Marshall 702 Engine Block

In the engine block (or cylinder block) at the bottom end of the engine, the crankshaft spins, the camshaft is held, and the pistons move in the cylinder bores. On top of the engine block, the cylinder head allows the pistons to move up and down and turn the crankshaft.
One of the most common problems you may encounter with the Leyland 4/98 engine fitted to the Marshall 702 tractor, is porous liners where the coolant and the oil mix and you observe milky oil in the sump. If you have porous liners this can be diagnosed by a pitting that you can feel with your fingers on the inside of the liner about 1/3 of the way down. This indicates that it is time for a new engine rebuild kit for your engine, and we can help you. We offer complete engine rebuild kits, as well as all the individual components, so we can offer you exactly what you need based on your requirements and your budget. It is recommended that you replace all four pistons and liners at the same time, but there will be occasions when one liner is needed, or just pistons rings replaced etc. We can work with you to ensure that we make up the correct engine kit based on your serial number, or offer you the individual parts that you need based on your tractor engine serial number and your requirements.
Whatever you need, we stock a wide range of parts to help with repairs and restoration projects. Every spare part and component is expertly quality control checked by our team in-house at Tractor Spare Parts Ltd to ensure longevity and performance upon installation.
