This is a primary hydraulic pump, essential for generating the high-pressure fluid flow required to operate the excavator's main functions like boom, stick, and bucket actuation. Manufactured to meet rigorous OEM standards, it ensures consistent performance and longevity, unlike a worn pump that may suffer from reduced efficiency and internal leakage. Operators may experience slow or erratic hydraulic movements, a loss of lifting capacity, or audible whining noises from the hydraulic system when this pump is failing.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A failing hydraulic pump may initially manifest as a reduction in the speed and power of hydraulic functions. If operation continues, the pump's internal wear will worsen, leading to inconsistent performance, potential overheating, and increased risk of contamination in the hydraulic oil. This can ultimately lead to damage to other sensitive hydraulic components.
Thoroughly flush the entire hydraulic system, including lines and cylinders, before installing the new pump to remove any residual contaminants. Ensure the pump shaft is properly aligned with the drive coupling to prevent premature wear on both components.
Inspect hydraulic fluid for contamination, replace the main hydraulic filter, and check all hydraulic hoses and seals for wear or leaks.
