Engine Oil Pump For Cummins Dodge 4BT 3.9L & 6BT 5.9L (1989-2002) | Replaces 3937404, 3930337

Alright, so you're working on a classic Cummins 4BT or 6BT—maybe for a swap, maybe for a truck.

Either way, you need oil pressure, and this pump delivers.

It's a direct replacement for those hardworking 3.9L and 5.9L engines from 1989 through 2002.

This Arko Tractor Parts pump (MPN 71198) replaces the OEM numbers 3937404 and 3930337.

Brand new, never used, still in the box.

It's a performance part, meaning it's built to keep that diesel running strong.

No mounting hardware included, just the pump itself with a nice fresh finish.

Fits way more than just Dodge too—think Ford trucks, International, Freightliner, JCB, marine applications, generators, you name it.

If you've got a piece of equipment with one of these engines, this pump is likely what you need.
