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.
The first indication of a failing hydraulic pump is often a noticeable decrease in the speed or power of hydraulic functions, such as the boom, stick, or bucket. This may be accompanied by unusual whining or grinding noises originating from the pump area. If left unaddressed, the pump can overheat and seize, leading to a complete loss of hydraulic power and potential damage to other system components.
Thoroughly flush the hydraulic system and replace all hydraulic filters before installing the new pump to prevent contamination. Ensure the pump shaft is correctly aligned with the drive coupling to avoid premature wear.
Replace all hydraulic filters and inspect the hydraulic fluid reservoir for cleanliness when installing a new hydraulic pump.
