This charging pump assembly is critical for supplying pressurized hydraulic fluid to the main hydraulic pump and other auxiliary systems. It ensures adequate flow and pressure for smooth operation of all hydraulic functions. A malfunctioning charging pump can lead to a loss of hydraulic power, slow cycle times, and potential cavitation damage to the main pump.

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 charging pump often presents as a whining or groaning noise from the hydraulic system, especially under load. This can progress to slow or jerky operation of hydraulic functions and a noticeable drop in system pressure. If left unaddressed, it can lead to premature wear or failure of the main hydraulic pump.
Before installation, thoroughly clean the hydraulic lines that connect to the charging pump to prevent debris from entering the new unit. Ensure the pump shaft is properly aligned with the drive mechanism to avoid premature seal failure.
When replacing the charging pump, inspect the main hydraulic pump for signs of cavitation damage and check the hydraulic filter for any unusual wear particles.
