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 hydraulic oilʼs temperature 

has dropped.

2.  To prevent a loss of flow of the hydraulic oil, the 

residual pressure in the piping and the internal 

pressure in the hydraulic oil tank should be bled 

out.

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.

•  Damage to each parts, etc.

System”

8.  After installation of the hydraulic unit, be sure 

to pressurize the hydraulic tank. If this operation 

is forgotten, it could cause cavitation of the hy-

draulic pump. Also, it could have a drastic effect 

on the life of the hydraulic pump.
