Oil pressure is the absolute lifeblood of your engine. When you are rebuilding a B47 block after a bottom end failure or timing chain snap, reusing a scored or contaminated oil pump is a guaranteed way to ruin your hard work. We provide a genuine, salvaged OEM alternative that delivers factory reliability without the massive dealership price tag.

This is a genuine BMW engine oil pump and internal balance shaft assembly, manufactured by OEM supplier SHW. We have pulled this straight from a running donor B47 engine. It is supplied exactly as pictured, complete with the drive sprocket, internal balance shafts and the black plastic oil pickup tube/strainer (Part Number: 1141 8513665).

Before shelving, every pump goes through a thorough visual bench inspection. We check the sprocket teeth for damage, ensure the internal shafts rotate smoothly without binding, and verify the housing is free from cracks or severe scoring. It is a heavy duty, proper component ready to be bolted straight into your sump.

Complete Assembly: includes the oil pump, internal balance shafts, drive sprocket, and pickup tube.
