Installation Notes

Use the tightening sequence and torque specification for the exact assembly being serviced. A single universal torque value should not be assumed because this screw is used in several different locations. Inspect the mating component and surrounding hardware, and make sure the flange seats fully against a clean mounting surface.

Parts Desk Insights

Best use case: Replacing a damaged or service-required 975101 fastener in a confirmed Volvo Penta parts diagram.

Most common mistake: Ordering by M10 40 mm dimensions alone. Volvo Penta uses visually similar fasteners, so match part number 975101 directly.

Sizing and fitment: Confirm the engine model, assembly, and diagram position before ordering. For D3 seawater-pump applications, also verify the required quantity shown for your exact engine.
