DISASSEMBLY AND ASSEMBLY
Special Tools
See the table of special tools at the back of this sec-
tion for the jigs and tools used for disassembly and
assembly.
General Cautions
• Carry out disassembly and assembly in a clean
place and place the disassembled parts in a place
where they will be kept clean at all times.
• Before disassembly, clean the outside surface of
the cylinder thoroughly.
• In the disassembly and assembly operations, be
careful not to scratch any part. Take particular
caution with the sliding surfaces of parts.
• Clean all disassembled parts thoroughly with
cleaning oil.
• Replace all seals with new parts.
• Apply a thin coating of hydraulic oil to seals be-
fore fitting them in place.
• After fitting, make sure the O-rings are not twist-
ed.
• Apply clean hydraulic oil to each sliding portion
before assembling them.
In this manual, the procedure for the arm cylinder
is described. When necessary, the points which are
different in other cylinders are mentioned.
Disassembly
Cylinder Assembly
1. Fasten the clevis of the tube in a vice and place
the other end on a support black made of wood
to fasten the cylinder in a horizontal condition.
2. Drain out hydraulic oil remaining in the cylin-
der.
• Move the piston rod gently to prevent the hy-
draulic oil from spraying out and scattering
all over.
3. Free the locked portion of the rod cover.
• Since the lock is integrated with the cylinder
tube, be careful not to bend it or to scratch it
when the lock is being freed.
