NEVER replace components of the track
or track frame without consulting the wear
limitation charts in the manufacturers service
TRACK REMOVAL (fig. 6-29).Steps for the
removal of the track are as follows:
1. RELEASE TRACK TENSION. Either by
manually backing off the track adjuster or loosening the
vent screw on the hydraulic track adjuster.
2. REMOVE THE MASTER PIN. The master pin
can be identified by a locking device or hole drilled in its
end that distinguishes it from the other pins in the chain.
Move the tractor backward slowly or, on some models,
forward to bring the master pin just below the level of
the drawbar. Place a block under the grouser on a shoe
that allows the master pin to be centered on the front
idler. With the master pin centered on the front idler,
remove any locking device. If the master pin had a
locking device, the pin can be removed by using a
sledgehammer and a soft metal driftpin. Should the pin
be drilled, a portable press must be used to remove the
pin. Do not lose the bushings, which may drop out with
3. REMOVE THE TRACK FROM THE
CARRIER ROLLERS AND IDLER. Slowly move the
tractor forward or backward away from the loose ends
of the track. Make sure no one is in the way of the tractor
or the loose end of the track when it falls off the sprocket
or front idler.
4. MOVE THE TRACTOR OFF THE TRACK.
Place a plank at the rear of the track. The plank should
be about the same thickness as the track, yet narrow
enough to fit between the track frame and guards, and
long enough so that the entire tractor can rest on the
After removing the tracks, always see that
the tractor is securely blocked while repairs
are being performed.
Anytime a track is removed, thoroughly inspect
the track frame components for excessive wear and
Removal, disassembly, and
replacement vary by model and manufacturer. Consult
the manufacturers service manual for exact
tracks, back the tractor off the plank and onto the new
tracks so the drive sprocket properly meshes with the
track rail. Continue backing until the tractor is just
ahead of the rear end of the track. Then place a bar in
the track (fig. 6-30), and help the track climb over the
sprocket, carrier rollers, and idler as the tractor is
driven forward. When the track comes together, install
the master pin and any locking device. Once the track
is together, adjust the track tension using the
manufacturers recommended procedures.
