INSPECTION AND MAINTENANCE PROCEDURES

3. INSPECTING CRAWLER TENSION

Unequal tensions of the crawlers may cause the
machine to deviate from the travelling path. Make
sure the crawlers are equally tensioned. Always
adjust the tension of the rubber crawler after the first
10 to 20 service hours.
(1) If crawler is too tight, the rolling friction on the

surface idler sprocket contacting with the bear-
ing increases, scoring occurs on the crawler link
pin and the resistance is increased, resulting in
the reduction of travelling ability.

(2) If the crawler is too slack, it may slip off the

sprocket. Resistance increases when going in
reverse and the travelling ability of the machine
is reduced.

Inspection

(1) Insert a grease gun into the grease nipple and

pour the grease to strain the crawler.

(2) For loosening the crawler, loosening the car-

tridge valve, the grease in the cylinder automati-
cally comes out.

※

Confirmation of inspection (checking for air locks)

Before straining the crawler, loosen the cartridge valve and make sure grease
comes out by pushing the front idler to the cylinder.  Then tighten the valve and
add grease again.
