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

This is a hydraulic pump gear, a critical component within the hydraulic pump assembly that meshes with other gears to generate hydraulic pressure for the machine's functions. It is precision-machined to exact tolerances, ensuring efficient power transfer and longevity, unlike a worn gear with damaged teeth that causes erratic hydraulic performance. Operators may experience slow or unresponsive hydraulic functions, such as boom, stick, or bucket movements, if this gear is worn or broken.

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

The primary symptom of a worn hydraulic pump gear is a noticeable degradation in hydraulic system performance, such as sluggish or erratic operation of boom, bucket, and steering functions. If the gear teeth are significantly worn or broken, hydraulic pressure will drop, leading to a loss of power and potentially rendering the machine inoperable. Continued operation can cause further damage to the pump housing and other hydraulic components.

Installation Tip

Thoroughly clean the inside of the hydraulic pump housing and inspect for any scoring or damage before installing the new gear. Ensure the gear is properly seated on the shaft and meshes smoothly with the mating gear.

Service Note

Inspect the hydraulic pump housing, shaft seals, and filter for debris when replacing the hydraulic pump gear.
