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.
At 50 hour intervals, shut the machine down as described in section 5.13 and
visually inspect rollers. Replace any that show signs of cracking or wear-through.
Drive sprocket removal and roller / pin replacement should be performed by your
local VT-70 High Output dealer.
