Track Removal and Replacement
Removal
1 Position machine on a firm, level surface.
2 Raise the machine on the side to be worked on as
follows:
a Place a block of wood under one end of the shovel
and fully lower and tilt the shovel onto the block so
as to raise the front of the machine.
b Position blocks under the front and rear of the
chassis then raise the shovel to lower the
machine so that the chassis sits on the blocks as
shown at A.
Alternatively use a suitable jack to raise the
machine, taking care not to damage the chassis.
3 Remove the access cover and unscrew the grease
adjuster to release the track tension (see Section 3).
Collect and discard the grease. Use a lever to push
the front idler wheel fully in as shown at B.
4 Thread a sling through holes in the track between the
rear idler and the sprocket. Insert a suitable round
section steel bar between the sling and the track.
Using a hoist, raise the bar so as to rotate the track
slightly until the bar is positioned at the top of the
sprocket as shown at C.
5 Using the hoist, lift the track clear of the sprocket.
6 Unscrew the sprocket retaining bolts and remove the
sprocket as shown at D.
7 Position a support under the track to take up the sag
at the bottom.
8 Manoeuvre the track off the rear idler and away from
the machine.
