1955 Allis Chalmers WD 45 tractor didn't have enough speed or power and also didn't have enough hydraulic capacity. So I repowered it with a 283 cu. in. gas engine out of a 1959 Chevy, and I added a hydraulic pump on one side of the tractor. The results have been beyond my greatest hopes," says Clark Carpenter, Hamilton, Montana. The tractor was originally equipped with a 4-cyl., 226 cu. in. engine. The new engine was larger so he had to cut away part of the frame rails on both sides to make room for it. He used 3/4-in. and 3/8-in. thick steel plate to make a pair of adapters that connect the engine to the transmission. Then he rebuilt the frame rails by welding in the frame rails from an Allis Chalmers WC tractor. He also added a new pair of exhaust mufflers. There was a big 12-in. dia. belt pulley on one side of the tractor, which he removed. Then he made an adapter so he could attach the hydraulic pump to the end of the pulley shaft. The pump bolts onto a steel plate, which bolts onto a homemade metal sleeve that protects the shaft between the pump and the tractor's frame. Hydraulic hoses lead from the pump to a double hydraulic valve that he mounted on the fender. An intake pipe goes crosswise down under the tractor to a hydraulic reservoir that he mounted on the other side of the tractor. The reservoir wouldn't feed the pump properly with oil because the oil level was lower than the pump, so he added a 1 1/2-gal. tank above it. He also added a pair of remote outlets on back of the tractor. "The tractor was already quite agile and could turn on a dime. Now it's also powerful and speedy," says Carpenter.
