Pressure reads more than 350 psi / 25 bar
8 Loosen the set screw for the standby pressure
adjustment screw on the rear function pump.
Turn the adjustment screw counterclockwise
(lower pressure) and note if the pressure
drops. If so turn the adjust screw
counterclockwise (higher pressure) until the
pressure reads 350 psi / 25 bar. If the
pressure does not drop, turn the screw slightly
counterclockwise to lower the pressure and
proceed to step 7.
9 Loosen the set screw for the standby pressure
adjustment screw on the mid function pump.
Turn the adjustment screw counterclockwise
until the pressure reads 350 psi / 25 bar.
Tighten the set screw. Proceed to step 8.
10 Turn the adjustment screw on the rear
function pump clockwise until the pressure
reads greater than 350 psi / 25 bar, then turn
the screw counterclockwise until the gauge
reads 350 psi / 25 bar. Tighten the adjustment
screw.
11 Turn the engine off and remove the pressure
gauge.
How to Adjust the Function Pump Pressure Compensator
How to Adjust the Function Pump
Pressure Compensator
Note: Two people will be required to perform this
procedure.
1 Confirm the system relief pressure is set to
specification. Refer to Repair Procedure,
Valve Adjustments - Function Manifold
.
2 Connect a 0 to 5000 psi / 0 to 350 bar
pressure gauge to the test port on the function
manifold
3 Start the engine from the ground controls and
change the rpm to high idle.
4 Push and hold the high speed function enable
button (rabbit symbol). Do not activate any
boom functions.
5 Locate the function enable solenoids below
the function pumps on the engine tray.
Disconnect the wire connector from the inside
solenoid and observe the pressure reading on
the pressure gauge.
Result: The gauge should show 2900 psi /
200 bar on the end pump.
Result: If the gauge does not show 2900 psi /
200 bar, proceed to step 7 to adjust the
function pump pressure compensator.
6 Reconnect the wire connector to the inside
solenoid and disconnect the wire connector
from the outer solenoid.
Result: The gauge should show 2700 psi /
186 bar on the middle pump.
Result: If the gauge does not show 2700 psi /
186 bar, proceed to step 7 to adjust the
function pump pressure compensator.
