Here’s how the installation went down…
Since we planned on some additional power options on this motor, we chose the S&S HVHP oil pump and a .585 S&S cam.
To begin the oil-pump installation process we first must clean and check all moving parts fitment to be assured everything fits and spins freely.
Next we insert one bolt that the oil-pump body slides onto as we align the HVHP gasket. The HVHP gasket is different than a traditional H-D gasket, so if you ever need to replace it, be sure to get the correct gasket for the HVHP oil pump.
Place the HVHP oil-pump housing over the gasket, onto the two bolts. Make sure not to tear the gasket material.
Hold the oil-pump pinion gear in place so the oil-pump drive shaft inserts into the pinion gear while placing the oil-pump body onto the mounting screws.
Next we insert the lower bolt that holds the HVHP oil-pump body onto the engine case.
Insert the top bolts through the oil-pump and into the engine case. Make sure to only hand-tighten these bolts at this time.
Verify the oil-pump pinion gear is on the drive shaft, and also verify the oil-pump gears are spinning freely inside the housing.
