120615 Shim | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta shim in the 0.10 mm thickness, used to set and correct clearance or preload during assembly of D4 and D6 marine diesel engines and DPH sterndrive units. Shims of this type are supplied in several thicknesses, and this item is specifically the 0.10 mm version, so the correct thickness must be selected against the measured clearance. Installing the wrong thickness will leave the assembly out of specification.

🔌 Function

A shim is a precision spacer used to adjust clearance, endplay or preload between mating components to the manufacturer's specification. Thickness is selected during assembly based on measured values, with this item providing a 0.10 mm adjustment increment.

⚠️ Common Signs of Failure

• Measured clearance, endplay or backlash outside the specified tolerance
• Visible wear, scoring or polishing on the shim faces
• Deformation, dishing or cracking from over-compression
• Abnormal noise, knock or vibration from the shimmed assembly
• Premature bearing or gear wear caused by incorrect preload

🛠️ 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
