Installation Procedure

    Object Number: 229722 Size: SH

    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.

  1. Install the lower condenser brace to the condenser. Secure the brace with the following components:
    2. • The bolt
    • The washers
    • The nut

    Tighten
    Tighten the lower condenser brace nut to 70 N·m (51 ft lb).

  2. Install the upper condenser brace to the condenser. Secure the brace with the following components:
    3. • The bolt
    • The washers
    • The bracket
    • The nut

    Tighten
    Tighten the upper condenser brace nut to 70 N·m (51 ft lb).

  3. Install the condenser insulator to the frame rail. Secure the insulator with a washer and a nut.

    4. Tighten
    Tighten the condenser insulator nut to 35 N·m (26 ft lb).


    Object Number: 229717 Size: SH
  4. Install the condenser to the frame rail. Secure the condenser with the following components:
    5. • Two condenser mounting bracket insulators
