Bearings Inspection





1. Inspect the bearing rollers and races for the following conditions:

* Pitting

* Scoring or grooves

* Excessive wear or other damage





Note:
Heat discoloration ranges from a faint yellow to a dark blue color. This discoloration may result from an overload or improper lubrication. Excessive heat causes softening of the rollers and races. Bearings or races with sign of heat discoloration must be replaced.
