Removal and Installation
sorry i misunderstood your question, it does not appear to need any special service tool for the clutchmaster cylinder replacement, according to ford manual.
CAUTION: For vehicles equipped with external clutch slave cylinders (7A508), prior to any vehicle service that requires removal of the clutch slave cylinder (i.e., transmission removal), the master cylinder push rod must be disconnected from the clutch pedal (7519). If not disconnected, permanent damage to the clutch slave cylinder will occur if the clutch pedal is depressed while the clutch slave cylinder is disconnected.
NOTE: When replacing a dry clutch master cylinder (7A543), remove tubing from vehicle and connect to clutch master cylinder. Perform benchbleed procedure in this section.
For installation, follow removal procedures in reverse order. Bleed system as described in Clutch Hydraulic System Bleeding in the Adjustments procedures in this section.
As the clutch disc (7550) wears, the fluid level in the clutch master cylinder reservoir will rise. The proper fluid level is indicated by a step on the clutch master cylinder reservoir. Do not overfill. The fill line step in the clutch master cylinder reservoir is the normal level for a new system. The upper portion of the clutch master cylinder reservoir must accept fluid that is displaced from the clutch slave cylinder as the clutch wears.
