Regal V6-3.8L SC VIN 1 (1998)
Traction Control Module: Service and Repair
Brake Modulator Gear Replacement
REMOVAL PROCEDURE
CAUTION: The modulator drive gears are under spring load and will turn during disassembly. After removing brake modulator drive
gear cover, exercise extreme care not to place fingers into the gear set, since fingers can be pinched by rotating gears.
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. 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.
IMPORTANT: Do not repair damaged motor packs or brake modulators. Other than modulator drive gears replacement, repair of the motor pack
and brake modulator assemblies is not authorized. Do not oil or lubricate the gears on the motor pack.
1. Remove the modulator/master cylinder assembly. Refer to Brake Modulator Replacement.
2. Remove the Torso head screws that attach the gear cover.
3. Remove the four motor pack to modulator Torx head screws.
IMPORTANT: Use care when handling the motor pack. Replace the motor pack if the motor pack is dropped or damaged during handling.
4. Separate the motor pack from the modulator.
5. Remove three modulator drive gears from the modulator drive shaft retaining nuts.
6. Remove the gears from the modulator.
INSTALLATION PROCEDURE
1. Position the modulator drive gears onto the modulator drive shaft.
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. 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.
NOTICE: Refer to Fastener Notice in Service Precautions.
2. Install three gear retaining nuts.
