The SEI Upper Drive Shaft Bearing, part number 3854250 / 86748A1 / 8M0103473, is a high-durability marine bearing manufactured to OEM tolerances. Specifically designed for Volvo Penta sterndrive systems, it replaces the original part and is engineered to support rotating shafts in stern drive and drive shaft systems, minimizing axial/radial friction and ensuring vibration-free operation.
Advantages and Features of the Upper Drive Shaft Bearing
- Minimum Friction and Vibration: Ensures shafts rotate on their correct axis, preventing vibration-induced wear and energy loss.
- High Load Capacity: Exhibits high resistance to sudden loads and continuous radial/axial forces encountered in marine conditions.
- Heat-Treated Steel: Manufactured from special marine-grade alloy bearing steel with enhanced corrosion resistance.

Application and Usage
Bearing replacement should be performed when humming from the stern drive area, abnormal operating noise, or shaft play (excessive tolerance) is observed during periodic stern drive maintenance.
Maintenance and Installation Recommendations
Avoid direct hammer blows during bearing installation; instead, use a press or appropriate installation sleeves. Keeping the gearbox oil clean directly extends bearing life.
