3. DISASSEMBLING & ASSEMBLING OF TRAVEL MOTOR
GENERAL INSTRUCTIONS
Combustibles such as white kerosene are used for washing parts.
These combustibles are easily ignited, and could result in fire or injury.
Be very careful when using.
Internal parts are coated with hydraulic fluid during disassembling and are slippery.
If a part slips out of your hand and fails, it could result in bodily injury or could damage the
park.
Be very careful when handling.
Generally, hydraulic equipment is precisely manufactured and clearances between each parts
are very narrow. Therefore, disassembling and assembling works should be performed on the
clean place where dusts hardly gather. Tools and kerosene to wash parts should also be clean
and handled with great care.
When motor is removed from the host machine, wash around the ports sufficiently and put the
plugs so that no dust and/or water may invade. Take off these plugs just before the piping works
when re-attach it to the host machine.
Bofore disassembling, review the sectional drawing and prepare the required parts, depending on
the purpose and the range of disassembling.
Seals, O-rings, etc., if once disassembled, are not reusable.
There are some parts that should be replaced as a subassembly.
Consult with the parts manual in advance.
The piston can be inserted to whichever cylinder block for the initial assembling.
However, their combination should not be changed if they are once used. To reuse them, put the
matching mark on both pistons and cylinder block before disassembling.
Take great care not to pinch your hand between parts while disassembling nor let fall parts
on your foot while lifting them.
