CAT 038-6183 BEARING

CAT 038-6183 is a Caterpillar genuine single-row deep groove ball bearing (pure original factory information, no additional description). It is suitable for water pumps, fans, or drive systems in C6.4/C7/C9 engines and equipment such as the 950H loader and 320D excavator. It is used to withstand radial loads and allows for a small amount of bidirectional axial displacement. It is compatible with the 038-6184 bearing housing, 038-6185 seal ring, and 038-6186 retaining ring assembly, ensuring smooth component operation and sealing protection.

Installation and Maintenance Points
**Before installation, clean the bearing housing and journal, ensuring they are free of oil, rust, and impurities. Inspect the bearing for scratches, deformation, and rust.

Heat the bearing to 50-60℃ using a bearing heater (oil temperature ≤80℃). Install the bearing using a heat-fit method, avoiding hard impacts. Ensure the bearing inner ring fits tightly against the journal without gaps.

Install the 038-6184 bearing housing and tighten it with 098-5511 bolts to a torque of 25-30 N・m. Then assemble the 038-6185 seal ring and 038-6186 retaining ring to prevent dust and grease leakage.

After installation, manually rotate the bearing. There should be no jamming or abnormal noise. The radial/axial clearance should meet the standard (radial clearance 0.015-0.035 mm). Maintenance: Check the bearing condition every 1000 working hours. If abnormal noise, overheating, or clearance >0.05 mm occurs, replace it in time. When replacing, it is recommended to replace the bearing housing, seal ring, and retaining ring at the same time to ensure sealing and installation accuracy.
