2 Disassembly
1 Precautions
Begin motor disassembly only after thoroughly reading the precautions below.
[1] When performing disassembly, always wear protective devices such as a helmet, goggles and safety shoes.
[2] Use the specified tools when performing disassembly.
[3] Remove all lines connected to the motor and remove the motor from the mother machine only after making sure that the machine is on a level surface and there are no external forces acting on rotating parts so that the mother machine does not operate uncontrollably when the motor is removed.
[4] To prevent foreign matter from entering the lines and motor when removing the motor from the mother machine, sufficiently clean off mud and dirt adhered around the motor before removing lines connected to the motor.
[5] When removing lines connected to the motor, hydraulic oil from inside the lines will spray out. For this reason, remove these lines only after removing pressure from inside the lines and preparing an oil pan. To prevent injuries
due to the motor falling when transporting it by lifting the motor with a liftcrane, lift the machine with the eyebolts mounted in the positions indicated in the diagram below.
[6] The motor is filled with hydraulic oil. Before disassembling the motor, prepare an oil pan and drain the hydraulic oil from the motor.
[7] To prevent injuries during disassembly, prepare a waist-high, stable work platform to perform work on.
[8] The motor comprises high-precision parts. For this reason, foreign matter adhering to parts can be damaging.
Motor disassembly should be done in an inside space without dust, and mud and dirt should be prevented from adhering to parts.
[9] The motor comprises high-precision parts. For this reason, dents and scratching on part surfaces can be damaging.
Be very careful when handling parts during disassembly and do not create any dents or scratching.
[10]To prevent personal injury and damage to parts during disassembly, do not force disassembly of parts which are especially tight to disassemble.
2 Tightening torque
The tightening torque for each fastening section are indicated in the text.
3 Travel motor disassembly procedure
Perform disassembly by observing the precautions listed in 2. (1) and following the procedure indicated below
[1] Removal of cap assemblies (2-6).
Secure the motor on top of the stable work platform, loosen the 8 hexagon socket head bolts (2-6-6) and remove the cap assemblies (2-6). Next, remove the spring seats (2-5), springs (2-4), and spring seats (2-3).
NOTICE:
The cap assemblies (2-6) are pressed out by the springs (2-4). On the other hand, if the cap assemblies
(2-6) do not come off even when the bolt is loosened, hit the cap with a plastic hammer. For this reason, observe the following precautions when working.
• Loosen the hexagon socket head bolts (2-6-6)
evenly.
• Loosen the hexagon socket head bolts (2-6-6) while pressing down the cap assemblies (2-6).
• When hitting the cap assemblies (2-6), do so with the bolts (2-6-6) only partially loosened.
If the bolts (2-6-6) are removed, there is a danger of the cap assemblies (2-6) flying out and injuring someone.

EXCERPT:
Install the locking bushings (4). Install the screws (3) through the locking bushings and the pin. Using a set of feeler gauges, check that there is a clearance of 1
to 2.5 mm between the mounting bracket and the cylinder rod mounting eye. If necessary, remove the screws and the pin and add or remove one or more shim(s) as required to obtain the correct clearance.
Install the pin and the screws. Install the first nut (2) on the screw and tighten until the nut touches the locking bushing. Loosen the nut a quarter of a turn and, using two wrenches, install the second nut (2) to lock the first nut in position. Remove the sling from the boom cylinder.

