VAC-CON pumps are precision machines which embody proven design concepts, exacting manufacturing proce-
dures, and full load testing.
Given proper installation and periodic maintenance, your VAC-CON pump will provide extended, low cost,
dependable service inherent in its quality.

Safety
The truck engine must be shut
OFF
with the key removed from the ignition and the water pump hydrostatic drive
system disengaged before attempting any service on the pumps or pump drive. Air surrounding the unit should be
free of toxic, flammable, or explosive gases.
The tools needed should be planned for in advance (see valve removal instructions) and should be clean and of
adequate size. A torque wrench will be required to tighten connecting rod cap screws.

leave water pump drain valves in the
OPEN
position.
