• Middle thickness of the three-shim family
• For 2 XDP drive applications
• Marine Propulsion group
• TH=0.10mm (Volvo assembly listing)

🔌 Function

Takes up a measured amount of axial space in the stack so a bearing preload or gear clearance lands on its specified figure.

⚠️ Common Signs of Failure

• Whine or growl from the drive that varies with throttle
• Endfloat or backlash reading off specification when the stack is checked
• Shim visibly dished or polished on one face
• Fretting marks where the shim met the bearing race
• Setting drifting after the first hours of running

🛠️ Service Notes

• The published weight of 0.041 kg is far heavier than either neighbouring thickness in the same set, so it is no guide at all - order by the 0.10 mm figure
• Measure the stack and select the thickness rather than fitting a shim on assumption
• The alternatives are 3860638 at 0.08 mm and 3860640 at 0.13 mm

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
