Important: Torque sequence and specification is very
important to valve body operation. If bolts are torqued at random, valve bores may
become distorted and inhibit valve operation. DO NOT use air powered tools when assembling
the valve bodies.
Verify that all parts are clean and dry before assembly.
- Install the separator plate and new gasket to the lower valve body, temporarily
install the two bolts.
Important: Use caution when assembling the upper and

- Install the new upper valve body gasket to lower valve assembly.
- While holding the upper valve body gasket and lower
valve body (1) together, install the assembly to the rear upper valve body
assembly (2).
- Install the three bolts to the lower valve body.
- Turn the lower valve body assembly over and install the four bolts to
the upper valve body side.
- Remove the two bolts temporarily installed in step 1.
- Install the lower valve body assembly to the front upper valve body.
- Install the three bolts to the lower valve body side.
- Turn the valve body assembly over and install the five
bolts to the front upper valve body.
