# 184683 Inner Ring | Genuine Volvo Penta Part

🔧 Product Description

  

Genuine Volvo Penta Inner Ring - Part Number: 184683

  

This genuine Volvo Penta inner ring is a hardened bearing inner race manufactured for the matched needle or roller-bearing assembly used in the DuoProp, DPS and XDP lower-unit propeller-shaft bearing race. It is manufactured to the original Volvo Penta dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it forms the replaceable hardened race for the lower-unit propeller-shaft bearing, preserving shaft support and correct bearing geometry. Selection must be confirmed by OEM part number 184683, the exact engine or product model, serial number and installed configuration.
