Engine On 1952 Allis Chalmers G Tractor Replaced With Kohler 25HP Engine
 ✖  |
Harold Stoudt, Hamburg, Pa.: "Several years ago I completely restored my 1952 Allis Chalmers G tractor and rebuilt the engine. Recently the engine crankshaft broke. The original Continental engine is no longer made and parts for it are no longer available. I use this tractor a lot to clean my barn and for other jobs, having built a front-end loader for it years ago. I didn't want to give it up so I removed the engine and replaced it with a new Kohler 2-cyl., 25 hp, air-cooled gas engine. It works great.
"To mount the new engine I mounted a 1/2-in. steel plate against the original clutch housing and attached the new engine mounts to it. I had a machine shop make a 1 1/4-in. dia. shaft which has a hub on the end of it that matches up with the tractor's original flywheel and clutch. The engine uses three V-belts to drive this shaft. The original engine ran at 2,300 rpm's, but the new engine runs at 3,600 rpms so I had to carefully calculate the belt ratio to maintain the original drivetrain speed.
"The Kubota engine has a big muffler that's right behind the tractor seat. To keep its heat away from the driver, I mounted a steel shield between it and the seat. The shield mounts right where the original radiator used to be (the air-cooled Kubota engine doesn't need a radiator).
"I paid $1,576 for the engine which I bought new. The original 4-cycle engine was rated at 19 hp but the 4-cycle Kubota engine is rated at 23 hp. However, the horsepower on the two engines is about the same because newer engines don't have as much torque.
"The original engine weighed 225 lbs. but the Kubota weighed somewhat less than that. I wanted to keep an equal weight with the new engine so when I used two pieces of 8-in. channel iron. The engine mounts on a steel plate that's bolted to an 8-in. channel iron frame. The bolts are welded to the top of the frame and can be adjusted so that the engine can be raised or lowered in order to tighten the V belts. I also mounted a drawbar on the back of the frame.
"I also mounted a belt-driven hydraulic pump behind the shield. The pump is used to operate the loader.
"No plans are available."
