Adjustment of Crawler Shoe
Tension the crawler shoe
1. Fill grease through the grease nipple (2) of the check
valve (1) until the crawler shoe is tensioned properly.
2. Rotate the crawler forward and backward and check
tension. Re-adjust it if necessary.
•
Adjust the right and left crawler shoes evenly.
•
If the shoes are not tensioned properly, the
cylinders may be defective. Ask IHI’s service
dealer for repair services.
Loosen the crawler shoe
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 shoe forward and backward slightly
if grease is hardly discharged.
4. Tighten the check valve when the crawler shoes are
tensioned properly.

Be careful not to over-tighten the check valve.
5. Rotate the crawler shoe forward and backward and check tension. Re-adjust it if necessary.
•
When the crawler shoe 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.
•
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.
•
Do not bring your face or hand close to the check valve during adjustment.
