Step 1
Common observations
- Wear/polishing: lubricant, contamination and alignment
- Scoring: temperature, sliding and oil film
- Pitting: stress, hardness, finish and cycles
- Breakage: peak load, root, defects and support
- Overheating: losses, oil, cooling and bearings
- Backlash growth: wear, bearing and housing
Step 2
Preserve evidence
- Document before cleaning
- Sample lubricant and contamination
- Photograph assembly and contact
- Measure backlash and alignment
- Keep mating parts together
- Collect load, temperature and maintenance history
Step 3
Corrective action
- Correct the verified cause
- Validate under representative duty
- Avoid changing only material or hardness without system review
