1u-2664-0r-1495 Hydraulic Pump Cartridge — Cat 3408

This is a CAT Hydraulic Pump Cartridge, a precision-engineered assembly that forms the core of the hydraulic pump, generating flow and pressure for the machine's functions. It consists of precisely matched gears or pistons within a housing, ensuring efficient fluid transfer, unlike a worn cartridge with scored surfaces or worn seals. Operators will typically observe a loss of hydraulic power, slow or erratic operation of implement controls, and potentially whining noises from the pump when a cartridge 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

The primary symptom of a failing hydraulic pump cartridge is a noticeable reduction in the speed and force of hydraulic functions. If ignored, this can progress to intermittent loss of hydraulic power, making equipment operation sluggish and unresponsive. Ultimately, a severely worn cartridge can lead to complete loss of hydraulic system pressure, rendering the machine inoperable.

Installation Tip

Thoroughly clean the inside of the hydraulic pump housing and ensure all internal passages are clear of debris before installing the new cartridge. Never mix old and new seals or O-rings; always use the complete set provided with the new cartridge.

Service Note

Always replace the hydraulic filter and ensure the hydraulic fluid is clean and at the correct level after installing a new pump cartridge.
