Figure 2-55. Ball Receiver Installation.
b. Separate two hoseline segments (2 and 3) (or hoseline segment and swivel joint).
c. Locate ball receiver (4), consisting of two 8 X 6 inch reducers (5 and 6). One reducer (6) has been
modified to prevent displacement ball from being ejected from ball receiver (4).
d. Connect 6 inch end of unmodified reducer (5) to downline end of first hoseline segment (2) using
grooved-end pipe quick disconnect coupling clamp (1) (para 2.3.3.2).
e. Locate 8 inch snaplock coupling (7). Open coupling.
f. Fit snaplock coupling halves (7) over joined ends of reducers (5 and 6). Close coupling halves (7)
over reducer (5 and 6) ends. Lock snap lock coupling halves (7).
g. Connect nipple (Figure 2-56, 1) to upline end of first hoseline segment (2) using grooved-end pipe
quick disconnect coupling clamp (3) (para 2.3.3.2).
h. Place displacement ball (4) inside nipple (1).
i. Locate pneumatic coupler (5) and modified end cap (6) (with tapped hole). Attach pneumatic coupler
(5) to end cap (6).
j. Connect end cap (6) with pneumatic coupler (5) to end of nipple (1). Use grooved-end pipe quick
disconnect coupling clamp (7) (para 2.3.3.2) from displacement and evacuation kit.
k. Locate pneumatic coupler (8). Screw pneumatic coupler (8) into air compressor line (9).
