Power Brake Booster: Installation
NOTE:
Internal components of this booster are not serviceable. The housing must not be unstaked and separated. Separating the housing will cause permanent deformation, preventing the booster from holding proper volume.
NOTE:
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
- Attach Power Brake Booster Holder (J 22805-01), or equivalent, to brake booster if not already attached. See Figure. Tighten nuts to 20 ft. lbs. (27 N.m).
- Place the vacuum brake booster (3) on the cowl counterclockwise from the final installation position so that the locking flanges on the vacuum brake booster and on the mounting engage. See Fig 1.
- Turn the vacuum brake booster clockwise with the wrench on the Power Brake Booster Holder (J 22805-01). Do not use a screwdriver in the locking tab in order to install the vacuum brake booster. When the vacuum brake booster is correctly installed, the locking tab (1) slides up the flange and snaps in the locking notch (3). See Fig 2.
- Reverse removal procedure to complete brake booster installation. Use correct tightening torques. See TORQUE SPECIFICATIONS .
NOTE:
Carefully push the pushrod eye through the hole so that you do not damage or dislodge the insulator boot.
NOTE:
Ensure that the locking tab (1) and the flanges are in the fully engaged position.
