Maintenance & Inspection
To keep a vehicle running properly, it is important to per-
form preventive maintenance on the vehicle components.
This ensures the vehicle and its subassemblies will operate
properly throughout their useful life. To cover preventive
maintenance completely, you must review the following
subjects in detail.
• Inspect the axle:
• Check the oil level - See “Lubrication” on page 3.
• Inspect under the vehicle for loose/missing bolts -
Replace any missing or broken bolts with the proper
part from the Illustrated Parts List. Tighten any loose
bolts to the torque specifi cations outlined in this
publication.
• Check the axle for lubricant leaks - Any lubricant leak
could cause a catastrophic failure. Check for leaks at
mating surfaces and plugs. Make sure the lubricant
is not being blown back from the engine or another
vehicle component.
• Changing the Lubricant
!
WARNING
REMEMBER TO BE CAREFUL WHEN CHANGING
THE LUBRICANT, AS IT MAY BE HOT.
• See “Lubricant Intervals” on page 3.
• Use the correct “Lubricant Type” on page 3.
• Use the proper amount of oil noted in the “Lubricant
Capacity” on page 3.
• Follow the carrier procedures outlined in “Draining
Carrier” on page 4 and “Filling Carrier” on page
5.
• Follow the wheel end procedures outlined in
“Draining Gearbox” on page 6 and “Filling
Gearbox” on page 6.
• Verify the oil is to the proper level as explained in
“Checking Carrier Oil” on page 4 and “Checking
Gearbox Oil” on page 5.
Lubrication
With any product containing gears, lubrication is possibly
the most important component eff ecting the product life
cycle. It is critical to use the correct lubricant, follow oil
change intervals, and check the oil level regularly.
Lubricant Type
Due to the duty cycles imposed on equipment, a multi-
grade lubricant 80W90 with service level API GL5 and
approved as meeting US MIL-L-2105 D specifi cation is
recommended for the carrier housing and gearbox.
Avoid mixing diff erent oil types, even if from the same
brand name, to avoid compatibility issues that can cause
seal materials to deteriorate.
Failure to use the required lubricant may aff ect perfor-
mance and warranty coverage.
Lubricant Capacity
Carrier & wheel ends - 5 qts (4.7 L )
Gearbox - 1.25 qts (1.2 L)
Lubricant Intervals
The lubricant intervals vary depending on the type of vehi-
cle, operating duty cycle, and application.
Under normal operating conditions:
Oil Changes: After fi rst 100 hours, then every 500 hours
Oil Level Check: Every 50 hours
