Increased oil volume from the larger gears and properly sized passages along with the pressure relief valve seat and seal from these oil pumps is essential for proper oiling system function
Eliminate common pressure and scavenge issues associated with the factory oil pumps
Precision-machined pressure relief valve and bore
Every pump is bench tested, the relief valve is seated and sealed to a minimum of 30 psi with full pop-off at 55-60 psi
Feuling M-Eight oil pumps have the groove machined on the back cover to accept the factory crank bearing seal
When matched to a Feuling cam plate, pumps reduce engine and oil temperatures, increase oil pressure volume, and scavenge volume on the return side to reduce build up of oil in the crankcase
Increase oil flow in and out of the engine with corrected tolerances, oil passages and larger geroter gears
High-flow 2.250" Chrome Moly gerotor gears
42% more scavenge volume with matched passages, port sizing and holes to the engine case
68% more oil volume to the crankshaft and connecting rod bearing
Magnet to help protect gears and pressure relief valve
More horsepower and torque to the rear wheel
M-Eight Twin-Cooled motors have 30% more pressure gear volume over stock and 53% more scavenge gear volume over stock
M-Eight oil-cooled motors have 27% more pressure and scavenge gear volume over stock
Billet 6061 aluminum with natural finish
