Rebuilding a Massey Ferguson 35 engine is a large and complicated task, but it is possible to do it yourself with the right tools and knowledge. First, you’ll need to remove the engine from the tractor, and then drain any oil or fluids from the motor. Next, you’ll need to remove the heads and valves, inspect them, and then remove the pistons, connecting rod and crank shaft. Once all of these parts have been removed, you’ll need to clean and inspect them, as well as measure and check all the bearing and seal surfaces.
Once all of this is done, you’ll need to reassemble the engine, replacing any worn or damaged parts. You’ll then need to install new pistons and rings, camshaft, valve springs, bearings and seals. After that, you’ll need to time the engine, set the idle speed, and then adjust the points, valves, and carburetor.
Once all of the engine components are in place, you’ll need to re-install the engine, making sure all of the lines, hoses, wires, and other attachments are properly connected. Finally, you’ll need to fill the engine with oil, and start the engine for final adjustments. With patience and the right tools, you can rebuild a Massey Ferguson 35 engine successfully.
