PJ-2 Series Shovel-Evo Engines

Adjustable Oil Pressure

E.R.T. Products introduces the PJ-2 Series Shovel-Evo Pro-Just. The PJ-2 is designed for Evolution & late Shovelhead stock and most aftermarket oil pumps. The PJ-2 has a smaller outer diameter so it will fit inside of the oil pumps counter bored pressure relief valve of later model pumps. (81-99)

Advantage Pro-Just

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!

American Made

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. 


Adjusting the Pro-Just

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. 

NEVER adjust above neutral setting!!!

Recommended

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!!!

Oil change & oil pump

If time has elapsed since your last oil change, now is a good time to change your oil and your filter. This will effect your oil pressure and engine life.

If your oil pressure reads 0 p.s.i. before & after installing the Pro-Just, please check your oil pump completely for any broken keys or gouged gear pockets!
