This is a high-performance gear pump designed to deliver precise hydraulic fluid flow and pressure for the main hydraulic system of Caterpillar wheel loaders and related equipment. It is manufactured using durable materials and to exact OEM tolerances, ensuring consistent operation and a longer service life than a worn pump exhibiting reduced output or internal bypass. Operators may experience sluggish or unresponsive hydraulic functions, such as boom or bucket movement, when this pump begins to fail.
Always verify with serial number before ordering.

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.
A failing 1396084 gear pump will initially manifest as a gradual loss of hydraulic power and slower implement speeds. If the issue progresses, hydraulic functions may become erratic or intermittently unavailable, impacting operational efficiency. Continued use with a degraded pump risks overheating the hydraulic oil and potentially damaging other system components.
Ensure the hydraulic system is completely drained and flushed to remove any debris before installing the new pump. Avoid forcing the pump onto the drive shaft; it should slide into place with minimal resistance.
When replacing this gear pump, it is advisable to inspect and replace the hydraulic filter element and check the condition of hydraulic hoses and fittings.
