DISASSEMBLY AND ASSEMBLY
General Cautions
• Always be sure to work on a stable, level sur-
face.
• When disconnecting hydraulic hoses, be sure to
bleed off any residual pressure in the hoses.
• Plug openings which are opened up when piping
is disconnected to prevent dust and mud, etc. from
getting in.
• During assembly, be sure to adjust all the parts
with shims so that there will be no looseness in
the mounts.
• When aligning pin hole positions, absolutely do
not insert a finger in any pin holes.
• When fastening the lock bolt with double nuts,
maintain a clearance between the nuts and the
bushing of 0.5~1.0mm when tightening the dou-
ble nuts.
• When all the hydraulic equipment such as hydrau-
lic cylinders and piping have been removed and
the hydraulic cylinders are being operated for the
first time after reassembly, be sure the bleed the
air out of the hydraulic circuits by the following
procedure.
Air Bleeding Operation
1. Start the engine and let it idle for about 5 min-
utes.
2. With the engine running at slow speed, extend
and retract the cylinders 4 or 5 times.
• Move the piston rods to a position 100 mm
before the end of the stroke, taking care not
to allow any relief whatsoever.
3. Perform the operation in (2) with the engine at
top speed, then with the engine at slow speed,
move the piston rods to the stroke end, allowing
relief.
Removing the Quick-Hitch
• Bring the side of the quick-hitch that comes into
contact with the bucket down and into contact
with the ground.
1. Remove bucket pins (1) and (2) to remove the
quick-hitch (3).
Quik-Hitch: Approx. 81 kg
2. Remove the hydraulic hoses (4) from the bucket
cylinders (5).
3. Suspend the bucket cylinder (5) temporarily,
take out the pin (6) and remove the bucket cyl-
inder.
Bucket Cylinder: Approx. 28 kg
Installing the Quick-Hitch
Follow the procedure used for removal in reverse
order.
