4. 6 FINAL DRIVE MAINTENANCE
1. Oil Level Check
The loader has two independent final drive housings.
Check the lubricating oil level with the loader on a level
surface. Remove the check plug (Fig. 4.6A) located on the
front of the loader to determine the oil level. The oil level
should be checked after 50 operating hours and every 150
hours thereafter. It is recommended the oil be changed
after 1000 operating hours or if it shows signs of
contamination.
2. Adding Oil
Add oil with the loader on level ground. Remove the oil
level check plug (Fig. 4.6A) on the final drive housing.
Remove the seat and hydrostatic shield. Remove the filler
cap (Fig. 4.6B). Fill with 10W30 API Classification SJ to
the level of the check plug.
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
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 both the idler sprocket and axle
bearings for loss of bearing preload. If necessary adjust the
bearings for zero end play.
Check the axle seals for leaking oil or damage. Replace
seals at first sign of problem.
