This is a high-pressure hydraulic axial piston pump, essential for powering the main hydraulic systems of articulated dump trucks. It is manufactured to rigorous standards, ensuring superior durability and performance compared to worn or damaged units. Failure often manifests as sluggish hydraulic operation, loss of lifting or steering power, and audible whining noises from the pump.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Initial signs of a failing hydraulic pump include a noticeable decrease in system responsiveness and increased operating temperatures. If ignored, the pump's output will continue to diminish, leading to severely impaired machine functions. Continued operation with a failing pump risks damage to other hydraulic components due to contaminated fluid or lack of proper lubrication.
Thoroughly flush the hydraulic system to remove any contaminants before installing the new pump. Avoid overtightening the mounting bolts, as this can distort the pump housing and cause leaks.
Inspect the hydraulic fluid and filter for signs of wear particles, and check all hydraulic hoses and fittings for leaks during pump replacement.
