Part Number: 191844 | Brand: Volvo Penta | Type: OEM Hexagon Screw | Supersedes: 3854685 | Sold: Individually
This is the genuine OEM hexagon screw for Volvo Penta DPH-D1 marine propulsion assemblies. Parts references place it at diagram position 5 in the exhaust and cooling water inlet assembly. It is an assembly-specific fastener — not a general-purpose hardware item — and should be sourced as a genuine OEM part to ensure correct thread specification, grade, and length for the application.

When to Replace
Replace this screw when the original is corroded, damaged, rounded, stretched, seized, or removed during service and no longer meets proper reuse standards. It is also good practice to replace fasteners any time the related assembly is fully disassembled and the original hardware shows wear or compromised thread condition.
Installation Notes
- Confirm the correct part number against your drive serial number before installation.
- Clean and inspect the threaded hole and mating surfaces before reassembly.
- Use the correct screw grade and thread engagement for the assembly.
- Torque to the specification in the applicable Volvo Penta service manual.

Parts Desk Insights
Best use case: This is the correct service fastener for technicians reassembling the exhaust and cooling water inlet on a Volvo Penta DPH-D1 drive. It’s most commonly needed when the assembly has been opened for exhaust or cooling system service and the original screw is corroded or damaged.
Common questions: The most frequent issue is customers substituting a generic hex screw of similar thread and size. Volvo Penta fasteners are specified by grade, length, and thread form for the exact assembly — a generic substitute may not provide the correct clamp load or corrosion resistance for a marine environment. Always match by part number from the Volvo Penta parts diagram for your serial-numbered drive, and replace the old screw rather than reusing one that has been seized or corroded.
