7.15 Drive Sprocket Rollers
Rubber Track Loaders use
rollers on each drive tooth of
the drive sprockets. These
rollers help minimize friction
between lugs on the track and
the sprocket. Sprocket rollers
should be treated as wear
items that are inspected regu-
larly and replaced as needed.
The rollers (1) rotate on steel pins (2), limiting wear to the inside of
the rollers. As they wear, the rollers become thinner, but will contin-
ue to function and perform as long as they are rotating.
Visually inspect rollers every 50 hours and replace any that show
signs of cracking or wear-through.
Drive sprocket removal and roller / pin replacement should be per-
formed by your local Terex dealer.
