5011336R91 | Genuine International® High-Pressure Oil Pump 12CC

Description and Purpose:

This International High-Pressure Oil Pump is a OEM component designed for Navistar Maxxforce DT 6.7L HEUI diesel engines. Part Number: 5011336R91. Condition: New. As a vital part of the HEUI injection system, it builds the necessary oil pressure to activate fuel injectors. This pump is used in heavy-duty commercial applications, including International 4300, 4400, DuraStar, WorkStar, and IC Bus models from 2007 to 2010, ensuring consistent fuel delivery and engine stability. Cross reference: 5011335R91.

Why Replacement is Important:

Aging or failing oil pumps can no longer provide the pressure needed to operate injectors efficiently, resulting in poor combustion, hard starts, or even complete engine failure. Replacing the unit prevents costly downtime and engine wear.

Impact on Vehicle Performance:

Without proper oil pressure, fuel injection suffers, leading to reduced torque, poor idling, and engine hesitation. A new pump restores normal engine behavior and maintains performance in demanding driving conditions.
