3. Drive Chain, Axle and Sprocket Inspection
The condition of the drive chains should be checked after the
first 50 hours of operation and every 150 hours thereafter.
To inspect, block the loader securely with all four wheels
clear off the ground. Remove both the front and rear
wheels. On reassembly torque the wheel nuts to 100-110 ft.
lbs. (136-149 N m). Remove the inspection cover on the
side of the chain drive housing.
Inspect the chain for any sign of wear, damage or excessive
looseness. Inspect the sprockets for any sign of damage or
excessive wear. Inspect the lubricating oil for signs of
contamination. Check the axle bearings for loss of bearing
preload. If necessary adjust the bearings for zero end play.

SYSTEM MAINTENANCE
1. Oil Level Check
Check the oil level of the hydraulic reservoir with the
machine on a level surface with the lift arms down and the
bucket flat on the ground. Open the rear door and check
the oil level sight glass (Fig. 4.6A). If oil is apparent the
level is satisfactory.
2. Adding Oil
To add oil, remove the oil filler cap located at the top of the
oil reservoir (Fig. 4. 6B). Check the filter screen in the filler
neck for signs of damage. Add 10W30 or 20W50API
Classification SE/ CD engine oil until oil is visible in the
oil level sight glass (Fig. 4.6A).
To avoid personal injury,
lower the lift arms, shut off
the engine, raise the seat bar
and cycle the hydraulics to
ensure they are locked. Then,
unlatch the seat belt and exit
the loader. Do not enter or
exit with the engine running
unless as specified in this
manual or under specific
service and backhoe
operating procedures.
