5. Assemble the packing nut as follows:
a. Component A (ISO) Pump:
• Install spring (25) in the wet-cup (19).
• Install o-rings (24*, 26*) on the piston (28) and
insert the piston in the wet-cup.
• Compress the piston (28) into the wet-cup,
using a 1/2 in. (13 mm) x 2.5 in. (64 mm) bolt
with washers and nut.
• Install the retaining ring (22*) in the groove.
• Remove the bolt, washers, and nut.
• Install the o-ring (27*) on the wet-cup.
• Install the packing wet-cup assembly hand-
tight. Screw the assembly all the way down, so
the external o-ring (27) seats on top of the cyl-
inder (2).
b. Component B (Resin) Pump:
• Install felt washers (21*) into packing nut (19).
• Install the retaining ring (22*).
• Install the packing nut handtight.
NOTE: The groove (H) in the sleeve outer surface must
be toward the bottom.
6. Lubricate the piston u-cup and sleeve top edge.
Push the piston assembly into the top of the sleeve
(4). Drive in with a non-sparking hammer.
7. Lubricate the top 1-2 in. (25-50 mm) of the
displacement rod (1) and outside of the sleeve (4).
Grease the o-rings (3*) and place one in the cylinder
and other on the bottom of the sleeve.
8. Slide the sleeve into the bottom of the cylinder (2).
Drive in with a hammer until the top of the groove
(H) aligns with the bottom of the cylinder (L). Use a
plastic rod to drive the displacement rod until
1/4-3/8 in. (6-10 mm) of its greatest diameter is
visible above the packing nut (19).
