Jims Oil Pumps Gears

5 products — part of all Oil Pumps Gears

Jims oil pump gears for Harley-Davidson restore or improve oil flow within the lubrication system of your Big Twin or Sportster engine, ensuring correct feed and scavenge volumes across the full operating range. Oil pump gears are a precision wear item — as gear faces erode and running clearances increase over miles, oil pressure falls progressively below specification. Left unchecked, reduced oil pressure accelerates bearing wear, causes low-pressure warnings and eventually risks catastrophic engine failure at operating temperature. Jims machines their Harley-Davidson oil pump gears to tighter tolerances than OEM, with surface finishes that minimise wear-in and extend the service life of both the gears and the pump body they run in. Iron City Motorcycles, your authorised Harley-Davidson dealer in Leeds, stocks Jims oil pump gears as part of a comprehensive engine rebuilding programme.
