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.
Initial signs of a failing hydraulic pump include a noticeable decrease in lifting capacity and slower boom/bucket movements. If ignored, the pump's performance will continue to degrade, leading to intermittent loss of hydraulic function. Continued operation with a failing pump risks overheating the hydraulic oil and damaging other system components.
Ensure the hydraulic system is completely flushed and clean before installation to prevent contamination. Avoid overtightening the mounting bolts, as this can distort the pump housing and lead to premature failure.
Inspect the hydraulic oil for signs of contamination or degradation, and replace the hydraulic filter element when installing a new pump.
