1547983 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, 2.80 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 1547983 against the installed assembly before ordering.

🔌 Function

The shim acts as a precision spacer, allowing a clearance, height or preload to be adjusted to specification during assembly by fitting the correct thickness. Selecting the right shim keeps mating components correctly positioned and loaded in service.

⚠️ Common Signs of Failure

• Measured clearance or preload outside the specified tolerance at inspection
• Visible wear, scoring or polishing on the shim faces
• Distortion, dishing or cracking from fatigue or overload
• Increased mechanical noise, tapping or knocking from the affected assembly
• Accelerated wear on adjacent components caused by an incorrect shim thickness

🛠️ 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
