DISASSEMBLING THE GEAR PUMP
ASSEMBLY
Disassembly:
• Power trim and tilt motor
• Tilt cylinder
WARNING
• For disassembly the Power trim and tilt
unit should be fully tilted up (all the tilt
ram should be at full length) to cancel
the internal pressure and prevent the
hydraulic fluid from spurting out.
• After removing the tilt motor or oil res-
ervoir, do not push the tilt ram down.
This may cause hydraulic fluid to spurt
out from the port.
CAUTION:
Do not wipe components of the hydraulic
system with rags, paper, tissues or the like,
as fibers from such materials will cause
malfunctions if they enter the system.
