1.
Loosely install throat packing (BL) with the open
end facing into the pump.
2.
Install packing nut (BM) hand-tight.
3.
Lubricate the balls (BS, BD) to ensure they do
not stick.
4.
Install outlet ball (BS), outlet ball stop (BG) with
o-rings into rod (BF). Ensure outlet ball stop
o-rings are in the grooves on the outlet ball stop
rod.
5.
Grease the packing on the rod (BF).
6.
Gently slide rod (BF) through throat packing (BL).
7.
Install coupling (BF3), slide coupling cover (BF2)
over coupling, then install clip (BF1) to secure
pump rod (BF) to air motor.
8.
Use a flat-tip screwdriver and a plastic mallet to
tighten packing nut (BM) until it stops.
Note
NOTE:
NOTE:
NOTE: This is not an adjustable packing
but the packing nut (BM) does need to
be tight against the throat packing (BL).
9.
Slide cylinder (BI) over rod (BF) with o-ring (BT)
installed between outlet housing (BK) and
cylinder (BI).
Note
NOTE:
NOTE:
NOTE: If the o-ring (BT) does not stay in
place while assembling the cylinder (BI)
to the housing (BK), the cart may need
to be tipped upright to install properly.
After clamp is installed, tip cart back to
horizontal position to finish assembly.
10. Use cylinder clamp (BJ) to secure cylinder (BI)
to outlet housing (BK).
Note
NOTE:
NOTE:
NOTE: Each clamp has one flat so that
only one wrench is required to tighten
clamp. Align bolt head with flat then
use a wrench on the nut to tighten.
Tighten both sides of the clamp evenly to
approximately 10 ft-lb (14 N•m).
11. Install inlet ball (BD), ball cage spring (BV), and
inlet ball stop (BE) in inlet housing (BC).
12. With inlet ball (BD), ball cage spring (BV), and
inlet ball stop (BE) in place, place o-ring (BT)
between cylinder (BI) and inlet housing (BC)
then use inlet housing clamp (BB) to install inlet
housing (BC) onto cylinder (BI).
