Marshall 602 Crankshaft & Oil Delivery

The crankshaft is one of the most important parts of any combustion engine, requiring high fatigue strength and wear resistance as it circulates engine oil under pressure to a number of moving components, allowing the crankshaft to convert a linear to rotational motion with power equal to any task. Oil provides lubrication to the bearings, which is crucial for preventing friction.

Should the crankshaft or some part of the oil delivery system fail or become too worn over time, low oil pressure and friction can cause serious engine damage to your Marshall 602 tractor. Over time dirt ingress can cause scoring of the crankshaft bearings or the crankshaft itself. Here at Tractor Spare Parts Ltd we can help by offering undersized bearings, and an in-house crankshaft grinding service, we can get your crankshaft working again and with plenty more hours left on the clock. We often stock crankshaft bearings to 0.060” undersized, so even when you think your Leyland 4/98 crankshaft is past its best, we can work with you to get it working again.

We offer new oil pump for the Leyland 4/98 engine, as well as front and rear crank seals, which you might as well replace if you are in this area of your engine.

If you’re looking to repair the crankshaft or oil delivery system in your Marshall 602 tractor with the Leyland 498 engine, we have a wide range of parts and components to help you do so.
