2. Set the trigger and spring aside.

4. Pull the trigger valve assembly out of the gun frame, Mine separated and required long nose pliers to pull the second half of the assembly out.
5. Inspect the empty hole for dirt and or debris, clean as needed.
6. Take the new valve assembly and use a light touch of Vaseline on the two rubber \"O\" rings just to help them insert in the frame. Caution do not block the air gaps in the valve system, just a light touch of lube to help assembly.
7. Orient the gray safety lever in the correct position and insert the valve assembly into the gun frame. align the two notches so the spring pins will slide in place.
8. Insert the spring pins Long and Short in the correct holes, tap them in until evenly seated. (same amount showing on both sides)
9. Place the trigger and spring back into position and push the hinge pin in making sure it engages the safety bar (this should not have moved but if it did make sure it is back where it belongs so the hinge pin keeps it in place).
10. Place the retaining rubber washer on the end of the hinge pin and you\'re back in business
