Assembly procedure Is the reverse of disassembly with special note to the following:
1. Sight Assembly 38-75, should be carefully reassembled using extreme care not to force parts. The use of Lubriplate on Sight
Balls 600-6 and Spring 38-74 -will aid In keeping parts together during reassembly. When assembly Is complete Sight Bushing
38-29 should be staked to end of 38-16 Windage Screw so that both parts turn as one unit.
2. Valve Spring 38-78A should be assembled with wide end towards 38-13 Valve Washer. Valve Washer 38-12 should be
Inserted with finished side towards center of Stem 38-18. Valve Seat 38-11 should be screwed in until contact Is made with
Valve Washer 38-12. Generally, an additional 1/4 turn will expand Valve Washer 38-12 sufficiently to make contact with Valve
Body 38-9 wall and seal, If proper sealing Is not maintained, additional tightening may be necessary. Excessive tightening will
result in deforming Valve Washer ,38-12, creating leaks and binding on Valve Stem 38-18.
3. Piercing Screen 38-28 should be thoroughly cleaned with proper solvents and forced air before installation.
4. Do not bend Tube 38-48. Bend is preset at factory to prevent binding against hammer. (See Page 23 A-4, Sec. E).

7. After assembly of Valve parts, insert Valve Group 38-73, Cylinder Group 38-68 and Lever Assembly 38-54 as one complete
unit.
