7P-7858 7P7858 Bushing for D6R Track Type Tractor

Regular Inspection (The Most Critical Step):

Measure for Wear: The most important maintenance task is regularly measuring the bushing's outer diameter (the part the sprocket contacts). Use a dedicated bushing wear gauge or a large outside micrometer. Compare your measurements to the "wear limit" specified in the Caterpillar service manual.
Inspect for Visual Damage: Look for signs of cracking, gouging, or abnormal wear patterns. Check the seals on lubricated bushings for damage, cuts, or extrusion.

This 7P-7858 bushing is used for D6R dozer.
