Transmission And Hydraulic System Modified On 1946 Allis-Chalmers WC Tractor

Transmission And Hydraulic System Modified On 1946 Allis-Chalmers WC Tractor TRACTORS Modifications 21-4-36 The 1946 Allis-Chalmers WC I bought in 1972 was equipped with a transmission that was geared too high for slower jobs and a hydraulic system that limited me to using only a blade. I modified both the transmission and hydraulic system so I can now use the tractor to bale hay at a crawl as well as run my home-made hydraulic wood splitter. I installed a 4-speed New Process truck transmission between the tractor's original transmission and differential, giving me a total of 16 speeds. The second transmission's input and output shafts were cut, as were the original transmission's input and shafts, so the second transmission's shafts could be welded to them. Angle brackets were bolted to the frame channels and connecting pieces were bolted to brackets and the second transmission. At the rear, angle brackets were brazed to the casing. I also ended up making 2 1/2-in. spacers with longer machine screws to bolt to the back end of the frame channel to get the transmission to fit properly. I then mounted the hydraulic pump off the tractor's Charlyn hi-lo hydraulic pack underneath the driver's seat instead of behind the transmission as it had been originally. I drive it with a #60 roller chain which runs on a 1 3/ 8-in. dia. sprocket running on the pto shaft. The chain runs through a hole I cut in a mounting platform, which I made of 1/4-in. plate. I installed a small shelf made out of plate above the pump and mounted a single-acting valve and double-acting valve on it. I installed an oil reservoir on another plate to the right and plumbed up the system, which is complete with an oil return line and pressure gauge.
