⚙️ Key Features

• 2.27 g
• One of a graded run of shims
• No published thickness
• Order by part number

🔌 Function

Sets a measured clearance or preload in the assembly, the thickness of the shim deciding where the mating component ends up sitting.

⚠️ Common Signs of Failure

• Clearance or preload that will not come to specification on setup
• Whine or rumble that changes with load
• Shim dished, bruised or burred at the edges
• Bright fretting marks on the seating face

🛠️ Service Notes

• Weight has proved an unreliable guide across graded shim runs, so measure the shim you remove and order the matching number
• Renew any shim that has dished or picked up fretting damage rather than refitting it

📦 Condition

• Supplied in original or equivalent packaging
