Description

What does an injector pump coupling do?

This injector pump coupling acts as a critical power-transmission component within the fuel system of heavy commercial vehicles. It transfers the rotational drive from the engine to the fuel injection pump while accommodating slight shaft misalignments. By absorbing torsional shocks and dampening vibrations, it ensures the pump operates in exact synchronization with the engine speed, which is vital for maintaining correct fuel injection timing.

Compatible Volvo engines and models

This component is compatible with several Volvo models including the F10, F12, F7, FL10, FL12, N10, N12, NL10, NL12, B10B, B10M, and B12. It is specifically designed to work with various engine families such as the TD70, TD71, TD100, TD101, TD102, TD103, TD120, TD121, TD122, TD123, D10A, and D12A. This broad compatibility makes it a reliable choice for diverse fleet maintenance needs.

Installation and maintenance guidance

To ensure proper engine performance and prevent fuel timing errors, technicians should inspect the coupling for signs of wear or excessive vibration during routine maintenance intervals. When replacing this component, it is essential to verify that the new part matches the specific engine code to maintain exact synchronization between the drive assembly and the pump.

Troubleshooting and system protection

Proper installation of this coupling helps protect both the fuel injection pump and the engine's drive train from sudden mechanical shocks. Maintaining a high-quality connection at this point is essential for preventing unplanned downtime in heavy-duty applications.

OE cross-reference

1300 01 051 (Injector Pump Coupling) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 479459.
