ISSUE: Incomplete clutch release and/or hydraulic fluid leaking into the cab from the clutch master cylinder may be caused by the reinforcement plate on the clutch master cylinder separating from the dash panel. The separation of the reinforcement plate reduces the clutch master cylinder pushrod travel. Reinforcement plate separation can also cause deflection of the clutch master cylinder that results in a misalignment of the pushrod to the clutch master cylinder. Misalignment causes the Oring in front of the secondary seal to leak hydraulic fluid.
ACTION: To correct this, install a new service released clutch master cylinder mounting bracket. Refer to the following procedure for service details.
1. With an assistant pushing the clutch pedal down several times, check for separation between the dash panel (cowl) and the clutch master cylinder reinforcement dish.
NOTE: THIS MUST BE DONE FROM UNDER THE HOOD IN THE ENGINE COMPARTMENT.
2. If separation is present, install a new clutch master cylinder mounting bracket, (E8TZ-7K509-A for 1988 model year trucks or E3TZ-7K509-A for 1987 model year trucks). Refer to the following service details:
a. Remove the two (2) clutch master cylinder retaining nuts.
b. Position the clutch master cylinder forward.
c. Repair and seal the dash panel, as required.
d. Install the clutch master cylinder mounting bracket onto the clutch master cylinder mounting studs.
e. Reposition the clutch master cylinder.
f. Reinstall the clutch master cylinder retaining nuts. Torque to 7-11 lb.ft. (9-15 N-m).
