Which Caterpillar machines is the 3178766 compatible with?

How often should the 3178766 be replaced?
Service life for the 3178766 depends on operating conditions and load. Replace it on inspection findings or at the interval your manual specifies rather than waiting for a failure.

When the 3178766 reaches the end of its service life, the symptoms tend to show up first as performance or wear issues. Look for:
- Knocking, rumbling, or whining under load

- Scored, pitted, or discolored bearing surfaces
