2. Torx head screws attaching gear cover.
3. Four motor pack to hydraulic modulator Torx head screws.
IMPORTANT: Take care in handling the motor pack. If dropped or damaged in the handling, the motor pack must be replaced.
4. Separate motor pack from hydraulic modulator.
NOTICE: Do not allow gear to turn while removing the retaining nut, since the modulator piston can hit the top of the modulator bore, damaging the
piston. Turn the modulator gear to position the piston in the center of its travel. Place a screwdriver through the holes in the gears (not between the gears)
into the recessed hole in the modulator base. This will prevent the gear from turning, aiding in gear removal.
5. Three modulator drive gear to modulator drive shaft retaining nuts.
6. Gears from modulator.

NOTICE: Do not allow gear to turn while tightening the retaining nut, since the modulator piston can bottom out in the modulator bore damaging the
piston. Turn the modulator gear to position the piston in the center of its travel.
1. Place a screwdriver through the holes in the gears (not between the gears) into the recessed hole in the modulator base. This will prevent the gear
from turning, aiding in gear installation.

CAUTION: To help avoid personal injury, due to a retained load on the ABS hydraulic modulator, the gear tension relief function of the Tech
1 must be performed prior to removal of the ABS hydraulic modulator/master cylinder assembly. Refer to "Gear Tension Relief Sequence".
NOTICE: Complete overhaul of the hydraulic modulator/master cylinder assembly is not authorized, only the following steps. These steps will break the
unit down into major components for replacement purposes.
