1547977 Shim | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta shim is a selective-thickness valve-clearance adjustment component used in the exhaust-valve clearance adjustment. It is manufactured to the original Volvo Penta dimensions and interface requirements so the adjusted valve clearance can be set to the measured workshop specification. Precision adjustment shim, 2.50 mm thickness; commonly supplied within shim assortment 85111158. In service, it sets the exhaust-valve clearance by providing the selected calibrated thickness between the valve-train components. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1547977 against the installed assembly before ordering.

🔌 Function

A shim is a precision-thickness spacer used to establish or adjust clearance, preload or alignment between two mating engine components. The 2.50 mm thickness is selected during assembly to bring the measured clearance within the specified tolerance.

⚠️ Common Signs of Failure

• Measured clearance or endplay falls outside the specified tolerance during assembly checks
• Visible wear, scoring or pitting on the shim faces
• Deformation, distortion or cracking from over-compression
• Unusual mechanical noise or knocking traced to excessive play in the shimmed joint
• Fretting or discolouration indicating the shim has been moving in service

🛠️ 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
