859902 Shim | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta shim from the Engine group, catalogued at 0.123 inch thick and listed for 9 applications across the TMD, MS, TAMD and MD engine series. It is one of four steps in this run published in inches rather than millimetres, alongside 859916 at 0.109 inch, 859917 at 0.108 inch and 859919 at 0.106 inch. By part number it sits between 859899 at 3.20 mm and 859903 at 3.10 mm. Measure in the same units as the marking before ordering, and take no notice of weight, which does not follow thickness anywhere in this run.

🔌 Function

Adds an exact thickness of steel to the stack so the working clearance can be brought to specification by selection.

⚠️ Common Signs of Failure

• Clearance outside specification at a routine check
• Noise from the assembly the shim sets
• Face worn bright, dished or pitted
• Measured thickness under the published figure
• Marking corroded or rubbed away

🛠️ Service Notes

• Set the micrometer to the same units as the marking — this step is published in inches while most of the run is in millimetres
