Product Introduction

As a next-generation core pressure boosting component tailored for heavy-duty diesel common rail systems, the 10R-7760 actuator pump breaks the traditional integrated pump body design logic by adopting a standalone structure without built-in feed pump. Equipped with compact small flange and precision 36-tooth drive gear, this unit is specially engineered to match medium and large displacement diesel power units used in construction machinery, industrial stationary engines and heavy mining equipment. Different from conventional combined pumps, it separates low-pressure fuel pre-supply and high-pressure pressure boosting physically, making the whole diesel oil circuit layout more flexible, while greatly reducing the failure rate caused by integrated component aging. It perfectly meets EU Stage IV and EPA Tier 4 emission control requirements, becoming a preferred replacement part for European and American diesel engine OEMs, professional repair garages and equipment end owners.

 

Core Technical Parameter Benchmarking & OEM Standard Calibration

 

The 10R-7760 strictly follows original equipment manufacturing dimensional tolerance and pressure calibration standards, with all performance indicators verified by professional diesel common rail test bench: Part Number is 10R-7760; structural configuration is small flange mounting, 36-tooth synchronous drive, no integrated feed pump; rated working rail pressure ranges from 1100bar to 1550bar, with instantaneous peak pressure up to 1650bar. The drive gear adopts carburizing and quenching process, with meshing accuracy controlled within IT5 level. The overall pump body uses high-strength cast aluminum alloy and wear-resistant alloy steel plunger pair, adapting to long-time high-load operation of diesel engines. It features full interchangeability with original parts, no secondary debugging needed after direct replacement.

 

Structural Design Advantages Decoded From Mechanical Matching Perspective

 

The small flange design of 10R-7760 is optimized for narrow engine compartment installation space of engineering vehicles, realizing compact assembly and stable fixed support. The 36-tooth gear ratio is precisely matched with engine crankshaft timing, ensuring synchronous power transmission and avoiding rail pressure fluctuation caused by speed mismatch. The biggest highlight of this model is the cancellation of the internal feed pump, which simplifies the internal structure of the pump body, reduces internal oil channel resistance, and effectively lowers the probability of internal blockage and oil leakage of diesel circuit. The built-in pressure regulating valve adopts high-frequency response design, which can quickly adjust diesel pressure in real time according to ECU signal, laying a structural foundation for stable combustion of common rail system.

 

 

Wide Application Scenarios For Heavy-Duty Diesel Equipment

 

10R-7760 36-tooth small flange actuator pump is widely compatible with mainstream heavy-duty diesel engines used in global engineering and industrial fields. It covers multiple series of crawler excavators, wheel loaders, road rollers, bulldozers, as well as stationary diesel generator sets and mining special power units. It is perfectly applicable to mainstream mid-range diesel engine models matched with construction machinery, suitable for after-sales maintenance replacement, engine overhaul and OEM supporting assembly. Its adaptive working environment ranges from low-temperature cold region to high-temperature dusty mining area, showing strong environmental adaptability of diesel power system accessories.

 

❓ Frequently Asked Questions (FAQ)

 

Q1: Why is the 10R-7760 designed without a built-in feed pump instead of an integrated structure?

A: The no-feed-pump split design separates low-pressure oil supply and high-pressure boosting, reduces internal failure points of the pump body, adapts to more diesel engine oil circuit layout schemes, and is easier for daily fault detection and partial maintenance.

Q2: Does the 36-tooth gear of 10R-7760 need professional timing calibration during installation?

A: The 36-tooth drive gear is preset with standard timing parameters, it can be installed directly in physical matching, but it is recommended to use a professional diesel common rail detector to verify rail pressure synchronization after installation.

Q3: What kind of diesel quality is most suitable for long-term use of 10R-7760 actuator pump?

A: It is recommended to use EU standard low-sulfur ultra-clean diesel with particle filtration precision above 3μm, inferior diesel will cause premature wear of plunger and pressure regulating valve, leading to common rail pressure instability.

Q4: Can 10R-7760 be used for modified diesel common rail power units?

A: Yes, its independent pressure boosting structure and stable pressure output are suitable for moderate power upgrade and common rail system refitting of engineering diesel engines, with strong compatibility of peripheral accessories.

Q5: What are the common early failure symptoms of a worn 10R-7760 pump?

A: Typical manifestations include weak diesel engine power, unstable idle speed, increased exhaust smoke, and obvious fluctuation of common rail pressure data detected by diagnostic instruments.

Q6: Is the small flange size of 10R-7760 universal for all same-class diesel pumps?

A: No, its small flange hole position and installation thickness are OEM-specific customized size, only compatible with matching designated diesel engine models, cannot be replaced with ordinary universal flange pumps at will.
