PISTON SYSTEM
Disassembly
Thoroughly clean the unit before disassembling.
Scrub all outside surfaces with a stiff brush and
hot, soapy water to prevent surface dirt from con-
taminating internal parts.
Always use a lint free shop cloth when handling
power trim/tilt components.
If painting the unit is required, paint it after it is
completely assembled. Painting of individual com-
ponents may cause flakes of paint to enter the
hydraulic passages during assembly. Tape the
trim/tilt piston rods before painting.
IMPORTANT: Before removing manual release
valve, relieve pressure by fully extending cylinder.
Screw the manual release valve in. Remove the
retaining ring using a small pick or screwdriver.
Discard the retaining ring.
Slowly remove the manual release valve. There
may be pressure behind the valve—wear safety
glasses.
Inspect the manual release valve. Discard the
O-rings on the housing.
Remove the four large motor flange retaining
screws. Remove the motor and discard O-ring,
screws, and washers.
WARNING
There may be high pressure behind some
power trim valves. To avoid injury when
removing manual release valve, be sure to
cover valve with a shop cloth until the
pressure is released. Wear safety glasses.
