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 will typically present as a noticeable loss of power and speed in all hydraulic functions, often accompanied by whining or grinding noises from the pump. If ignored, this can lead to complete loss of hydraulic power, rendering the machine inoperable and potentially causing further damage to other hydraulic components.
Thoroughly flush the hydraulic system and replace the main hydraulic filter before installing the new pump to prevent contamination. Ensure the pump shaft is properly aligned with the drive coupling to avoid premature bearing failure.
Always replace the main hydraulic filter and flush the hydraulic system when replacing the main hydraulic pump.
