1. Install the control valve body to spacer plate gasket (22) onto the spacer plate (23).
2. Install the control valve body assembly (18) onto the gasket (22).
3. Inspect the TFP switch assembly (13) in order to verify the condition and correct location of the seven pressure switch O-rings.
4. If necessary replace the pressure switch O-rings.
5. Install the TFP switch assembly (13) onto the control valve body assembly.

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.

7. Hand start the bolts.

Tighten
Tighten the bolts to 14 N·m (124 lb in).
