Replace Rubber Track
WARNING:
• Do not loosen valve (1) too quickly or too much
as high-pressure grease in the adjusting
cylinder may spout out. Loosen carefully,
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.
During this procedure, the high power track
adjuster may suddenly release the front idler
with extreme force, potentially resulting in
personal injury or death.
• After the rubber track is removed, the front idle
will become free to remove. 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 Track
1. Lower the bucket and blade to raise both tracks off
ground, as shown. Place blocks under machine frame
to support the machine.
2. Slowly turn valve (1) counterclockwise 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.
