Fitment Notice
Confirm fitment by Volvo Penta drive model, serial number, and the correct lower gear unit parts diagram. This inner ring should be matched by diagram location and part number, as similar lower-unit rings, bearing races, sleeves, and spacer components may look alike but may not interchange between DPH, DPR, and DPI gearcase versions.
When This Part Needs Replacement
Replace this inner ring if it is scored, pitted, worn, corroded, heat-marked, cracked, or damaged during disassembly. It should also be replaced when required during roller bearing, propeller shaft, gearcase, or lower-unit overhaul work. Reusing a worn internal ring can affect bearing support and gearcase service life.
Installation Notes
Inspect the surrounding roller bearing, shaft surface, gearcase bore, seals, spacers, and related lower-unit hardware while the assembly is apart. Internal gearcase components require clean handling and correct seating depth. Follow the Volvo Penta service manual for the proper removal, installation, and inspection procedure for the specific drive model.

Parts Desk Insight
Lower gear unit components should be matched from the exact Volvo Penta exploded diagram, not by appearance. A small internal ring can be critical to bearing support and shaft alignment, and the correct part depends on the drive family, gearcase version, and diagram position.
