WARNING:
The pressure inside the cylinder of the track adjuster
is high. Do not loosen valve (1) quickly or loosen it
too much as valve (1) may fly out or high-pressure
grease in the adjusting cylinder may spout out.
Slowly loosen valve (1) while keeping body parts and
face away from valve (1). Never loosen grease fitting
(2).
When removing the rubber track, do not allow
anyone to stand in front of the front idler. Extremely
strong force is being applied in the track adjuster. It
may potentially result in personal injury or death.
After the rubber track is removed, the front
idle will become free. If the front idle comes off
unexpectedly, personal injury and/or death may
result. Be sure to remove the rubber track only after
taking appropriate measures to prevent the front
idler from coming off.
Removing Rubber Crawler
1. Lower the bucket and blade to raise one track off the
ground, as shown. Place blocks under machine frame to
support the machine.
2. Slowly turn valve (1) to allow grease to escape from the
grease outlet.
3. Insert two or three steel pipes into the gaps among
lower rollers, track frame and rubber track and slowly
rotate the track in reverse to lift the rubber track off the
idler. Apply horizontal force to pry the rubber track off
the idler. Before completely removing the rubber track
from the front idler, take an appropriate measure to
prevent the front idler from coming off. Then, remove
the rubber track.
