FEULING OIL COOLED oiling system kits combine all the needed components to finish your Milwaukee Eight engines oiling system under 1 Part #, available in HP+ or RACE SERIES kits. FEULING oiling system kits increase oil pressure, oil volume, engine oil flow and return oil scavenging
Quieter and smoother engine operation 27% more pressure and scavenge gear volume over stock 42% more scavenge volume through port sizing, matched passages and holes to the engine case 68% more oil volume to the crankshaft and connecting rod bearing 15-25 degree cooler engine temperatures 15-30 degree cooler oil temperatures 10-30 more PSI of oil pressure Reduces wet sumping, blow by and oily air cleaners Test results show 2 HP gain and 2 ft/lbs of TQ gain to the rear wheel on Milwaukee Eight
NOTE: FEULING test results show as much as 50% reduction of engine sump oil level.
INCLUDED:a billet 7075 hard anodized oil pump which is 50% harder and stronger than the factory pump holding tighter tolerances under temperature. RACE SERIES M-Eight oil pumps have deeper scavenge kidneys when compared to the HP+ kidneys for increased scavenge volume. RACE SERIES hydraulic lifters have a full .200 of total travel designed with a slower bleed down rate to handle heavy valve spring pressures, increase engine RPM before valve float and feature increased roller clearance for steep ramped camshafts and clearance for the Milwaukee Eight camshaft front exhaust lobe flange. Kits include a RACE SERIES oil pump, RACE SERIES lifters, HIGH FLOW camplate and cam installation kit, cam bearing, cam/crank bolts and washers, engine and fastener assembly lube.
The FEULING oil pumps are bench tested, the relief valve is seated and sealed to a minimum of 30 psi with full pop off at 55-60 psi. The 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. The FEULING oil pump and camplate combination eliminate common pressure and scavenge issues associated with the factory oiling systems.
Due to the mass call volume & inquires with requests for the M-Eight oil pump back cover O-ring/seal groove, weve added the groove! (5/11/21). Although Feulings in house testing on healthy engines did not show a benefit. The O-ring may have potential benefits in certain circumstances such as engines with higher cylinder leak down, poor subseal O-ring seal, raised sump hole & or sump plug (see M8 PRO TIP below) & looser lifter to lifter bore clearances.
Optional FEULING X ARP bolt kit available for the HIGHFLOW Camplate and HP+ or RS oil pump combo. ARP bolts for oil pumps 7018, 7019, 7020 & 7021 do not use washers. You can see the Bolt Kit at this LINK.
OIL LEVEL NOTE - DO NOT OVERFILL OIL TANK It is important to get the correct hot oil level in your bike. See the video below to understand how to Check Hot Oil Level in your bike.
Note: The M-Eight oil pick up port is on the right side of the engine. Letting the bike idle or warm up on the kickstand will naturally fill the engine case and skew the oil level in the tank.
We recommend the following steps to achieve proper oil level: 1. Check cold oil level. 2. Ride the bike until operating temperature is reached. (210-230 F) 3. Shut the bike off while still in the upright position. (This insures an accurate reading) 4. Once the bike is on the kickstand check oil level. 5. Add or remove oil as needed.
