ATTACHMENTS AND OPTIONS
Storage and Maintenance
Take care that no oil or grease sticks to the rubber. If it does,
wipe it off immediately.
Install rubber pad shoes and Road Liner corresponding to the
number of the links. If there is any missing pad or liner, the
rubber will be greatly deformed and damaged.
If rubber pad shoes or Road Liner has to be stored for a long
period, keep it indoors to avoid direct sunlight and rain.
Extent of Damage to Rubber
When traveling on a concrete pavement, rubber may stick to the
road surface, leaving a dark track behind. It is the time for
replacement.
The rubber is still usable, even if it does not look in good shape with part of the rubber chipped or cuts developed
on the surface, so long as damage has not developed all over the shoe or it does not damage a road surface.
Check Road Liner
If the road liners are in the following condition, they must be repaired or replaced, so please contact your Komatsu
distributor for repairs or replacement.
Height of Lug
If lug height "a" is reduced by wear, the drawer pull will drop. If
"a" is less than 5 mm (0.2 in), replace with a new part.
Replace Road Liner
When all the road liners of the machine need to be replaced, ask your Komatsu distributor to replace them.
When replacing only part of the road liner, use the special road liner removal tool. Please order the tool from your
Komatsu distributor.
