FPLJ2601278 — Hydraulic Pump Gear 3028420 For Cummins Engine Ism Ism11 L10 M11 Qsm11 Volvo Excavator Ec360 Ec460

This hydraulic pump gear is a precision-engineered component within the hydraulic pump assembly, responsible for transmitting power and generating hydraulic flow. Manufactured to exacting standards, it offers superior wear resistance and dimensional stability compared to a worn gear with chipped teeth or excessive play. Operators might experience a loss of hydraulic system pressure, sluggish or unresponsive hydraulic functions, or unusual noises from the hydraulic pump if this gear fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A worn hydraulic pump gear may initially manifest as a slight decrease in hydraulic system performance or a faint whining noise from the pump. If left unaddressed, this can progress to significant loss of lifting capacity or boom/attachment speed, and potentially pump seizure. Continued operation risks severe damage to the entire hydraulic system, including hoses and cylinders, due to erratic pressure fluctuations.

Installation Tip

Thoroughly clean the inside of the hydraulic pump housing and ensure all mating surfaces are free of debris before installing the new gear. Never reuse old seals or gaskets; always install new ones.

Service Note

When replacing a hydraulic pump gear, it is highly recommended to inspect and replace the hydraulic pump seals and perform a full hydraulic system fluid and filter change.
