Installation Procedure


    Object Number: 43535  Size: SH
  1. Install the APP assembly to the steering column support bracket.
  2. Notice: 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.

    Important: Always use a torque wrench in order to obtain the proper torque.

  3. Install the accelerator pedal mounting bolts.
  4. Tighten
    Tighten the accelerator pedal mounting bolts to 20 N·m (15 lb ft).
