3648484 Bearing — Cat 980K 980K HLg

This is a high-performance bearing designed to support heavy rotational loads and reduce friction in the power train and undercarriage of large Caterpillar wheel loaders. Manufactured to meet strict OEM quality standards, it provides exceptional durability and operational reliability, unlike a worn bearing that would exhibit excessive play and noise. Operators may notice increased heat, audible grinding, or vibration in the affected component 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 initial symptom of a failing 3648484 bearing is often an increase in operational noise, such as a humming or grinding sound, that may vary with load. If ignored, this can progress to severe vibration, component binding, and potential damage to the surrounding drivetrain or undercarriage parts. This can lead to unexpected equipment downtime.

Installation Tip

Ensure the bearing seat and shaft are perfectly clean and free from any debris or burrs before installing the new bearing. Do not apply heat to the bearing itself; heat the component it fits into if necessary for installation.

Service Note

When replacing the 3648484 bearing, inspect the associated seals, shaft, and housing for any signs of wear, contamination, or damage.
