MCS Oil Pumps Gears

13 products — part of all Oil Pumps Gears

MCS oil pump gears give Harley-Davidson engine builders the replacement and upgraded pump gears needed to restore or improve the oil circulation system that keeps the engine lubricated under all operating conditions. The oil pump gear set is the heart of the dry-sump lubrication system used across Harley-Davidson Big Twin and Sportster engines, controlling both the feed side that delivers oil to the engine and the scavenge side that returns it to the tank. Worn or damaged pump gears cause reduced oil pressure, inadequate scavenging and accelerated engine wear — symptoms that become critical during sustained high-RPM riding. MCS supply pump gears machined to the dimensional tolerances required for correct meshing and efficient oil transfer, covering the key Big Twin and Sportster pump housings. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries MCS oil pump gears alongside a full engine lubrication and oiling system range.
