1. Install the checkballs (2-6, 8, 12) in the valve body and retain checkballs with J 36850 or an equivalent.
2. Install the valve body over the J 25025-5 Guide Pins, and connect the manual valve link to the manual valve.
3. Install two bolts to hold the valve body in place.
4. Remove the J 25025-5 .

• | Damage

• | Debris

• | Damaged or missing O-rings

• | Cracked connector

• | Loose pins

8. Install the TFP manual valve position switch (69) and bolts (62, 70).

Important: You must tighten certain bolts in a spiral pattern as indicated by the arrows. If you tighten these bolts at random you may distort valve bores. This will inhibit valve operation.

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.

Important: Tighten certain bolts in a spiral pattern as indicated by the arrows. If you tighten these bolts at random you may distort valve bores. This will inhibit valve operation.

12. Tighten the bolts in the order shown.
