PRESSURE
Check:
• Hydraulic pressure
Out of specification → Repair.
Hydraulic pressure
(with the power trim and tilt ram
assemblies fully extended)
9.8 - 11.8 MPa
(100 - 120 kg/cm
(with the power trim and tilt ram
assemblies fully compressed)
5.9 - 8.8 MPa (60 - 90 kg/cm
NOTE:
Before measuring the hydraulic pressure,
bleed the power trim and tilt unit.
Measuring steps
(1) Fully tilt up the power trim and tilt ram
assemblies.
(2) Remove the circlip 1.
(3) Remove the manual valve 2 and
install the up-relief valve attachment
and hydraulic pressure gauge and
tighten them to the specified torque.
