Product Description

Product Overview

The VE pump head drive shaft (Part Number: 1 466 100 401) is a critical high-speed rotating transmission component designed for precision diesel fuel systems. Before leaving the factory, each unit undergoes rigorous dynamic balancing verification to effectively reduce vibration during high-speed operation. This prevents fuel injection irregularities and ensures a smooth engine power output.

Performance Focus: By delivering stable power transmission, it enables the VE pump to precisely control fuel injection volume and timing, enhancing fuel efficiency while minimizing power loss.

As a standardized OE part, its specifications closely match specific VE pump models, allowing for direct replacement during repairs. Its high compatibility facilitates rapid resolution of equipment downtime caused by drive shaft failure.

Frequently Asked Questions
Which specific VE pump models is the 1 466 100 401 compatible with?
This drive shaft is designed to match multiple VE pump models including 8111302006, 5001836837, 7701045296, and 42530259, widely used in diesel engine fuel injection systems.
What are the core technical specifications?
The core specifications are Φ20×128, meaning a shaft diameter of 20mm and a length of 128mm. The OE code 1466100401 is the primary identifier for procurement.
Why might the engine vibrate after installation?
This is usually caused by improper shaft alignment (angular deviation exceeding 0.5°) or detachment of balance weights. We recommend recalibrating the installation angle or performing a dynamic balancing test.
What causes abnormal noises during operation?
Common causes include worn universal joints, inadequate lubrication of spline assemblies, or excessive clearance at the VE pump interface. Check these areas and replenish with specified grade grease.
What is the expected service life and how can I extend it?
Typical service life is 80,000–100,000 km. To extend this, regularly lubricate universal joints and splines, avoid prolonged overloading, and perform dynamic balancing inspections every 20,000 km.
What are the risks of not replacing a damaged drive shaft?
Short-term risks include reduced fuel precision and power loss. Long-term, severe vibration can damage the VE pump and bearing housing, potentially leading to total engine shutdown and high repair costs.
