7.15 Drive Sprocket Rollers
Compact Track Loaders use rollers on
each drive tooth of the drive sprock-
ets. These rollers help minimize fric-
tion between lugs on the track and
the sprocket. Sprocket rollers should
be treated as wear items that are
inspected regularly 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 continue to function and perform as long as they are rotating.
Visually inspect rollers every 50 hours and replace any that show signs of crack-
ing or wear-through.
Drive sprocket removal and roller / pin replacement should be performed by your
local Terex dealer.
