⚠️ Common Signs of Failure

• Measured clearance outside specification on rebuild

• Fretting or bright wear rings on either face

🛠️ Service Notes

• Published weights in this series jump around by a factor of a hundred and do not follow thickness, so order by the 0.13 mm figure and disregard weight
• Check the stack with a dial gauge and select the thickness to suit rather than reusing what came out
• Thinner steps are 3860639 at 0.10 mm and 3860638 at 0.08 mm
