Sprocket Roller Removal and
Installation
The tools required for sprocket roller removal and
installation are listed in table 12-4 below. Use
manufacturer-recommended tools whenever
possible.
Sprocket Roller Removal
Table 12-4
Note: The rollers should be inspected every 50 hours for
rotation and wear-through. The rollers on the drive
sprocket are easily replaceable. The track DOES NOT
need to be removed to replace these rollers.
Note: In order to remove the sprocket rollers and pins, you
must remove the torsion axle retaining bolts and washers,
then slide the undercarriage away from the chassis slightly
(approx. 1”, 2.54 cm). This will provide clearance for the
sprocket bolts to be removed for roller/pin replacement.

sprocket.

3. Inspect the rollers for wear and replace as
necessary. The steel pin will normally not need
replacing unless the roller has worn completely
away and the steel pin is worn from engaging
the track (fig. 12-32A & B).
