1674454 Spacer Plate | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta spacer plate is a machined spacing and alignment component used in the cooling-system fan/radiator spacer plate. 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 sets the specified spacing and alignment within the engine cooling package. Selection must be confirmed by OEM part number 1674454, the exact engine/product model, serial number and the installed assembly configuration.

🔌 Function

The spacer plate maintains a fixed, correct gap between two mated components so that fasteners clamp at the designed depth and mating faces sit in proper alignment. Correct spacing keeps loads distributed evenly and prevents adjacent parts from bottoming out or shifting in service.

⚠️ Common Signs of Failure

• Visible deformation, dishing or crushing of the plate from over-torqued fasteners
• Corrosion, pitting or scaling that reduces effective thickness
• Fasteners that will no longer hold torque, or repeated loosening at the joint
• Misalignment, rubbing or uneven wear on the components the spacer separates
• Cracking or edge damage found during disassembly or inspection

🛠️ Service Notes

• Fit a spacer of the same thickness and type as the one removed — a spacer sets a clearance or an alignment, so substituting one is a change of setting, not a like-for-like repair
• Clean and inspect both faces for burrs, ridges, fretting and distortion, and dress off high spots so the plate seats fully over its whole face
• Keep the original stacking order and orientation where more than one plate or shim is fitted, and note which way round the plate came off
• Renew the gaskets, seals or sealant either side if the joint uses them, and tighten the fasteners evenly to the figures in the workshop manual for your engine
• Where the manual gives a clearance, endfloat or preload to be checked after assembly, measure it rather than assuming the plate has restored it
