Serial Number Fitment Notice

Confirm this stud by Volvo Penta engine model, serial number, and the exact parts diagram location before ordering. Volvo Penta uses many similar threaded studs in different lengths and thread configurations, so matching by length alone is not enough. Use 853982 only where the diagram specifically calls for this part number.

When This Part Needs Replacement

Replace this stud if it is corroded, stretched, bent, seized, has damaged threads, or breaks during removal. It should also be replaced during manifold, housing, or engine service if the existing stud no longer provides clean thread engagement or proper clamping support.

Installation Notes

Clean the threaded bore before installation and inspect the mating component, nut, washer, gasket, and mounting surface. Do not force a damaged or corroded stud into the housing. Follow the Volvo Penta service manual for the correct installation procedure and torque specification for the specific engine or drive assembly being serviced.

Alternate/Superseded Part Numbers

• Current Volvo Penta Part Number: 853982

Parts Desk Insight

This stud is used across many Volvo Penta applications, but the installation location matters. A similar-looking stud may have a different length, shoulder, thread engagement, or material requirement. Always confirm the exact diagram callout before replacing manifold or housing hardware, especially on older gasoline and diesel Volvo Penta engines.
