Marking the ABS sensor ring
- Take load off front wheel and lift clear of ground.
- Remove clamping screw from left fork tube. Secure dial gauge holder, BMW No. 002500, with dial gauge, BMW No. 00 2 510, and measuring shoe, BMW No. 34 2 510, to fork slider tube.
- Zero the dial gauge.
- Measure axial runout round the entire circumference of the sensor ring.
Caution: If replacement parts are fitted, the sensor ring must be re-marked; remove the old mark.
- With a paint pencil, make a permanent mark at the point on the ABS sensor ring at the greatest distance from the ABS sensor.
- Remove dial gauge holder, BMW No. 00 2 500, with dial gauge, BMW No. 00 2 510, from fork slider tube.
- Tighten the clamping screw in the fork tube.
- Check/adjust ABS sensor gap.
