Adjustment of Crawler Track
Tension the crawler track
1. Fill grease through the grease nipple (2) of the check
valve (1) until the crawler track is tensioned properly.
2. Rotate the crawler forward and backward and check
tension. Re-adjust it if necessary.
x
Adjust the right and left crawler tracks evenly.

If the tracks are not tensioned properly, the
cylinders may be defective. Ask IHI’s service
dealer for repair services.
Loosen the crawler track
1. Remove dirt and soil from around the front idlers.
2. Loosen the check valve until grease is discharged (by
a maximum of one turn) little by little. Do not loosen it
when grease is discharged.
3. Rotate the crawler track forward and backward slightly
if grease is hardly discharged.
4. Tighten the check valve when the crawler tracks are

Be careful not to over-tighten the check valve.

When the crawler track is tensioned intensely, the internal pressure in the grease
cylinder is very high.
Grease may spout out or the check valve may spring out, causing a serious accident.
x
To relief the pressure, loosen the check valve gradually. Do not loosen it when grease
is discharged. (It should be loosened by a maximum of one turn.)

Grease may spout out at high pressure. Never loosen the grease nipple.
