Allis-Chalmers Model B and C Parts

This page contains engine parts

These parts are from both Allis Chalmers B and C tractors. Many are interchangeable, but some are specific to on or the other. If you are unsure, ask and I will verify if it will fit your tractor.



Marvel Schebler TSX305 carburetor, correct original equipment for hand start B or C, this carb has been disassembled, thoroughly cleaned and checked, then reassembled with a new gasket. It is ready to bolt on to your tractor and go to work!, $180





AM2916-10 block with cranshaft, main bearings, camshaft, lifters, sleeves, pistons, connecting rods, oil pump, and crankshaft pulley. The only problem noted is the comonly found cracks on top of the block and between the sleeves. These can be sealed with a good sealant on the head gasket, but I have discounted the price of individual parts to include the block at no charge, the block is as-is. Due to weight, the block must either be picked up here or I can give you a quote on truck freight shipping. $325
