Extend the Adjustable Axles and clean the telescoping driveshafts.
Adjustable Axles 3-4m
The rear axle of the 3-4m adjustable axle is
fitted with splined telescoping drives shafts
between the differential centre and dropleg
inputs.
These shafts do not have a shield or guard so
they must be cleaned and greased regularly.
When performing maintenance on the
adjustable axles, 3 of the needle valves can
be closed allowing controlled extenting and
retracting of the axle being serviced.
Before extending or retracting an axle, ensure
that the wheel is raised sufficiently off the
ground using a rated axle stand or jack.
DO NOT attempt to extend or retract axle while the
extending or retracting axle wheel is On the ground.
Failure to ensure the wheel is Off the ground before
extending or retracting is attempted will create excessive
pressure on the wheel assembly & can cause damage.

Telescoping Driveshaft
To Clean & Re-apply Grease
1 Fully extend the axles using the procedure
explained in Chapter 6, 'Operation'.
2 Turn engine off and chock all wheels
3 Using a strong degreaser or wax & grease
remover, generously coat the splines. Use
a brush to loosen the grease and dirt.
4 Use compressed air to clean splines.
Ensure safety glasses or a face shield are
worn.
5 Once clean, apply a generous coat of
grease to all surfaces of the splines.
Recommended grease: Kluberpaste 46

Drop Legs
Dropleg oil levels should be checked regularly.
Replace dropleg oil at the first 50 hour service
to remove manufacturing contamination.
Thereafter, replace oil every 500 hours.
Refer to the specification provided in the
'Maintenance Schedules' of this chapter.
Dropleg Oil
Drop legs incorporate an oil bath sump in
which chains run & carry oil for the chains,
sprockets & bearings.
Each idler shaft bearing housing utilises
a sump to ensure bearings are always
lubricated.
When cleaning telescoping driveshafts and ONE wheel
is lifted OFF the ground, the adjustable axle can be
adjusted to the desired width providing the OTHER 3 axle
adjustment cylinder valves are CLOSED. Adjust & measure
the width. Repeat the procedure for each wheel.
Dropleg oil level/fill plug (top arrow) & drain plug (bottom
arrow).
To Check Dropleg Oil Levels:
1 Remove the dropleg oil level/fill plug.
2 Check the oil level. Oil level must be just
below the level/fill plug.
3 If required, add more oil.
4 Refit & tighten the level/fill plug.
5 Repeat the procedure for each dropleg.
To Change Dropleg Oil:
1 Place a container below the drain plug
at the base of the dropleg to collect the
draining oil.
2 Remove the drain plug to empty old oil.
3 After the oil is completely drained, refit and
properly tighten the drain plug.
4 Refill the dropleg with recommended oil.
Refer to the specification provided in the
'Maintenance Schedules' of this chapter.
5 Repeat the procedure for each dropleg.
