Track links
A number of track links (7) make up the track chain as-
sembly. Each link assembly consists of a right-hand and
a left-hand link. The track pin is hollow with Case Lu-
bricated Track (CLT) chains, bushings, and seals. Each
link assembly is bored at both ends to hold the pins and
the bushing that connect the two links. The bushing is a
pressed fit into each link. A pin is inserted through the
bushing. The next set of links is pressed onto the pin.
Track adjuster grease fitting
The track adjuster (8) is a grease-filled hydraulic cylinder
used to maintain or adjust track tension. Add grease or
remove grease from the track adjuster to change track
tension.

Track shoes
The track shoes (9) provide traction and flotation for the
machine.
Track guides
The track guides (10) correctly align the chain to the idler
and sprocket. The track guides also prevent the chain
from deviating off the idler and sprocket. The full rock
guide option helps prevent rocks and debris from entering
between the front roller and the idler, and between the
rear roller and the sprocket.
