E.R.T. Products introduces the PJ-2 Series Shovel-Evo Pro-Just. The PJ-2 is designed for Evolution & late Shovelhead stock ('81 - '99) and most aftermarket oil pumps. The PJ-2SS is specifically designed for the HVHP oil pumps. PJ-2 Pro-Justs are made from billet aluminum and have a smaller outer diameter so they will fit inside of the oil pumps counter bored pressure relief valve of later model pumps.
The PJ-2SS is specifically designed for the HV/HP oil pumps. At the neutral setting ( 1/4" between thumbscrew and top of alum body), the oil pressure relief valve spring is less compressed resulting in lower start up oil pressure When the normal warm operating temp. is reached, the PJ-2SS can then be adjusted to increase warm engine oil pressure and stay within factory specs. All HV/HP oil pumps.
The Pro-Just works will all 3 springs from our SP-1 Superpump-kit along with the stock harley oil pressure relief spring. You have the advantage of the whole range of springs to enable correct factory oil pressure!
Pro-Just bodies are made from “Billet” 6061 aluminum and are counter bored to accept two o-rings. The first o-ring seals around a knurled stainless steel thumbscrew that provides the adjustment. The second o-ring ensures that the Pro-Just seals properly in the oil pump's pressure relief valve.
Adjustment of the oil pressure is done with the engine running. Turning the thumbscrew clockwise increases oil pressure, counter clockwise decreases oil pressure.
As you are dialing in your oil pressure you will notice that it only takes a small turn to watch the needle on your gauge move up or down. Once desired oil pressure is achieved, no further adjustment should be necessary.
The PJ-2 neutral setting is 1/8” from the top of the Pro-Just body to the bottom of the thumbscrew head. The PJ-2SS is 1/4" for the neutral.
NEVER adjust above neutral setting!!!
Once proper oil pressure is reached, measure the distance between the top of the aluminum body and the bottom of the thumbscrew. Remove and clean the thumbscrew, apply a couple of drops of BLUE Loctite and reassemble. This will ensure that your adjustment is maintained!!!
The Pro-Just is an adjustable pressure relief cap that allows the precise adjustment of oil pressure. Pro-Just bodies are made from “Billet” 6061 aluminum and are counter bored to accept two o-rings. Includes the "blue" Super-Pump spring.
