Track frame
The track frames
(1)
attach to the machine chassis on
each side. All the track components except the drive
sprockets attach to the track frames.
Carrier rollers
The carrier rollers
(2)
mount on the top of the track frames.
The carrier roller supports the track chain between the
drive sprocket and idler. The carrier roller helps main-
tain alignment of the chain between the idler and drive
sprocket.
Track chain
The track chains
(3)
include a number of link assemblies
connected together to form a complete chain. Shoes bolt
to the track chain
(3)
to provide traction for the machine.
Drive sprocket
The drive sprockets
(4)
transmit engine power to the
tracks. The drive sprockets rotate the track chain around
the undercarriage assembly. The drive sprockets
(4)
do
not support the weight of the machine.
Track rollers
The track rollers
(5)
mount to the bottom of the track
frames. These rollers carry the weight of the machine on
the track chains.
Idler
The idler
(6)
carries the track chain around the front of
the track frame. This assembly can slide forward or back
on the track frame against the recoil spring to absorb any
shock loads. These shock loads can be from changes in
the terrain or temporary material buildup on the tracks.
