The document provides instructions for removing and installing a swing motor, disassembling and assembling a swing motor, removing and installing a reduction gear, and disassembling and assembling a reduction gear. For the swing motor: it describes removing hoses, bolts, and the motor assembly. For disassembly it describes removing plates, seals, shafts, bearings, and other internal components. Reassembly is the reverse of disassembly. The reduction gear section similarly describes removing and installing the gear assembly, and disassembling/assembling internal components like gears, carriers, seals and shafts.

1. REMOVAL AND INSTALL OF MOTOR
REMOVAL
Lower the work equipment to the ground
and stop the engine.
Operate the control levers and pedals
several times to release the remaining
pressure in the hydraulic piping.
Loosen the breather slowly to release the
pressure inside the hydraulic tank.
Escaping fluid under pressure can
penetrate the skin causing serious
injury.
When pipes and hoses are disconnected,
the oil inside the piping will flow out, so
catch it in oil pan.
Disconnect hose assembly (2).
Disconnect pilot line hoses (3,4,5,6,7,8,9).
Sling the swing motor assembly (1) and
remove the swing motor mounting bolts
(10).
Motor device weight : 250kg (550lb)
Remove the swing motor assembly.
When removing the swing motor
assembly, check that all the piping have
been disconnected.
INSTALL
Carry out installation in the reverse order
to removal.
Bleed the air from the swing motor.
Remove the air vent plug.
Pour in hydraulic oil until it overflows from
the port.
Tighten plug lightly.
Start the engine, run at low idling and
check oil come out from plug.
Tighten plug fully.
Confirm the hydraulic oil level and check
the hydraulic oil leak or not.
