### Installation Procedure

1. Install the 9 balls into the upper valve body (2).

• | Seven of the check balls have a thickness of 5.50 mm (0.217 in) (1).

• | Two of the check balls have a thickness of 6.40 mm (0.252 in) (3).

2. Install the following onto the lower valve body (3) and secure with two screws (1):

• | The spacer plate (2)

• | Two new gaskets

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.

3. Install the following components onto the lower valve body (3). Secure the components with the two bolts (2):

• | The new lower valve body cover gasket

• | The lower valve body cover (1)

Tighten
Tighten the two lower-to-upper valve body bolts to 6 N·m (53 lb in).

4. Install the lower valve body (2) with the spacer plate and the gasket onto the upper valve body (3).
5. Secure the lower valve body to the upper valve body (1) with the 19 bolts.

Tighten

• | Tighten the 50 mm (1.97 in) lower-to-upper valve body bolts to 6 N·m (53 lb in).
