We all know how important it is to keep cool when you’re riding your motorcycle on a hot day. The cooler you and your trusty steed are, the longer you can go, the more time you spend in the saddle, you get the point. For your motor, oil is the lifeblood of heat management. A good aftermarket pump like this one from S&S Cycle is like upgrading the heart that pumps that blood. Hence why we added one to this 1997 H-D Evolution powerplant. The S&S High Volume High Pressure (HVHP) oil pump kit provides 38 percent more oil supply volume, as well as increased oil pressure, and offers 61 percent more scavenging than stock 1992 and later Harley-Davidson oil pumps.
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.
