5.3.7 Axle Service and Troubleshooting
This section provides an easy reference guide covering
the most common problems that may occur during
operation of the axles.
Note: Contact the Sky Trak distributor or the JLG
Service Department at 1-877-554-5438 or
1-717-485-6657, if internal axle repair is required during
the warranty period.
Detailed axle service instructions (covering the axle,
differential, brakes and wheel-end safety, repair,
disassembly, reassembly, adjustment and
troubleshooting information) are provided in the ZF Axle
Repair Manuals. (Refer to Section 5.3.8, “ZF Axle Repair
Manuals.”)
The axle should be checked, serviced and repaired only
by experienced service technicians who are aware of all
safety instructions and particular component features.
WARNING:
Avoid prolonged engine
operation in closed areas without adequate
ventilation. Failure to properly ventilate
exhaust fumes can result in death or severe
personal injury.
WARNING:
Escaping hydraulic fluid
under pressure can penetrate the skin, causing
death or serious injury. Before starting the
engine, tighten all hydraulic connections and
remove all tools from the vehicle. NEVER
check for leaks using any part of the human
body; use a piece of cardboard or wood
instead. Wear heavy, protective gloves and
eye protection.
