2-11. ASSEMBLY AND PREPARATION FOR USE - cont.
(6)
Position one half of coupling clamp (4) over coupling gasket (3) and into grooves of both pipe couplings
(1 and 2).
(7)
Close other half of coupling clamp (4) over coupling gasket (3) while alining clamp with grooves of both
pipe couplings (1 and 2) Hold clamp in place.
(8)
Position assembly tool (5) on coupling clamp (4) as shown.
(9)
Push handle of assembly tool (5) toward coupling clamp (4). As clamp is squeezed together, make
sure coupling gasket is not pinched between clamp and pipe couplings (1 and 2). Assembly tool handle
will lock in closed position when clamp is correctly seated in grooves of pipe couplings.
NOTE
Locking pin must be installed with splines (ridges) pointing out from
coupling clamp.
(10)
Using a hammer, drive locking pin (6) through locking pin holes in both halves of coupling clamp (4)
Make sure locking pin is sticking through both halves of clamp.
(11)
Pull handle of assembly tool (5) away from coupling clamp (4) and remove tool.
Removal Refer to figure 2-14.
(12)
Position assembly tool (5) on coupling clamp (4) and push tool handle toward coupling clamp (5).
WARNING
To prevent injury to personnel and damage to the equipment, all water
pumps must be shutdown, water pressure relieved from discharge hoses
and appropriate valves closed before removing coupling clamps.
(13)
Using a punch and hammer, drive out locking pin (6) from coupling clamp (4).
(14)
Pull handle of assembly tool (5) away from coupling clamp (4) and remove tool.
(15)
Open and remove coupling clamp (4) from pipe coupling (1 and 2).
(16)
Separate pipe couplings (1 and 2) and remove coupling gasket (3).
(17)
Install protective covers over over ends of hoses and components.
