🔌 Function

Sets and adjusts the running clearance or preload in a gear or bearing stack by taking up the gap in fine steps.

• Gear or bearing preload out of specification on assembly
• Whine or rumble from an incorrectly shimmed stack
• Shim found dished, notched or spun in service
• Fretting marks on the shim faces

🛠️ Service Notes

• The thinner 0.16 mm shim 3875230 is published heavier than this one, so ignore weight entirely and order by thickness
• The set runs 0.10 mm (3875229), 0.16 mm (3875230), 0.25 mm (3875231) and 0.40 mm (3875232)
• Measure and shim to the specified clearance rather than reusing the old thickness