MAIN HYDRAULIC PUMP
Removal and installation
STEP 1
Park the machine on hard, flat ground. Lower the attachment to the ground.
STEP 2
Release pressure in the hydraulic system and in the hydraulic reservoir (see Section 8000).
STEP 3
Disconnect the battery ground (-) cable (1) from the battery.
STEP 4
Remove the access panel (1) below the hydraulic reservoir.
STEP 5
Put an appropriate container under the hydraulic reservoir. Open the drain cock and drain the hydraulic fluid. Close the cock.
STEP 6
Remove the engine hood (1) then the protective grille (2).
STEP 7
Disconnect all the hoses from the quick coupling control block (A). Remove the block (A) from the panel (B).
STEP 8
Remove all the retaining screws (A) from the panel (B), then remove the panel (B).
STEP 9
Remove the circlip (1) fastening the silencer pipe to the turbocharger.
NOTE: All the engine and the exhaust system to cool down before starting any disassembly.
STEP 10
Remove the four retaining nuts from the silencer circlips, then remove the two circlips.
NOTE: When installing, tighten the nuts to the torque specified on page 3.
STEP 11
Remove the silencer assembly (1) from the machine.
STEP 12
Remove the three retaining screws (1) from the silencer bracket, then remove the silencer bracket.
NOTE: When installing, tighten the screws to the torque specified on page 3.
STEP 13
To facilitate proper installation, attach identification tags to all hoses and electrical connections of the main hydraulic pump and the pilot pump.
STEP 14
Remove the pipes, the hydraulic hoses and the electrical connections. Seal all hoses and unions of the main pump as well as those of the pilot pump.
STEP 15
Install an appropriate lifting apparatus on the hydraulic pump. Do not leave any slack so that the pump can be supported once the fastening screws of the pump are removed.
STEP 16
Remove the retaining screws of the hydraulic pump.
NOTE: When installing, tighten the screws to the torque specified on page 3.
STEP 17
Remove the hydraulic pump from the motor and put it away from the machine. Place the hydraulic pump on a clean workbench using suitable brackets.
NOTE: Carry out the following step only if a new hydraulic pump needs to be installed.
STEP 18
Remove the connections of the hydraulic pump that has just been removed and install them on the new hydraulic pump. Remove and install the connections one after another to avoid improper installation of the connections on the new hydraulic pump.
NOTE: For installing the hydraulic pump, proceed in the reverse order to that of removal. Replace all rings with new rings.
STEP 19
Remove the four screws and washers (1). Remove the cover (2) and the O-ring from on top of the hydraulic reservoir. Scrap the O-ring. Fill the hydraulic reservoir with hydraulic fluid (see Section 1002) up to a level in between the “high” and “low” marks on the visual gauge. Install the cover with a new O-ring, fasten it using four screws and washers (1).
Connect the ground (-) cable (1) of the battery.
STEP 20
NOTE: Always drain the air out from the hydraulic pump before starting the engine. If the air has not been drained out, the pump can get damaged. For the procedure, see Section 8000.
NOTE: Before carrying out any work with the machine, operate the swing, travel and the attachment for five minutes with the engine at idle speed. Check that there are no leaks in the system, check the oil level in the hydraulic reservoir. Top up if necessary, refer to Section 8001.

Hydraulic systems – Boom hydraulic system
Boom cylinder – Prepare – For disassemble
Preparations prepare the following before starting disassembly.
1. Work platform preparation
Prepare a sufficiently spacious, solid and stable work surface so that parts will not fall or move during work.
2. Tool and materials preparation
Prepare the tools and materials shown on the following pages.
General work precautions
1. Thoroughly clean any dirt or mud from the outside walls of the cylinder before starting disassembly.
2. Each part has been manufactured with a high degree of precision, so be careful to not let parts bump each other or fall when handling them.
3. If parts are struck or pried off with excessive force during work because they are tight, this may cause burrs or damage which causing reduction in performance or oil leaking. Perform work carefully and thoroughly.
4. If a cylinder is left disassembled, humidity and dirt can cause rust on parts. If a pause in the work is unavoidable, be careful to prevent rust and keep off dust.
Maintenance standards
Replace sliding parts and seal parts as follows.
1. Bushing
When 1/4 of the circumference is worn brown over the entire length.
2. Seals and slide rings
Replace with new parts when the cylinder is disassembled.
3. Pin bushing
When there is severe seizing.
4. Piston rod
When the piston rod is bent 0.5 mm (0.0197 in) / 1 m (3.281 ft) or more.
