Description

Volvo Penta 19258 is a genuine OEM ball bearing used in Volvo Penta marine propulsion applications. Volvo Penta’s official parts shop identifies 19258 simply as “ball bearing,” and current catalog references also place it in propulsion-related assemblies rather than as a generic hardware bearing.

Key Features

• Genuine Volvo Penta OEM part number 19258.
• Official Volvo Penta description: ball bearing.
• Current schematic references associate it with AQ165A / Marine Propulsion usage.
• Available fitment references list a 55 mm diameter for this bearing.

Engine Compatibility
Current catalog references connect Volvo Penta 19258 to older Volvo Penta marine propulsion applications, including AQ165A and related propulsion assemblies. Additional aftermarket cataloging also links this number to a wider range of older Volvo Penta marine engine families, but fitment should still be treated as assembly-specific and verified to the exact serial-numbered engine or drive.

Serial Number Fitment Notice
Volvo Penta parts can vary by engine model, drive, and production break. Always confirm part number 19258 against the exact engine or drive serial number before ordering to ensure the correct bearing for the application. Volvo Penta directs owners to identify the exact engine, shield, or drive when locating the correct spare parts.

When This Part Needs Replacement
Replace this bearing when the related assembly shows rough rotation, abnormal play, noise, vibration, overheating, or visible wear during inspection or teardown. Bearings are also commonly renewed during driveline or bearing-housing service when the original part has reached the end of its service life.

Installation Notes
Install only in the correct matched Volvo Penta application using proper bearing handling, support, and press procedures. Inspect the shaft, housing, and adjacent wear components before reassembly, and follow the correct Volvo Penta service documentation for the serial-numbered unit. Volvo Penta’s support portal provides model-specific manuals and service information.

Alternate/Superseded Part Numbers
Current sources reviewed list this bearing under active Volvo Penta number 19258. One aftermarket catalog also associates this part with replacement number 6602924, but serial-number verification remains the safest way to confirm the correct bearing for the exact assembly.

Parts Desk Insight
On older Volvo Penta propulsion packages, bearings can look nearly identical while still differing by housing fit, internal design, or application break. Matching by the exact parts diagram and serial number is the best way to avoid ordering a bearing that is close in size but wrong for the assembly.
