Description
Cummins 6BT / 4BT Oil Pressure Regulator and Relief Valve Kit
- 1 x Oil pressure regulator Plunger
- 1 x oil pressure regulator spring
- 1 x oil pressure regulator cap and O ring
- 1 x oil pressure relief
Low oil Pressure, check your regulator spring aand also check your plunger for signs of galling or wear – could stick open causing low oil pressure.
Pressure relief reduces flow to oil filter when pressure too high – can lower oil pressure when spring loses tension.
Replace all these parts together to ensure healthy oil pressure in your 4BT / 6BT.
