Installation Procedure


    Object Number: 295301  Size: SH
  1. Position the air temperature actuator, then align the slots in the electric actuator driver to the flats on the shaft.
  2. Align the locating hole to the alignment pin on the HVAC module case.
  3. Slide the actuator driver on to the shaft. The actuator driver should seat completely on to the shaft and the mounting holes should be flush with the mounting bolts on the HVAC case.
  4. 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.

  5. Install the mounting screws to the air temperature actuator.
  6. Tighten
    Tighten the air temperature actuator screws to 1.5 N·m (13 lb in).
