REGULAR MAINTENANCE
RUBBER CRAWLER
Rubber crawler tension must be checked regularly.
Especially, when the machine is new, the rubber
crawlers extend quickly due to following reasons:
- When the rubber crawlers are new, they extend
quickly.
- Tightness of the rubber crawler become loose due
to the sprocket fitness.
For adjusting the rubber crawler, proceed as follows:
1. Place machine on a level surface of the vehicle body
2. Use a jack to elevate the crawler so that one side of
the machines tracks can hang free and loose.
WARNING
Be careful that the machine does not fall from the jack
and is secure.
3.Loosen the crawler's lock nuts.
4 Turn the crawler bolt, and adjust so that the clearance
between crawler and wheel (illustration ) is about
10-15 mm (wheels in parallel).
Idle wheel
Track roller
5. Tighten the lock nuts securely.
CAUTION 1
Re-tighten the crawler tension within first 10-20
hours operation.
CAUTION 2
The crawler tension on both sides should be same so
that the crawler drives straight.
CAUTION 3
If the rubber crawler is not tensed correctly,
life of the rubber crawler is shortened and trouble
happens on the parts.
If the crawlers are tensed too much, too much
friction will reduce the life of the crawlers.
The machine will also not drive efficiently.
So therefore check that the tension is correct
regularly and adjust if necessary.
