12.0 Technical Information – [cont'd]
12.2 Oil Pressure Check
IMPORTANT
Unsatisfactory performance and/or equipment
damage may result if operated below or above the
accepted specifications. The Skid-Pac is designed
to provide optimum performance with reliable
service at the oil flow and pressure specified in
Technical Data Table.
Measure oil pressure whenever any the following
conditions occur

When first installed on a carrier

When repairs or modifications are made to the
machine’s hydraulic circuit.

When the machine operates other hydraulic work
tools.

When the Skid-Pac is removed from one machine
and attached to a different machine.

Check the pressure every 250 operating hours is
recommended.
12.3 How to Measure the Oil Pressure
CAUTION
Only qualified personnel, having knowledge of the
machine’s systems, proper test equipment and tools
shall attempt testing and adjustments.
WARNING
Prevent accidental start. Engage
interlock, shut off engine and apply
parking brake. Follow all safety and
operating instructions provided by the
carrier manufacturer.
Certain tests, such as measuring the oil pressure,
can only be done while the Skid-Pac is operating.

Lower the Skid-Pac to the ground and stop the
carrier engine.

Relieve hydraulic pressure in attachment circuit.

Connect a pressure gauge [0-5000 PSI] to the
supply hose at the [IN] side of the Skid-Pac.

Use the form provided in Section 12.1 to record
your results.

Start the carrier. Use the controls to align the
Skid-Pac against the ground.

Adjust the engine's rpm to the normal operating
speed and set operating mode to "work tool".

The test can begin when the normal operating
temperature is reached.

Start the Skid-Pac and record the pressure
reading. It's normal for the pressure reading to
increase and decrease as the carrier applies
varying amounts of down pressure.

Compare your results with the values listed in the
General Specifications Table.

When finished with the pressure-measuring test,
lower the Skid-Pac safely on the ground and stop
the engine. Relieve hydraulic pressure in
attachment circuit.
Remove test gauge.
12.4 Definition of Hydraulic Terms
For the purposes of this manual, the following terms
are defined as:
Range – A range is represented by two values 'V1 –
V2' and generally means the lowest-to-highest limit of
a device that will allow it to adequately respond. The
term “minimum flow” describes the least amount
required that permits continuous operation that is
both satisfactory and efficient.
Hydraulic Flow – A measure of the volume of oil
(values given in GPM / LPM) necessary for the safe
and efficient operation of the Allied work tool.
The motor is coupled to the eccentric mass. The
rotation speed of the motor must be kept inside a
narrow flow range. Too little flow results in under-
speeding and unsatisfactory performance. Excessive
flow (above the accepted flow rate) does not improve
compactor performance. Too much flow not only
results in overheating the oil, but will also cause over-
speeding the motor which adds significantly higher
loads that will contribute to early bearing failure.
IMPORTANT
Never use a relief valve as a means to reduce the
hydraulic oil flow to the Skid-Pac. Oil by-passed
over the relief valve will cause significant heat
generation.
