Disassembly Steps
1. Inner Rod Assembly
• Press the stopper adapter side by a wrench
and insert a Phillips screwdriver (large) in the
groove of the control cable connector. Then ro-
tate it counterclockwise, loosen it, and remove
it.
Notice:
Be sure to press the stopper adapter side and loosen it
on the control cable connector side. (Press the stopper
adapter side not to rotate the spool valve. Besides, the
three-rotation dump truck is in contrast with this.)
2. Bolt
• Remove three bolts and separate the oil pump
and PTO striking the oil pump by a plastic ham-
mer (or wooden hammer).
3. Spring Pin
• Punch the spring pin in the idle gear shaft.
(After having removed the idle gear shaft,
punch the spring pin from the shaft.)
