859908 Shim | Genuine Volvo Penta Part

🔧 Product Description

It follows 859907 at 3.00 mm, and the next step listed here is 859910 at 2.92 mm. Order on the measured thickness alone — across this whole run the published weights bear no relation to the step.

🔌 Function

Sets a clearance to specification by adding a graded, exact thickness of steel to the assembly.

⚠️ Common Signs of Failure

• Clearance out of specification when checked cold
• Noise from the assembly that alters with engine temperature
• Face of the shim worn bright or unevenly dished
• Measured thickness below the marked figure
• Marking no longer readable

🛠️ Service Notes

• Clean the shim seat thoroughly — grit trapped underneath reads as extra thickness and throws the setting out
