246-4486 Hydraulic Piston Pump — Cat Motor Grader 14M 16M

This is an OEM-specification CAT Hydraulic Piston Pump, a critical component responsible for generating high-pressure hydraulic flow to operate various machine functions. It is manufactured to meet CAT's rigorous durability and performance standards, offering superior longevity over a worn or failing pump. Operators will typically observe sluggish or erratic hydraulic movements, such as slow blade lift or drift, when this pump begins to degrade.

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 first indication of a failing hydraulic piston pump is often a noticeable decrease in the speed and responsiveness of hydraulic functions. As the problem progresses, hydraulic systems may become erratic, with functions failing to hold position or operating with significant lag. Continued operation risks severe damage to other hydraulic components due to insufficient flow or pressure.

Installation Tip

Thoroughly flush the hydraulic system and replace the hydraulic filter before installing the new pump to prevent contamination. Ensure the pump shaft is properly aligned with the drive coupling to avoid premature wear.

Service Note

When replacing the hydraulic piston pump, it is essential to inspect and replace the hydraulic filter and check the condition of the hydraulic fluid.
