MAINTENANCE
When Required
Replacing the Rubber Crawlers
¡
If you must work beneath the raised
machine or equipment, always use
wood blocks, jack-stands or other rigid
and stable supports. Never get under
the machine or working equipment if
they are not sufficiently supported.
This procedure is especially important
when working on hydraulic cylinders.
¡
If maintenance must be performed with
the engine running, always work as a
2-person team with one person sitting
in the operator's seat while the other
works on the machine.
¡
When performing maintenance, be
sure to keep your body and clothing
away from moving parts.
Removal
1. Fully release the tension of the rubber
crawler.
Refer to page 113 “Inspecting and
Adjusting the Crawler Tension”.
2. Use the working equipment to lift the body.
3. Set an iron pipe (1) in the rubber crawler
and turn the sprocket slowly in the reverse
direction.
4. Turn until the iron pipe (1) is directly next
to the idler and the rubber crawler lifts away
from the idler, then stop turning the
sprocket.
5. Slide the rubber crawler sideways and
remove it from the crawler frame.
Remove the other rubber crawler using the
same procedure.
