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 Darina® EP 2 grease upon reassembly.
Place (17) “O” ring onto the (43) piston.
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.
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.
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.
Thoroughly grease and install the (16) “O” ring in the (26) air
motor base and bearing assembly.
Place the (25) “U” cup packing, (24) guide washer and (21) re-
taining ring in the (26) air motor base and bearing assembly.
