    Important: Be sure all parts are clean and free of lint and dirt. The valvebody should be assembled in a clean area.

  1. Install the valves, new gaskets, and ball check valves according to the figures.
  2. Install the 2 halves of the valvebody and install the 1 bolt holding the 2 halves together (3) .
  3. Important: The dowel bolts must be placed in the holes shown to align the upper valvebody to the lower valvebody.

       • The valvebody-to-case dowel bolts (1)
       • The upper to lower valvebody dowel bolts (2)
       • The bolt holding upper and lower valvebody (3)

  4. Lube the solenoid O-rings.

  5. Object Number: 859193  Size: MF
  6. Install the solenoids with a twisting motion.
  7. 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.

  8. Install the detent arm and bolt.
  9. Tighten
    Tighten the valvebody assembly bolts to 11 N·m (8 lb ft)

    Notice: Over-torqueing bolts can cause valves to bind.

  21. Tighten the solenoid cover bolts using the tightening sequence shown in illustration.
  22. Tighten
    Tighten the valvebody assembly bolts to 11 N·m (8 lb ft).
