Denso HP4 Pump Supply Pump Position Pin

1.Product Introduction

The Denso HP4 pump supply pump position pin is a small but critical component within the Denso HP4 high-pressure fuel pump system. It plays a role in ensuring the proper alignment and positioning of the supply pump within the fuel system.

Functions of the Supply Pump Position Pin:

1. Ensures Proper Alignment

   • The position pin helps in correctly aligning the supply pump with the camshaft or other driving components within the HP4 fuel pump assembly. Proper alignment is crucial for maintaining the precise timing of fuel delivery.

2. Prevents Rotational Misalignment

   • The pin acts as a locator to ensure the supply pump stays in the correct orientation. Without this pin, the pump could shift slightly during operation, leading to incorrect fuel pressure regulation and improper fuel injection timing.

3. Secures the Pump in Place

   • During operation, the fuel pump experiences high pressure and vibrations. The position pin helps secure the supply pump in its designated position, preventing any unintended movement that could affect performance.

4. Aids in Assembly & Maintenance

   • The position pin serves as a reference point during pump installation or maintenance, ensuring technicians install the supply pump correctly every time.
