GENERAL
CAUTIONS DURING DISASSEMBLY AND
ASSEMBLY
1. Clean the machine before disassembly opera-
tion.
2. Before disassembly, check the machine condi-
tions and record them.
• Model, Machine Serial Number, Hourmeter
• Reason for Repairs, Repair History
• Dirtiness of Filters
• Fuel and Oil Conditions
• Damage to each parts, etc.
3. To make reassembly operations easy, make
matching marks at the necessary points.
4. Clean all disassembled parts and new parts, then
arrange them in the proper sequence.
5. Be sure to replace all seals and cotter pins, etc.,
with new parts.
6. Keep parts which should not come in contact
with oil and water separate from parts with oil
on them.
• Electrical Parts, Rubber, V-Belts, etc.
7. When installing bearings, bushings and oil seals,
as a rule, use a press. When a hammer, etc., is
used, it leaves bruises.
8. Wipe all joining surfaces clean so that there is
no dirt or dust adhering to them.
9. Wrap seal tape from the front end, Wrapping it
tight and leaving 1 or 2 threads bare, Overlap the
tape by about 10 mm.

10. When fitting the snap rings, the bigger, rounder
side of their circumferences should face the
mating surfaces.
CAUTIONS DURING REMOVAL AND INSTALLA-
TION OF THE HYDRAULIC UNITS
1. Make sure that the temperature of the hydraulic
oil has dropped.
2. To prevent a loss of flow of the hydraulic oil,
the residual pressure in the piping and the in-
ternal pressure in the hydraulic tank should be
released.
3. Be sure to install caps or plugs on all openings
in the hydraulic unit to prevent dirt from getting
into the unit through the openings.

4. It is easy to mistake hydraulic oil adhering to the
hydraulic unit for an oil leak, so wipe the unit
off thoroughly.
5. Be sure that no damage is done to the plating on
the rod in the hydraulic cylinder.
6. As a rule, removal and installation of the hy-
draulic cylinder should be done with the rod
fully retracted.
7. Be sure to bleed the air after replacing the hy-
draulic oil or removing any of the hydraulic
devices.
