20841078 manual mirror – Description

20841078 manual mirror is a right-side, manual-adjust exterior mirror unit designed to fit trucks compatible with VOLVO when matched by OE reference and mounting configuration. OE references for identification include 20841078 and 20589819. Packing weight is 1.00 kg and packing is 1 pc per box. Fitment should be confirmed by OE reference and mounting configuration before ordering.

In daily operation, a worn mirror unit can introduce vibration, blurred rear view, and unstable positioning on rough roads. This manual mirror supports stable seating when the bracket faces, fixing points, and mirror head outline match the removed unit. Confirm the “Right” position on the vehicle and verify manual adjust movement before final tightening to prevent side or configuration mix-ups.

For fleet purchasing, 20841078 manual mirror can be managed as a service item for platforms commonly used in regional and long-haul routes. Typical listings cover FH (EU, 2005) and FM (EU, 2005) trucks compatible with VOLVO; always compare plug style, arm geometry, and mounting hole spacing. Record 20589819 as a cross reference in your ERP notes to reduce picking errors.

After installation, check for flush seating, stable adjustment, and no rattles during a short road test to confirm correct fit. A correct match should hold firmly at the retention points and remain steady under vibration typical of heavy-duty routes, supporting consistent visibility performance during day-to-day operation.
