MCS Oil Pump Parts

40 products — part of all Oil Pump Parts

MCS oil pump parts cover the Harley-Davidson lubrication components most often needed during engine work, from individual check valves and gears through to full rebuild provisions for machines where the pump has accumulated serious mileage. The MCS catalogue reaches back into classic Harley-Davidson territory — XL Sportster engines from 1972 through 1976, the later 1977 to 1990 Sportster generation, and Big Twin platforms from the pre-Twin Cam era stretching as far back as the 1930s. Whether you are refreshing the oil pump on a 1970s Ironhead Sportster, restoring correct oil pressure on a Big Twin Evolution, or sourcing service parts to keep a classic Harley-Davidson running reliably, MCS provides practical aftermarket coverage across decades of the marque's history. Maintaining healthy oil pressure is non-negotiable for engine longevity, and having the right pump components available from a single trusted supplier simplifies that work considerably. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, makes the MCS range available to UK riders through Iron Stable. Browse the full MCS Oil Pump Parts range below.
