MAINTENANCE
REPLACING THE TRAVEL MOTOR GEAR
OIL
• Stop the engine and allow the machine
to cool down before performing
maintenance.
· The travel motor is hot immediately
after the engine is stopped. Touching
it will cause burns.
· The gear oil is also hot and under high
pressure immediately after the engine
is stopped.
Be careful when loosening the plugs.
Working on the machine under these
conditions could result in burns or
injuries.
• The pressure in the reduction gear case
of travel motor may cause oil or the plug
to fly out. Loosen the plug slowly to
release the pressure.
IMPORTANT: If the percentage of the
traveling time within the total operating
time is high, replace the gear oil earlier
than the specified time.
AFTER THE INITIAL 250 HOURS (ONLY FOR NEW MACHINES)
1. Set the travel motor so that plug (1) is at
the very bottom.
2. Place a pan under the plug (1).
3. Remove the plugs (1), (2) and (3) and drain
the oil.
4. Rewrap the plugs with new sealing tape.
5. Tighten the plug (1).
· Plug (1) tightening torque: 46 to 51 N·m
(34 to 37.6 ft-lb)
6. Add oil through the hole of the plug (3)
until oil flows out of the hole of the plug
(2).
7. Tighten the plugs (2) and (3).
· Plug (2) tightening torque: 12 to 18 N·m
(8.8 to 13.3 ft-lb)
· Plug (3) tightening torque: 46 to 51 N·m
(34 to 37.6 ft-lb)
