Disassembly Procedure

2. Remove the gear cover. See: Gear Cover
WARNING: The modulator drive gears are under spring load and will turn during disassembly. After removing the gear cover, exercise
extreme care not to place fingers into the gear set, since fingers can be pinched by the rotating gears.

4. Remove the motor pack from the hydraulic modulator.
Assembly Procedure
1. Position the hydraulic modulator upside down with the gears facing you.
2. Rotate each hydraulic modulator gear counterclockwise until the movement stops. This will position the pistons very close to the top of the
modulator bore, simplifying the brake bleeding procedure.
IMPORTANT:
-
Take care in handling the motor pack. If it is dropped or damaged during handling, the motor pack must be replaced.
-
Align each of the three motor pack pinions with the hydraulic modulator gears.
