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.
