Using the quick connect coupling that comes
attached to the pressure gauge, connect a
pressure gauge to the top of the standard
piping assembly. Refer to
Figure 9
.
NOTE:
The proper gauge to be used
depends
on
the
equilibrium
pressure
determined by the type of grease during
testing. Generally, it is recommended to begin
with the 5000psi maximum gauge when the
theoretical pressure is unknown so as not to
damage smaller range gauges.
12.
Access the Receiver Chamber
(Figure 2, Item
3)
and insert a thermocouple into the grease
sample through the thermocouple ferrule at
the bottom of the grease cylinder.
13.
Connect the Thermocouple port to the Sample
Temperature Display input located in the
Receiver chamber. See
Figures 14 and 15
.
Once this connection is established the
Sample Temperature Display on the Control
Box
will
display
the
grease
sample
temperature.

The grease cylinder loading procedure is now
complete. Before attaching a capillary,
changing the flow of the hydraulic fluid and
starting a test, the sample grease must attain
temperature equilibrium with the test chamber.
The time to attain temperature varies with the
grease being tested, however the user should
expect a wait time of approximately 2 hours
prior to equilibrium and start a test.
5.5 Testing Procedure
1.
Prior to performing the testing procedure,
confirm that the grease sample temperature
has come to equilibrium with the chamber
temperature.
2.
Attach Capillary No. 1
(Figure 1, Item B)
to
the bottom of the grease cylinder via the
receiving chamber
(Figure 2, Item 3)
and
tighten using a wrench provided.
3.
Press the Gear Switch
(Figure 4, Item 15)
to
simulate the 40-tooth gear speed.
4.
With the Grease Cylinder properly connected
to the hydraulic system connection point and a
pressure gauge connected to the grease
cylinder assembly the flowing hydraulic fluid
can be redirected to the grease cylinder to
build pressure for testing.
5.
Open Right-Hand Needle Valve

Item 10)
.
6.
Close Left-Hand Needle Valve.
(Figure 3,
Item 8)
.
7.
Observe the pressure gauge connected to the
grease cylinder. Pressure will begin to
increase until an equilibrium pressure is
obtained. Record the pressure.
