Disassembly (Power Cylinder)

  1. Scribe a line across front and rear housings to aid in reassembly. Remove master cylinder if not done during removal. Remove front housing seal and master cylinder piston push rod. Attach unit to a suitable holding and separating fixture (J-22805 or J-23456). Separate housings using a suitable spanner wrench (J-9504).
    NOTE: On tilt bracket mounting, use spanner wrench with suitable adapter (J-22893).

    Press down and turn counterclockwise.

    CAUTION: Separate slowly, as unit is under internal spring pressure. Ensure no pressure is put on plastic power piston.
  2. Remove power piston return spring (retainer plate may come out with spring). If defective, remove check valve and grommet. Remove front housing seal. If equipped, remove push rod clevis and lock nut, from rear housing. Remove boot, felt silencer, power piston group, and seal from center of rear housing.
