IMPORTANT: Always dispose of hydraulic fluids
according to environmental laws or take to a recy-
cling center for proper disposal. DO NOT pour onto
the ground or down a drain.
4. Remove plug (F) to allow for venting as the oil
drains.
5. Remove plug (H) and allow the oil to drain
completely.
6. Clean and replace plug (H). Tighten securely.
7. Remove plug (G).
8. Fill the travel motor gearbox through plug (F)
hole with the correct grade and type oil until it
reaches the level of plug (G) hole.
NOTE:
Refer to “Fluids/Lubricants Types and
Capacities” on page 35 for travel motor gearbox oil
specifications. Motor gearbox oil capacity is
approximately 0.8L (0.84 qts.).
9. Clean and replace plugs (F and G). Tighten
securely.
10. Test the drive system and check for leaks.
Track Maintenance
Inspect the tracks daily for damage and wear.
IMPORTANT:
To avoid damaging the tracks and
to ensure maximum track life, refer to “Rubber
Track Use Cautions and Tips” on page 91.
Observe the following conditions to extend track
life:
• Avoid traveling or turning on broken stone, jag-
ged rock, metal or other material that could dam-
age or cut the tracks.
• Avoid traveling on riverbeds or areas with soft
rocks that could become stuck in the tracks,
which could cause damage to the tracks or cause
the tracks to slip off.
• Avoid using the machine on the seashore. Sea
salt can corrode the metal cores inside the tracks.
• Immediately wipe any spilled fuel, oil, salt or
chemical solvents off of the tracks, as these sub-
stances can corrode the coupling in the metal
cores in the tracks, causing corrosion and peeling
• Avoid traveling on freshly paved roads or on hot
surfaces (e.g. fires, metal sheets exposed to direct
sunlight, etc.). Hot surfaces can damage the lugs
or cause irregular wear.
• Avoid moving earth in area where the tracks may
slip, which can cause excessive lug wear.
Track Replacement
Keeps hands clear from between the track and
the idler when installing tracks. Crushing of
body parts and amputation can result.
1. With the machine running and the drive system
not moving, remove tension cylinder stop (K,
Fig. 150) on the side on the machine with the
track to be replaced.
