from the machine. 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.
WARNING: An improperly supported machine can fall, causing death or
severe personal injury. Safely raise and adequately support
the machine so that it will remain stable and in place before
attempting to remove an axle.
WARNING: Hot hydraulic fluid can cause severe burns. Wait for the
hydraulic fluid to cool before servicing any hydraulic
component.
WARNING: Relieve hydraulic pressure before servicing any hydraulic
component. Escaping hydraulic fluid under pressure can
penetrate the skin, causing death or serious injury.
The front and rear axle assemblies differ in that the front axle assembly is
equipped with a parking brake mechanism and a limited-slip feature; the
rear axle has neither. The following steps outline a typical axle removal
procedure, suitable for either the front or the rear axle assembly.
Cleanliness is extremely important. Before attempting to remove the axle,
thoroughly clean the machine. Avoid spraying water or cleaning solution on
the stabilizer solenoids and other electrical components. If using a steam
cleaner, seal all openings before steam cleaning.
IMPORTANT: Clear the work area of all debris, unnecessary personnel,
etc. Allow sufficient space to raise the machine and to remove the axle.
1. Park the machine on a firm, level surface, level the machine, ground the
attachment, place the travel select lever in the (N) NEUTRAL position,
engage the parking brake, straighten all wheels and shut the engine
OFF.
2. Place an Accident Prevention Tag on both the ignition key switch and
steering wheel, stating that the machine should not be operated.
3. Open the engine compartment cover. Allow the engine, transmission
and hydraulic fluid to cool.
4. Disconnect the battery negative (-) cable at the battery negative (-)
terminal to prevent the engine from starting accidentally.
5. If the axle will be disassembled after removal, place a suitable
receptacle under the axle drain plug. Remove the drain plug and allow
the axle oil to drain into the receptacle. Transfer the used axle oil into a
suitable covered container, and label the container as “Used Oil.”
Dispose of used oil at an approved recycling facility.
6. Label, disconnect and cap the steering and brake lines at the axle.
Wipe up any spilled oil.
7. Block the front and rear of both tires on the axle that is not being
removed. Ensure that the machine will remain in place during axle
removal before proceeding.
