🔌 Function

Shims the assembly to its specified clearance or preload during setting up.

⚠️ Common Signs of Failure

• Clearance out of specification, giving noise or roughness
• Play or, if too thick, binding and localised heat
• Fretting or dishing on the washer faces
• Uneven bearing wear when the assembly is opened up

🛠️ Service Notes

• Set the shim by measurement during assembly, not by copying the washer that came out
• Weight does not separate this family - 3840477 weighs the same, so order by the 2.90 mm thickness
• Inspect the mating faces for wear that would falsify your measurement
