CLEANING THE STRAINER
Once every three months, remove strainer cap using the correct wrench and turning in
counterclockwise direction. Remove the strainer screen and clean it with compressed air or by
rinsing in solvent.
NOTE:
Always wear protective safety goggles or glasses when using compressed air.
Replace the gasket after cleaning the strainer screen and before reinstalling strainer cap. Be sure
strainer cap is drawn up tight after reinstalling, as a leak will prevent proper operation of pump.
CALIBRATING THE METER
All GASBOY pumps and dispensers are adjusted for accurate measure at the factory. However,
since the conditions of the installation can affect pump accuracy, it is the responsibility of the
installer to check the pump for accuracy and make any needed adjustments. Where required, it is
the owner’s responsibility to report this device to the local Weights and Measures officials for their
inspection before the unit is put into service. Calibration methods are given in gallons. When
calibrating liter pumps, use the same procedure, but convert gallons to liters (1 gallon = 3.78
liters).
The adjustment of measurement is
accomplished by breaking the seal wire and
removing the Seal Pin. This will permit the
Index Disc, to be turned either
counterclockwise (-), decreasing the
measurement, or clockwise (+), increasing the
measurement. A variation of approximately
one cubic inch in measurement is obtained by
turning the Index Disc five holes. After
measurement has been properly adjusted, the
Seal Pin and seal wire should be replaced.
CORRECTING METER DRIVE SHAFT LEAK
If a leak develops around the meter drive shaft, it can be corrected as follows:
1. Remove screws and lockwashers securing gear train assembly and remove gear train
assembly.
2.
Remove following items by lifting from meter cover packing cavity: upper bearing assembly,
washer, seal, o-ring, seal retaining ring, seal, o-ring, and seal retaining ring.
3.

seal, o-ring, and seal retaining ring.
NOTE: Seals are to be formed to meter shaft size by rotating seals on a smooth 3/8" dia.
tapered punch or pencil. Be careful not to damage the seals in the forming
process or when inserting into packing cavity.
4.
Reinstall parts in reverse order of disassembly.
Replacement of meter is recommended if the above procedures do not correct the
problem.
