Remove the oil tank cap (1) and check if the ATF is at
the upper limit of the filler port (2).
Push the "DN" side of the power tilt switch (3) to
compress each rod fully, and read the pressure gauge
(4) to measure the upper chamber hydraulic pressure.
UPPER CHAMBER HYDRAULIC PRESSURE:
3,923 – 7,355 kPa
(40 – 75 kgf/cm 2 , 569 – 1,067 psi)
If a sharp pressure drop is observed, check the power
tilt motor for a damaged oil seal.
If the hydraulic pressure is lower than the specified
pressure, check for oil leaks.
After checking, push the "UP" side of the power tilt
switch. With each rod extended fully, remove the
special tools (oil pressure gauge and oil pressure
gauge joint A).
• A small amount of oil will flow out when the special
tool is removed. Catch it with a container.
Instal the manual valve (1) to the pump and tighten it to
the specified torque.
TORQUE: 3.4 N·m (0.35 kgf·m, 2.5 lbf·ft)
Install the internal circlip (2).
Recheck the ATF level.
