6.12.7 Transfer Case Inspection and Service
Whenever servicing the vehicle, conduct a visual
inspection of the transfer case. A few moments spent
doing this can help prevent further problems and
downtime later.
Inspect the transfer case in its entirety, especially the
main casting, for any cracks, dents or other damage.
Look for oil seepage or leaks around the drive shaft
flange mounts. Check all bolts for proper torque.
While the vehicle is under warranty, JLG does not
recommend the servicing of gears, shafts or bearings
inside the transfer case. Attempts at disassembly of
these internal transfer case items may void the warranty,
cause damage to other parts and to the transfer case
casting (housing) itself.
Note: Contact your local Lull distributor or the JLG
Service Department at (877) 554-5438 or
(717) 485-6657, if internal transfer case repair is
required during the warranty period.
If service of internal transfer case components is required
and the transfer case is not under warranty. Refer to the
ZF Model TB92-I4 Transfer Case Operating and Repair
Manual, JLG P/N 8990495 (ZF part number
5871.134.002), or consult an authorized ZF repair center
or dealer.
