DISASSEMBLY / ASSEMBLY

21.Assemble one (15) “O” ring and the (16) washer into the

(30)block manifold and against the (13) gland (see figure

5).

22.Assemble four (15) “O” rings, four (18) “O” rings, four (17) spacers and four (19) washers into the (30) block mani- fold (see figure 5). NOTE: Assemble the (19) washers with the i.d. lips toward the (18) “O” ring. Position the (17) spacers so the legs are not aligned with the 3/4 - 14 N.P.T. exhaust ports in the (30) block manifold.

23.Clean the threads in the (20) spool.

24.Apply grease to the exterior of the (20) spool and assem- ble it into the (30) block manifold. Align the slot in the (20) spool with the 3/4 - 14 N.P.T. exhaust port in the side of the (30) block manifold.

25.Assemble the (51) spacer into the (31) cap assembly and assemble the (31) cap assembly to the (30) block mani- fold, securing with four (32) cap screws.

26.Assemble the (12) “U” cup into the groove in the (11) piston, with the lips pointed toward the “boss” side of the piston.

27.Assemble the (10) “O” ring onto the boss portion of the

(11)piston.

28.Clean the threads on the (8) cap screw.

29.Assemble the (8) cap screw and (9) washer thru the (11) piston.

30.Apply Loctite 271 to the threads of the (8) cap screw then thread it into the (20) spool.

31.Insert a 1/4” rod or similar device thru the 3/4 - 14 N.P.T. exhaust port in the side of the (30) block manifold and thru the slot of the (20) spool to prevent it from rotating, then tighten the (8) cap screw. Remove the 1/4” rod.

32.Assemble the (28 and 29) “O” rings into the (30) block manifold.

33.Assemble the (27) block to the (30) block manifold, se- curing with four (26) cap screws (hand tight only).

34.Assemble two (33) “O” rings to grooves in the (34) tube.

35.Assemble the (34) tube into the port provided in the (46) air motor base assembly.

36.Assemble one (33) “O” ring to the counterbore in the bot- tom of the (30) block manifold.

37.Lubricate the bore in the (27) block.

38.Carefully slide the (27 and 30) block assemblies down over the (2) piston assembly and (34) tube and onto the (22) head plate.

39.Assemble six (26) cap screws in the (27 and 30) block assemblies. Tighten the two (26) cap screws in the (27)
