1000/1500-CH Diaphragm Assembly
Slide – 012 O-ring (A) onto the small piston (B). Place the dia-
phragm with hole (C) onto the piston (B). Slide the small washer (D)
onto the piston (B). Attach the thread extension (E) onto the small
piston (B). Torque to 180-220 in.-lbs.

1000/1500-CH Adapter Block Assembly
Insert – 145 O-ring (F) into the adapter block (G). Place the adapter
block (G) between the diaphragm assembly and spring chamber
(H) as shown in Figure 10. Slide the inner tube (I) through the spring
chamber (H). Attach the thread extension (E) to the inner tube
(I) using 1/2-20 SS jam nut (J). Torque the jam nut (J) to 180-220
in.-lbs.

1000/1500-CH Bottom Spacer Assembly
Orient the bottom spacer (K) onto the top body assembly (L). Place
the adapter block assembly onto the bottom spacer (K). Making
sure not to twist the diaphragm (C), thread the small piston (B)
into the outside piston (M) by holding the spring chamber (H) and
rotating the inner tube (I) clockwise. The inner tube (I) is rotated
with the same socket wrench used to hold the jam nut (J) in the
adapter block assembly. When the inner tube (I) cannot be rotated
any more, do not force it; this assembly should only be hand-tight.
