RUBBER TRACK SHOE MAINTENANCE
* Rubber track shoe should be
repaired or replaced under the next
conditions.
* If is necessary to repair or replace it,
consult your IHI dealer.
1. Height of lugs
The rubber track shoe can be used even
if it is worn, however, if it is excessively
worn, the rubber track shoe is likely to be
slippery and more travel force is required.
If the remaining lug is less than 5 mm high,
replace it with brand-new one.
2. Exposure of Steel Cords
If steel cord is exposed because of weary
rubber or damage, replace it with brand-
new one.
3. Break of Steel Cords
When break of steel cord is detected,
replace it immediately. If you leave it as it
is, the rubber track shoe can be break
without expectation, which causes a
serious accident.
4. Crack of Covering Rubber
If a crack is 30 mm or more long and
8 mm or more deep, repair the cover
immediately. If steel cord appears even if
a crack is small, repair it immediately.
Otherwise, water may come into a crack,
which rusts steel cords and break the
rubber track shoe.
