CATBearing & Bushing

6K4487 Bearing-Needle — Cat 814 815

This is a needle bearing designed to accommodate high radial loads within a compact space, commonly used in transmissions and pivot points. It is constructed from high-grade steel to withstand significant stress and wear, offering superior longevity over a worn bearing that would exhibit reduced load capacity and potential scoring. Operators may observe increased play, binding, or unusual noises during operation when this needle bearing is failing.

Installation & Application Notes

Never strike bearings directly — use a bearing press or driver set. Heat housing (not bearing) to ease installation. Replace bearings in sets where applicable. Check housing bore diameter before fitting — out-of-round bores destroy new bearings.

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

Failure Symptoms

Early indications of failure include increased noise and vibration during operation, particularly under load. If ignored, the needle cage can fail, leading to roller damage and potential scoring of mating surfaces. This can result in component binding and significant damage to the surrounding drivetrain.

Installation Tip

Ensure the housing and shaft surfaces are perfectly clean and free of any burrs or debris before attempting installation. Never use a hammer or pry bar to install needle bearings; use a proper press or driver tool to apply even pressure.

Service Note

Inspect the lubricant for metal particles, which can indicate bearing wear, and check the shaft surfaces for scoring.
