BEYERS MODEL 100 PRESSURE
TEST KIT (SE-2239)
The Pressure Test Kit (Figure 12) can be used to
measure intake manifold (boost) pressure, fuel pressure,
air cleaner restriction, exhaust back pressure and
crankcase pressure, however, because of the low
maximum limit of crankcase pressure, the use of this kit
is not recommended. It may also be used to check the
radiator cap and to test the accuracy of the gauges within
Figure 12. Pressure Test Kit
The 0-15 psi gauge may be used to check the radiator
cap. The hand operated pump is usually connected to
the 0-15 psi gauge. By rerouting the tubing under the
panel, it may also be used for testing the accuracy of the
The 0-30 psi gauge may be used to check intake
manifold (boost) pressure and fuel modulator diaphragm
(Aneroid) leakage test. Refer to SLF- 78-19 (ESB-78-10)
when performing leakage test.
The 0-60 inches of water (magnahelic) gauge may be
used to measure air cleaner restriction and exhaust back
pressure. Although crankcase pressure is measured in
inches of water, the low maximum limit prohibits the use
of this 0-60 inches of water.
gauge. The water manometer is recommended for
measuring crankcase pressure
The 0-160 psi gauge is normally used to check fuel
The 0-300 psi gauge is not normally used for any engine
MAINTENANCE AND GAUGE ACCURACY TEST
Remove cover of pressure test kit and inspect
for damage to gauges such as broken cover
glass, bent gauge needles, and for missing
pressure connectors and nylon tubing. Replace
damaged or missing parts so that the kit will
operate when needed.
Remove the screws holding gauge panel to
carrying case and lift panel from carrying case. If
any liquids are found in the tubing behind the
panel, loosen the connections and blow out the
liquids. Tighten all connectors as required and
reassemble gauge panel.
The hand operated pump is directly connected to
0-15 psi gauge when the kit is received. If a
gauge accuracy test is desired, proceed as
PRESSURE KIT (SE-2239) using the Dwyer
Slack Tube® Manometer," in this section.
Connect tubes between the test ports on the panel and
the test points shown in Section 5.
The quick disconnects have shut-off
valves in the panel connectors not in the
plug. DO NOT connect or disconnect
lines while under pressure.
NOTE: When using the inches of water, magnahelic
gauge, be sure to use the proper panel connector.
connector and air cleaner restriction uses the
"Vacuum" connector. In both cases, the opposite
connector MUST be vented to the atmosphere by
installing a quick connective plug in the port.
