cals attached to the pump.
This pump requires little service due to its rugged,
minimum-maintenance design. However, if it be-

parts, follow these instructions which are keyed to
thesectionalview(seeFigure1)andtheaccompa-
nying parts list.
Pump Disassembly
Before attempting to service the pump, close all
valves in the system and remove the suction and
discharge piping. Remove the hardware securing
the pump to its mounting surface, and move the
pump to a clean, well-equipped shop for service.
Loosen the capscrew (4) and remove the lever (7).
Remove the capscrews (6), and pull the lid (10),
wing and shaft assembly (8), and oil seal(9) out of
the housing as a single unit. Remove the housing
gasket set (11) and clean the mating surfaces.
NOTE
Note the location of the words “IN” and “OUT” on
the lid compared to the suction and discharge
ports.Thisisveryimportantforreassembly. Thefill

Lift the suction deck assembly (13) and discharge
deck assembly (3) out of the housing (1). Inspect
the two locating pins (12) for damage. If replace-
ment is required, pull them from the housing.
Pump Reassembly
Clean all component parts with a cloth soaked in
fresh cleaning solvent. Use an approved solvent
when cleaning parts; never use gasoline.
Most cleaning solvents are toxic and
flammable. Use them only in a well ven-
tilated area free from excessive heat,
sparks, and flame. Read and follow all
precautions printed on solvent contain-
ers.
Inspect the parts for wear or damage and replace
as required. If the shaft or wing are damaged, the
complete assembly must be replaced. Individual
parts are not sold separately. The same is true of
thesuctionanddischargedeckassemblies;valves
are not sold separately.
If removed, press new locating pins (12) into the
housing.

housing sothat the valves are directed away from
the center of the pump.

(or hydraulic) press and a suitable sized dowel to
install it in the lid (10) with the lip positioned as
showninFigure1.
