Repair of the modulator is not authorized. Replace the modulator as an assembly.

INSTALLATION PROCEDURE





1. With the modulator positioned upside down, and the gears facing you, rotate each modulator gear clockwise until movement stops.
^ This procedure will cause the following conditions:
- The pistons are positioned very close to the bottom of the modulator bore.
- The brake bleeding procedure is simplified.

2. Install the motor pack (1) onto the modulator (6).
3. Install the gear cover (3) to the modulator/motor pack assembly.
