Marshall 704 Crankshaft & Oil Delivery

The crankshaft requires high fatigue strength and wear resistance as it circulates engine oil under pressure to its many moving components, converting linear to rotational motion. Thankfully despite wear over time due to dirt ingress, the crankshaft can be ground to accommodate undersized crankshaft bearings, and we are able to offer underside crankshaft bearings in 0.010” (ten thou) increments, with some sizes also available in 0.005” (five thousands of an inch) increments – search below for the available sizes). We are also able to regrind crankshafts if you are unable to do this locally. We can even help with shipping of your crankshaft to us and in return so that we are able to offer a one-stop solution for the rebuild of your Leyland 4/98 TT engine in your Marshall 704 tractor.
If you experience low oil-pressure in your Marshal 704 it may be that your oil pump has worn and is in need of replacing. We are able to provide you with a new oil-pump, part number 86k1585, which will get your oil pressure back up to acceptable range. Did you know that we have a You Tube channel and a Facebook page that has a lot of useful information on fitment of parts? One of these videos shows how to check the backlash between the driven gear and the driving gear. Check it out here.
Should the crankshaft or some part of the oil delivery system fail or become worn, low oil pressure and friction can cause serious damage to the engine in your Marshall 704 tractor. The crankshaft bearings are not parts of the standard engine kit that we offer as they come in a range of undersized bearings, meaning that you can buy them alongside the engine kit for a full refurbishment of your engine.
If you’re looking to replace or repair the crankshaft or oil delivery system in your Marshall 704 engine, we have everything you need to do so! Our range includes washers, pumps, crank seal housings, drive gears, bearings, connecting rods and much more!
