1. ABS sensor; 2. Shim; 3. Pulser ring; 4. Fixing
2. Rotate the wheel and repeat the measurement in several places to ensure the pulser ring is not distorted or bent. Renew a damaged pulser ring.
3. Adjust the air gap using the correct shims to achieve an air gap between 0.1 mm to 1.5 mm.
Note:
- Shims are available in the following sizes, 0.8 mm and 1.6 mm.
- Do not install more than two shims. If the required air gap cannot be acheived using two shims, investigate and rectify the cause before proceding.
4. If necessary, remove the wheel speed sensor, fit the correct thickness shim(s) and refit the wheel speed sensor.
5. If removed, install a new fixing and tighten to 9 Nm.
6. Repeat the air gap measurement. Re-adjust as necessary.
