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 failure include a noticeable decrease in hydraulic system speed and lifting capacity. If left unaddressed, the pump's performance will continue to degrade, leading to intermittent operation and potential overheating of the hydraulic fluid. Continued operation with a failing pump risks damage to other critical hydraulic components.
Thoroughly flush the hydraulic system to remove any contaminants before installing the new pump. Avoid overtightening the mounting bolts, as this can distort the pump housing and cause premature failure.
Inspect hydraulic fluid and filters for contamination; replace if necessary, and check hydraulic hoses and fittings for leaks.
