CATBearing & Bushing

6T4177 Bearing — Cat D11N D11R

This is a heavy-duty bearing designed for critical support roles in large mining and construction equipment, such as final drives and track systems. Manufactured to withstand extreme loads and operating conditions, it ensures reliable component function, unlike a worn bearing that can lead to excessive play, noise, and eventual component failure. Operators may observe increased track noise, binding, or a loss of drive power when this bearing begins to fail.

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

The first noticeable symptom of bearing failure is often a loud grinding or clunking noise from the final drive or track system, accompanied by increased vibration. If ignored, this can quickly lead to severe damage to the drive shaft and gears, potentially causing a complete loss of drive power. This poses a significant risk of extended equipment downtime.

Installation Tip

Thoroughly clean the final drive housing and shaft mating surfaces to prevent any abrasive material from compromising the new bearing's integrity. Never attempt to install the bearing by hammering it into place; use a hydraulic press or appropriate specialized tooling.

Service Note

Inspect the final drive shaft and housing for any signs of wear or damage, and ensure all seals are in good condition before reassembly.
