4.3 Adjustments
4.3.1 Calibration Fluid Temperature
Adjustment
The CALIBRATION FLUID TEMPERATURE gauge
was calibrated at the factory to indicate the fluid
temperature about one inch upstream of the fuel arm.
This calibration was performed at stabilized
conditions using special fixtures and an electronic
digital thermometer.
Do not change the temperature gauge calibration
without use of a special fixture and procedure.
Bacharach supplies the procedure and special fixture
as part of the CD3 Calibrator Audit Kit (PN 67-7707)
4.3.2 Air Pressure Regulator Adjustment
Required air pressure is set at the factory to produce
the proper clamping force by the air cylinders and the
correct pressure for unlocking the hydraulic cylinder.
If for any reason it is necessary to change this setting:
1. The Primary Air Pressure Regulator should be
set at 90 ± 5 psi, the Secondary Air Pressure
Regulator must be set at 60 +5 -0 psi (4.1 bar).
The air pressure regulators are behind the lower
rear panel (See Section 2.3).
CAUTION
HIGH PRESSURE CAN DAMAGE AIR
REGULATOR. Shop air supply must be
less than 125 psi.
2. To adjust the Primary Air Pressure Regulator, lift
the ring on top of the regulator.
3. Hold the ring up and turn it to adjust the incom-
ing pressure to 90 psi.
4. Push the ring back down to lock the setting.
5. To adjust Secondary Air Pressure Regulator,
loosen locknut and turn adjusting screw clockwise
to increase and counterclockwise to decrease
pressure. Adjust to 60 +5 -0 psi.
6. Retighten the locknut.
