During the machine operation, listen for unusual squeaking and for unusual squealing. This can indicate a dry joint.
Check the machine for dry joints weekly. Check for dry joints immediately after machine operation. After machine operation, lightly touch the end of each track pin or bushing. Touch the track pin or the track bushing with the back of your hand. Make a mark on any dry track pin joint that is very hot to the touch.
Do not hit the ends of the track pins with a sledge hammer in order to loosen the track joints.
Striking the end of a track pin introduces a significant amount of end play into the track joint and can result in early failures.
Consult your Caterpillar dealer's Custom Track Service expert if you detect dry joints or leaks. Your Caterpillar dealer's Custom Track Service expert can perform track inspection.
