Grand Prix V6-3.8L SC VIN 1 (1997)
Gear Removal
6. Gears from modulator.
Gear Position
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. 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.
INSTALL OR CONNECT
1. Position ABS brake modulator drive gears onto brake modulator drive shaft.
2. Install three gear retaining nuts.
-
Tighten nuts to 8.5 Nm (76 inch lbs.).
3. With either of the brake modulators upside down, and the gears facing you, rotate each ABS brake modulator gear counterclockwise until
movement stops. This procedure will position the pistons on the ABS brake modulator very close to the top of the modulator bore. This will
simplify the brake bleeding procedure.
4. Position the motor pack onto brake modulator, aligning the three motor pack gears with the modulator gears.
Important: Take care in handling the motor pack. If dropped or damaged during handling, the motor pack must be replaced.
5. Four motor pack to brake modulator Torx(R) head screws.
-
Tighten Torx(R) head screws 4.5 Nm (40 inch lbs.).
6. Gear cover onto brake modulator with Torx(R) head screws.
-
Tighten Torx(R) head screws to 4 Nm (35 inch lbs.).
7. Brake Modulator (ABS) and Master Cylinder assembly. Refer to BRAKE MODULATOR (ABS) and MASTER CYLINDER. See: On-Vehicle
