How to Remove a Track
Assembly
Note: Perform this procedure on a firm, level
surface with the boom in the stowed position.
1 Select a track assembly to remove. Loosen and
remove as many sprocket retaining fasteners as
possible from the hub adapter.
2 Drive the machine in either direction just enough
to access the remaining fasteners. Do not
remove the retaining fasteners.
3 Chock the tracks at the opposite end of the
machine to prevent the machine from rolling.
4 Center a lifting jack of ample capacity
(20,000 lbs / 10,000 kg) under the drive chassis
between the tracks.
5 Lift the machine until the tracks are off the
ground and then place jack stands under the
drive chassis for support.
6 Attach a lifting strap from an overhead crane to
the center-point of the track assembly, above
the sprocket.
7 Remove the remaining sprocket retaining
fasteners from the hub adapter.
8 Carefully remove the track assembly from the
drive hub and set aside.
Crushing hazard. The track
assembly could become
unbalanced and fall when removed
from the machine if not properly
supported by the overhead crane.
How to Replace the Track
1 Remove the track assembly from the machine.
See How to Remove a Track Assembly.
Note: The sprocket is comprised of two halves.
Before removing the track assembly from the
machine and to ease the removal of the sprocket,
drive the machine until one complete half of the
sprocket is located above the undercarriage of the
track assembly.
2 Loosen the grease plug on the track tension
cylinder to relieve the track tension. Clean up
any grease that has spilled.
3 Remove the 2 sprocket retaining fasteners.
Remove the sprocket half from the track
assembly.
4 Carefully remove the track from the
undercarriage.
5 Use an overhead crane to lay the undercarriage
on its side with the drive sprocket bearing
assembly facing upward and the track tension
cylinder towards the ground.
