Professional Installation Notes
Cleanliness is Priority: Before pressing the new ring onto the hub, ensure the mounting surface is free of rust, grease, and debris. Even a 0.5mm misalignment can cause an "ABS Sensor Fault" code.
Heat-Shrink Fit: We recommend a gentle, even heating of the ring (using an induction heater or controlled heat source) to allow it to slide onto the hub without excessive force.
Gap Verification: Once installed, use a feeler gauge to check the air gap between the ABS sensor tip and the ring gear teeth. It must fall within the manufacturer's specified range (typically 0.1mm - 1.0mm).
Avoid Hammering: Never strike the ring teeth directly with a metal hammer. Use a specialized press tool or a soft-faced mallet with a block to prevent deforming the teeth.
