3. SHIFT CIRCUIT SYSTEM PRESSURE-SET @ 2000 PSI/140 Bar
SHIFT RELIEF PRESSURE- 2300 PSI/160 BAR
The S-Tube Shift Circuit manifold is located on the backside of the tank. It contains the relief
and unloader valve. These cartridge valves are used to protect and limit the pressure being
applied to the accumulator and are used to adjust and set the
SHIFT system pressure. To
check and adjust the pressure the following is offered:
A. CHECKING THE PRESSURE
•
Start engine and adjust THROTTLE to maximum RPM.
•
Turn VOLUME control so that it is partially open, #3 position.
•
Loosen locknut on the unload cartridge valve.
•
Using an allen wrench, turn set screw all the way IN .
•
Monitor the accumulator pressure gauge. Gauge should read 2400 PSI. This
indicates the RELIEF VALVE setting. If gauge reads otherwise, then an adjustment is
necessary.
