MAINTENANCE
When Required
5. Remove the rubber crawler from the idler
first, and then from the sprocket.
Take great care in handling rubber
crawlers, because they are very heavy.
Installation
1. Engage the rubber crawler with the
sprocket, and place the rubber crawler on
the idler.
2. Start the engine and turn the rubber
crawler slowly to install the rubber crawler
onto the idler securely, using a lever.
3. Stop the engine and confirm that the
rubber crawler is fully engaged with the
sprocket, the rollers and idler.
4. Referring to the step (2) on the previous
page, change the connecting locations of
the hydraulic hoses connected the auto-
tension valve (1), to return those to the
original state before the removal of the
rubber crawler.
5. Start the engine and check that the rubber
crawler tension is sufficient. Then lower
the machine to the ground.
6. Check the hydraulic hoses for oil
leakage.
