Extendable Axles
The extendable axles are used to widen the foot
print of the drive chassis for stability.
How to Shim the Extendable Axle
Measure each wear pad. Replace
the pad if it is less than
(11 mm) thick. If the pad is more
than 7 /
perform the following procedure.
1 Extend the axle.
2 Remove the wear pad mounting fasteners.
3 Install the new shims under the wear pad to
obtain zero clearance and zero drag.
4 Use a round punch to align the shim to the
wear pad. Install the mounting fasteners.
5 Extend and retract the axle through an entire
cycle. Check for tight spots that could cause
scraping or binding.
Always maintain squareness
between the outer and inner axle
tubes.
How to Remove the Inner Axle
This procedure requires specific
repair skills and a suitable
workshop. Attempting this
procedure without these skills
and tools may result in death or
serious injury and significant
component damage. Dealer
service is strongly recommended.
1 Extend the axle to be removed.
2 Loosen the wheel lug nuts. Do not
remove them.
3 Block the wheels on the opposite end of the
machine, and then center a lifting jack under
the axle to be removed.
