Maintenance
(Cont.)
Inspect the packing nut daily. If
seepage of paint into the packing
nut and/or movement of the piston
upward is found (while not
spraying), the packing nut should
be tightened enough to stop
leakage only, but not any tighter.
Overtightening will damage the
packings
and reduce the packing
life.
4. Lubricate connecting rod pin every
3 months.
OIL AND LUBRICATION PROCEDURE
Figure 12 shows the necessary steps
involved in proper lubrication.
V-PACKING REPLACEMENT
Refer to Figure 9, 10 and 11 on pages
10 and 11 for corresponding part
illustrations.
V-Packing Replacement Kit Severe Duty
(PN 187-040) contains leather and
plastic packing, Teflon and Viton O-
rings, balls and plastic dual-sided
female adapter and larger male
glands. Gland Kit: PN 187-064.
1. Remove fluid pump as described in
“Fluid Pump Disconnect”
instructions on page 10.
2. Unscrew and remove the inlet valve
per instructions on page 11.
3. Unscrew and remove the packing
nut (187-046). Push the piston rod
down through the packings and
out of the pump. Utilizing packing
removal tool (187-249) the
complete packing set can be
removed quickly and easily.
Another method is to wrap some
masking tape around the bottom of
the piston. Now push the piston
back through the pump and
remove through the top. The
packings and glands will be
removed with the piston rod,
leaving the fluid body empty.
4. Disassemble and clean all parts for
reassembly. Discard old packings.
Save metal upper glands.
Replace metal lower glands
with new metal glands from
Packing Kit. If the old packing
had metal gland for 187-058
discard and replace with plastic
187-058.
5. Remove the outlet seat support,
outlet seat, outlet ball, O-ring and
ball cage as previously described on
page 11.
