DISASSEMBLY AND ASSEMBLY
General Cautions
• When disconnecting hydraulic hoses, be sure to
bleed off any residual pressure in the hoses and in
the Hydraulic Tank.
• 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 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 proce-
dure.
• Keep the clearance at the pin connecting section to
0.5 mm or less by using the shim.
Air Bleeding Operation
1. Start the engine and let it idle for about 5 minutes.
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.
