OTHER ADJUSTMENTS AND REPLACEMENTS 62
A Track seam
The ends of the rubber track are joined with a seam.
When adjusting the tracks, the seam must be
positioned on the top midway between the idler and
the sprocket. By machines equipped with an upper
roller, the seam mark should be positioned over the
upper roller.
If the seam is positioned incorrectly, the tracks will be
tensed to loosely, and a further readjustment will be
necessary.
A
Rotate the track after adjustment one to two times to
check the tension. To loosen the rubber tracks, follow
the same method as for steel tracks.
A Additionally following points are to be observed when
adjusting rubber tracks.
(1) If the track slackens more than 25 mm, readjust
them.
(2) Check track tension 30 hours after initial use and
readjust if necessary. Check and adjust thereafter
every 50 service hours.

Special Information when Using Rubber
Tracks
1. When turning, make a slow swing turn. Avoid spin
turns to reduce lug wear and entry of dirt.
2. The relief valve may be activated if too much dirt and
sand clog the tracks. In this case move the machine for
a short distance straight backwards to let the earth and
sand fall off, then a turn can be made.
3. Avoid using rubber track on riverbeds, stony
underground, ferro-concrete and on iron plates. The
rubber can damage as well as increase wear on the
tracks.

Steel Tracks

Track shoe plate tension
1. Loosen bolt (1) and remove the cover (2).
2. Apply grease (4) to the grease nipple (3).
3. To check the track tension, the track must be lifted
from the ground as shown. The track tension is correct
if the clearance between the outer end of the track
roller and the track interior surface corresponds to the
dimension specified in the table below.
To avoid serious injury or death:
A Do not work under the machine in this
condition.
