2001 Ford F-350 Super Duty Clutch Master Cylinder Parts Q&A

• Q: How to service and repair the clutch master cylinder and reservoir on 2001 Ford F-350 Super Duty?

  A: The repair and servicing of the clutch master cylinder together with its reservoir requires full removal of the entire clutch hydraulic assembly from the vehicle before installing a new clutch master cylinder assembly. Users must disconnect the clutch hydraulic tube from the dash clip and then support the vehicle before removing the slave cylinder from the transmission through compression and twisting movements to unlock it. The clutch hydraulic tube should be disconnected from its floor pan clip to let the slave cylinder and hydraulic tube drop forward beside the left engine bank before the clutch master cylinder is separated from its clutch pedal and support bracket. Lower the vehicle to access the clutch master cylinder push rod while removing the retaining clips that secure both push rod bushings. The push rod should be separated from the clutch pedal before discarding the bushing unit. You must first remove the switch cover together with the clutch pedal position switch from the clutch master cylinder push rod and disconnect the power distribution box from its bracket for clutch master cylinder access. Follow the procedure to extract the clutch master cylinder from the pedal assembly while angling it at 45 degrees clockwise orientation. Locate the clutch reservoir from its wiring tray position then disconnect the hydraulic tubing between the brake master cylinder assembly and bring the reservoir to a separate location. After cleaning the clutch hydraulic system parts for contaminant prevention the technician must set down a suitable containment container before removing the hydraulic tube. To detach the hydraulic tube from the clutch master cylinder start by driving out the roll pin with a 3/32-inch punch and finally disposing of the pin before tube detachment. Cut the O-ring seal off from the hydraulic tube end before placing a cover on the open tube tip. Install the new push rod to the clutch master cylinder but keep the master cylinder reservoir elevated above its location while filling the assembly with Ford High Performance DOT 3 Motor Vehicle Brake Fluid C6AZ-19542-AB or equivalent that meets Ford specification ESA-M6C25-A. Fill the reservoir twice or thrice to purge all air and then install the reservoir cap and master cylinder port cap. Install the new O-ring seal at the hydraulic tube end before coating it with DOT 3 Brake Fluid and using it to connect the clutch master cylinder. Also secure the hydraulic tube with a new roll pin installed. Position the clutch hydraulic system in the vehicle while bleeding the hydraulic system bench and correctly route the hydraulic tube before attaching the clutch hydraulic reservoir to the wiring tray. The clutch master cylinder requires installation by using counterclockwise torque to twist it 45 degrees until it locks to both the clutch pedal and support bracket while maintaining the O-ring position against the bulkhead. The clutch master cylinder-to-slave cylinder hydraulic tube should run under the brake booster reservoir and the power distribution box needs to be attached to the bracket. Apply the clutch pedal position switch to the clutch master cylinder push rod with its flat side directed towards the clutch master cylinder tab and its wiring connector positioned at 12 o'clock, then fasten it using the switch cover. Secure the new push rod bushing afterward connecting the clutch master cylinder push rod to the clutch pedal followed by vehicle suspension and proper routing of hydraulic tube and slave cylinder to the transmission and finish the installation by compressing and twisting the slave cylinder to secure its placement against the transmission. Lower the vehicle and perform testing for system operation after connecting the clutch hydraulic tube to the floor pan clip and the dash clip and pressing the clutch pedal to push the rod into the clutch master cylinder.
