Testing pressures in the clutch assembly
Connect adaptor 5.9030.517.4 to the hydraulic pressure port of the electrohydraulic control unit (on machines equipped
with electrohydraulic controls) as indicated in fig 14, or to the port of the coupler assembly (machines with mechanical
controls) and fit pressure gauge 5.9030.514.0.
Allow oil to circulate through the directional control valve and read the gauge, which should show 18 bar approx.
For pressure testing procedures and prescribed values, refer to the “electrohydraulic controls” chapter.
