Basic Parameters & Introduction
This heavy-duty high-precision hydraulic main pump assembly has a core original part number of 266-7954 (also written as 2667954), and is fully compatible with and replaces part numbers 247-8992/2478992. As the core heart of power transmission, this assembly is specially designed for Caterpillar's classic high-efficiency excavators, perfectly matching 30 ton main core models such as CAT E330D/330D L. The product is designed based on first principles for heavy-duty fluid mechanics, ensuring absolute certainty of ultra-high pressure and high flow output. The physical dimensions of the product packaging are approximately 810mm × 430mm × 470mm, with an overall net weight of approximately 198kg. The original factory standard position is connected.

Maintenance Tips
"Daily inspection (every 10 hours): Mandatory inspection of the main pump shaft seal, proportional solenoid valve, and high-pressure pipe opening before starting work to eliminate any trace leakage hazards.

First running in period (50 hours of operation): Before the new pump runs at high load, the hydraulic return oil filter element and the pilot high-precision filter element must be forcibly replaced after running for 50 hours to thoroughly filter out the initial trace debris.

Regular mandatory replacement (every 500/2000 hours): replace the entire hydraulic filter element of the vehicle every 500 hours; The oil tank must be thoroughly cleaned and the original factory standard anti-wear hydraulic oil replaced every 2000 hours (or up to 1 year). Under broken or harsh working conditions, the cycle is forcibly halved."

Installation Tips
"Extreme cleaning: Noise reduction and dust removal treatment are required for the unpacking and installation environment. All hydraulic pipeline joints and electrical control plugs must be thoroughly cleaned with specialized cleaning agents before being connected to a new pump, and any foreign objects are strictly prohibited from entering the pump body.

Forced oil filling (core pit avoidance): After the main pump assembly is lifted in place and before starting the engine, clean hydraulic oil must be filled from the oil injection/exhaust port on the top of the main pump. It is strictly prohibited to start dry grinding, otherwise the internal rotating components will undergo irreversible physical erosion within 3 seconds of ignition.

Low pressure exhaust transition: After the first ignition, the system is forced to idle at low pressure for 10-15 minutes for automatic exhaust and thermodynamic adaptation. The working load can only be gradually applied after the oil temperature and pressure are normal."
