FAQ: C15 Acert, C15 & 3406E Black Series Oil Pump (4N8734 / 0R9449)
What Caterpillar engines does the 4N8734 Black Series oil pump fit?
The HHP Black Series Oil Pump (part number 4N8734 / 0R9449) is a direct-fit replacement for three Caterpillar engine families: the 3406E, the C15, and the C15 Acert. If you’re unsure whether this pump is compatible with your specific engine configuration, Highway & Heavy Parts recommends providing your Engine Serial Number (ESN) or VIN so their team can verify fitment before shipment — preventing a costly wrong-part scenario.
What are the signs that my Caterpillar C15 or 3406E oil pump needs to be replaced?
The two most common warning signs of a failing oil pump on a Caterpillar C15, C15 Acert, or 3406E are unusual engine noise and low oil pressure readings. As the oil pump wears down, it loses its ability to maintain adequate lubrication throughout the engine. Left unaddressed, a failing oil pump can escalate into severe engine damage — making early replacement critical to avoiding a much more expensive repair.
What OEM part numbers does the HHP 4N8734 Black Series oil pump replace?
This Black Series oil pump is a direct replacement for a wide range of OEM and aftermarket part numbers, including: 4N-8734, 0R-9449, 0R-9057, 0R-4999, 0R-3538, 0R-9449, 1614113, 161-4113, 20R-2134, 6N-1030, 6N-4578, 7C-1531, 7W-2356, and several others including AK4N8734, M4N8734, FP1614113, and USOP8734. If you’re cross-referencing from an old invoice or parts catalog, chances are this pump covers it.
Is this a new oil pump or a remanufactured one?
This is a brand-new oil pump — never used and never remanufactured. Highway & Heavy Parts does not sell rebuilt or remanufactured components in the Black Series line. Every unit ships as a new part, which also means there is no core charge required when you order.
How does the Black Series oil pump compare to OEM Caterpillar quality?
The Black Series oil pump is engineered to meet or exceed OEM specifications for the Caterpillar 3406E, C15, and C15 Acert. It is manufactured in an ISO 9001:2015 certified facility using hard-wearing materials designed to withstand the demands of heavy-duty diesel operation. HHP positions it as an upgraded replacement — delivering OEM-level (or better) fit and function at a significantly lower price than a genuine Caterpillar oil pump.
What warranty comes with the C15 / 3406E Black Series oil pump?
The Black Series Oil Pump (4N8734 / 0R9449) carries a 1-Year Unlimited Mileage Parts & Labor Warranty. This covers both the part itself and the labor associated with a warranty repair, providing meaningful protection for owner-operators and fleet managers alike. Note that this differs from the 3-year warranty offered on the Black Series rebuild kits, so be sure to register your purchase accordingly.
How quickly will this oil pump ship, and how is it packaged?
Orders placed by 2:00 PM EST Monday through Friday on in-stock items ship the same day. The pump ships in a 15″ × 8″ × 7″ box weighing approximately 22.68 lbs, making it eligible for standard UPS or FedEx ground delivery with nationwide coverage. Expedited shipping options may also be available — contact HHP at 844-215-3406 for time-sensitive needs.
Can I get technical help selecting or installing this oil pump?
Yes. Highway & Heavy Parts has ASE-certified diesel technicians on staff available to assist from diagnosis through delivery. Whether you need help confirming this is the right pump for your engine serial number, want guidance on installation, or have questions after the part arrives, support is available by phone at 844-215-3406, text at 844-390-1339, or via the contact form on their website. This level of in-house technical support is one of the key differentiators HHP offers over general parts retailers.
