Cat Backhoe Loader Hydraulic Pump Replacement: 100-3259 (1003259) For 416b/426b/428b/436b/438b

Cat 416B Hydraulic Pump & Double Gear Pump Product Details

This hydraulic pump is specially designed for Caterpillar backhoe loaders. Among them, the cat 416b hydraulic pump is an exclusive adaptive pump body for the Cat 416B model. Through original factory dimension calibration and performance testing, it can perfectly replace the aged main pump, ensuring stable hydraulic power output of the equipment in working conditions such as earthwork operations and material handling. As a core component of the efficient hydraulic transmission solution, the double gear pump adopts a double-gear meshing structure, featuring dual independent oil supply capabilities that can drive multiple hydraulic actuators simultaneously. The Cat Replace Pump is designed with the concept of "plug-and-play" and complements the cat 416b hydraulic pump, providing Cat equipment users with a convenient and reliable replacement option to solve the efficiency pain point of equipment shutdown for maintenance.

Precise Adaptation and Dual-Circuit Oil Supply: The cat 416b hydraulic pump is equipped with a pressure compensation valve, which can automatically adjust the output pressure according to the operating load of the Cat 416B model to avoid power overload. Its operating stability is 20% higher than that of ordinary replacement pumps. The double gear pump uses high-strength alloy gears and precision bearings; when the double gears run synchronously, the volumetric efficiency reaches over 93%, and it can provide stable oil pressure for the boom and stick at the same time. It is especially suitable for the multi-action coordination scenarios covered by the Cat Replace Pump, such as the composite excavation operation of the Cat 416B. In addition, the cat 416b hydraulic pump also optimizes the oil inlet channel design to reduce the flow resistance of the oil, further improving the power transmission efficiency.

Durability and Replacement Convenience: The housing of the double gear pump is made of HT300 cast iron material. After high-frequency quenching treatment, its surface hardness reaches above HRC50, the wear resistance is significantly improved, and the service life is extended to more than 6,000 hours. The Cat Replace Pump strictly follows Caterpillar's original factory interface standards. Whether it is the cat 416b hydraulic pump or other types of replacement pumps, there is no need to modify the equipment's hydraulic circuit. Users can complete the replacement in only 30 minutes, greatly shortening the shutdown time. At the same time, the double gear pump is equipped with a dust-proof sealing structure, which can effectively block dust and impurities from entering the pump body, reducing the risk of failure and adapting to the outdoor complex operating environment of the Cat 416B.

In terms of installation, the cat 416b hydraulic pump is accompanied by an exclusive installation kit, including a sealing gasket, fastening bolts (preload force: 55-60 N·m) and an installation manual, making it easy for novices to operate. The double gear pump is provided with a positioning pin design to ensure accurate alignment with the equipment's hydraulic interface and avoid oil leakage caused by installation deviation. All Cat Replace Pump series products (including the cat 416b hydraulic pump) undergo no-load test run testing before leaving the factory, ensuring that they can be put into use directly after installation without additional debugging.

The Cat hydraulic pump adopts a standardized interface design, and its installation dimensions are completely consistent with the original factory accessories. Users can follow the instruction manual to replace it by themselves, saving maintenance man-hours. For users of the main pump cat 320b, we provide an exclusive installation guidance video, which details key steps such as bolt tightening torque (85-90 N·m) and oil circuit connection sequence, reducing installation difficulty. At the same time, both the high flow hydraulic pump and all Cat hydraulic pump products enjoy a 12-month warranty period. If there are quality problems within the warranty period, free replacement or repair services will be provided to ensure users have no worries during use.?

Original Factory Standard Quality: All axial piston hydraulic motors have passed ISO9001 quality system certification, with performance parameters consistent with Cat's original parts, and can be directly used as replacements;?

In-Stock Core Models: Hot models such as 312/315/320 are in stock all year round, enabling same-day order placement and fast delivery;?

Full-Process Technical Support: Provide one-on-one professional engineer services from selection, installation to maintenance, solving users' worries.?
