CUMMINS ISB 6.7L Oil Pump For Sale (Part 3971544)
About This Cummins ISB 6.7L Oil Pump
This is a good, used oil pump for the Cummins ISB 6.7L, carrying part number 3971544. The oil pump circulates pressurized lubricant through the engine to protect bearings, journals, valve-train parts, and other moving surfaces. Excessive wear, internal damage, or a failed drive can cause low oil pressure and quickly place the engine at risk of serious damage. Pump capacity, pickup arrangement, mounting, and drive design are specific to the engine, so fitment must be confirmed against the exact application. Compare the existing component, page photos, and any listed part number before ordering. The part is inspected and tested before it ships, identified by its stock number (321852), and backed by included warranty coverage. Freight ships nationwide, quoted to your delivery ZIP. Use the page photos and listed details to compare it carefully with the component being replaced before purchase. Have your engine's year, make, model, and application ready and call (800) 696-5459 to confirm fitment before ordering.
