1677351 Shim | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta shim is a calibrated valve-clearance shim used in the exhaust-valve clearance adjustment. 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. Calibrated shim thickness: 3.10 mm. In service, it sets exhaust-valve clearance by providing a calibrated 3.10 mm thickness at the designated valve-train position. Selection must be confirmed by OEM part number 1677351, the exact engine/product model, serial number and the installed assembly configuration.

🔌 Function

A shim is a precision-thickness spacer fitted between mating engine components to establish the correct clearance, preload or alignment. Selecting the appropriate thickness brings the assembly within the manufacturer's specified tolerance.

⚠️ Common Signs of Failure

• Measured clearance outside the specified tolerance during assembly or inspection
• Visible wear, scoring or pitting on the shim faces
• Distortion, cracking or deformation from over-tightening or fretting
• Abnormal mechanical noise or knocking traced to excessive component play
• Shim displaced or dropped out of position on disassembly

🛠️ Service Notes

• Shims are supplied in graded thicknesses and exist to bring a setting into specification, so measure with a micrometer and select the thickness the setting procedure for your engine calls for rather than matching one by eye
• Note which shim came from which position on removal and keep them identified — once an assembly has bedded in, shims are not interchangeable between positions
• Check both faces are clean, flat and free of burrs, corrosion and old sealant before fitting; dirt trapped under a shim shifts the setting as surely as the wrong thickness does
• Discard any shim that is dished, cracked, pitted or fretted rather than reusing it, and make sure no old shim has been left behind in the recess
• Recheck the clearance or setting after the assembly is tightened down, because clamping load can change the measurement you took loose
