STEP 98

Shut off the engine. Remove the pressure gauge tee adapter (1) from the hydraulic solenoid (2). Install a cap in the hydraulic solenoid and a plug in the tee adapter.

STEP 97

Start the engine and run at 1000 RPM. Hold the joystick in the position of the function being tested. The pressure gauge should read 350 psi (24 bar).

If the pressure is 400-425 psi (27-29 bar), repair or replace the hydraulic solenoid.

If the pressure is less than 400-425 psi (27-29 bar) proceed to the next step.

Shut off the engine. Remove the pressure gauge from the hydraulic solenoid supply hose (1) and install the supply hose on the solenoid.

STEP 99

Remove the hose from port PB on the flow divider. Install a 1000 psi (69 bar) pressure gauge on port PB and a plug in the hose end.

Start the engine and run at 1000 RPM. the pressure gauge should read 400-425 psi (27-29 bar), repair or replace the park brake cylinder.
