MAINTENANCE
Increasing Track Tension
NOTICE
The standard value is low, so be careful not to tighten the rubber shoe too much.
Prepare a grease pump.
1. Pump in grease through grease fitting (2) with a grease pump.
2. To check that the correct tension has been achieved, run the
engine at low idle, move the machine slowly forwards (7 to 8 m
(23.0 to 26.3 ft)), then stop the machine.
3. Check the rubber shoe tension again, and if the tension is not
correct, adjust it again.
4. If the tension is still low after supplied grease, the rubber shoe
needs to be replaced or the seal in the cylinder needs to be
replaced. Ask your Komatsu distributor for replacement.
