1675387 Washer | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta washer is a load-distributing retaining washer used in the idler-pulley protecting-cover washer. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it spreads retaining load and maintains the correct cover or idler-pulley mounting stack. Selection must be confirmed by OEM part number 1675387, the exact engine/product model, serial number and the installed assembly configuration.

🔌 Function

A washer distributes the clamping load of a bolt or nut across the mating surface and helps maintain correct joint tension. It also protects the component face from scoring as the fastener is tightened.

⚠️ Common Signs of Failure

• Visible deformation, dishing or cracking of the washer
• Corrosion or pitting that reduces the bearing surface
• Fasteners repeatedly loosening or losing torque at the joint
• Fluid or gas seepage at a sealed bolted joint
• Score marks or indentation on the mating component face

🛠️ Service Notes

• Check you are fitting the same type of washer that came out — plain, hardened, sealing and locking washers are not interchangeable, and the wrong one either fails to seal or fails to hold
• Treat sealing washers on fuel, oil and coolant unions as single-use; they seal by deforming onto the faces, so a used one will not seal reliably a second time
• Clean the seating faces and make sure the washer sits flat and square, fully under the head or nut, before tightening — a washer trapped on a chamfer or edge will crush unevenly
• Tighten the fastener to the figure given in the workshop manual for your engine, and account for every washer on reassembly so none is left loose inside a housing or the engine bay
