25. Procedures for Maintenance
3-23
25-2-1. Checking the rubber crawlers
Rubber crawlers in the following condition require repair or
replacement. Ask your dealer to repair or replace them.
Height of lugs
• As the lug height "a" is reduced by wear, the tractive
force decreases.
If "a" becomes 0.2 in. (5 mm) or less, replace the crawler
with a new one.
• If two or more links of the steel cord inside the crawler
are exposed due to wear of the lugs, replace the crawler
with a new one.
Rubber crawler steel cord breakage
If half or more of either of the steel cords is broken, replace
the rubber crawler with a new one.
Separation of the core metal of the rubber crawler
If the core metal of the rubber crawler separates even at
one place, replace the rubber crawler with a new one.
Rubber crawler tension
If the rubber crawler tension is habitually loose even after
grease is injected, the grease adjuster may be defective in-
ternally. Ask your dealer to repair the grease adjuster.
