ASSEMBLY

NOTE: All threads are right hand. Inspect and replace old parts with new parts as necessary. Look for deep scratches on metallic sur- faces. Replace all “O” rings upon reassembly. Lubricate all “O” rings and “U” cups with Gadus® S2 U1000 grease upon reassembly.

1.Place (17) “O” ring onto the (43) piston.

2.Place the (14) screw onto the (19) valve rod. The threaded end of the screw should be down, away from the threaded end of the valve rod.

3.While holding the (19) rod assembly below the threads with locking type pliers, clean threads with solvent and apply Loc- tite® 271™ to the threads and attach the (11) extension rod.

4.Place the (19) valve rod into the hole in the end of the (43) piston assembly and screw the (14) screw into the (43) piston assembly.

5.Thoroughly grease and install the (16) “O” ring in the (26) air motor base and bearing assembly.

6.Place the (25) “U” cup packing, (24) guide washer and (21) re- taining ring in the (26) air motor base and bearing assembly.

7.Grease and install (13) “O” ring on the (41) lower gland.

8.Grease the bore in the (35) head assembly and insert (41) lower gland into the bore of the (35) head assembly with a twisting motion.

9.Align the bolt holes in the (41) lower gland and (35) head as- sembly and secure with four (40) screws.

10.Push the (43) piston assembly through the (25) “U” cup pack- ing in the (26) air motor base and bearing assembly, being careful not to damage the “U” cup packing.

11.Thoroughly grease the inside of the (18) cylinder.

12.Apply grease to (17) “O” ring, then insert into the bottom of the (18) cylinder (see figure 5).

13.Push the (43) piston assembly to the top of the cylinder.

14.Thoroughly grease and install the (42 and 16) “O” rings in the

(35)head assembly.

15.Thoroughly grease the two (36) “O” rings and install one on each end of the (44) tube.

16.Press the (44) tube into the counterbored hole in the (26) air motor base and bearing assembly.

17.Push the (11) extension rod through the (42) “O” ring in the base of the (35) head assembly.

18.Align and press the (35) head assembly down until the (18) cylinder and (44) tube are seated in the head assembly.

19.Insert the six (23) bolts down through the holes in the flanges of the (35) head assembly and the air motor base and bearing assembly.

20.Screw the six (22) nuts on the six (23) bolts. Alternately and evenly tighten the nuts.
