In incidents where excessive foreign particles have entered the gear guard or where continuous contamination has occurred, it is imperative to conduct proper gear cleaning and relubrication, according to AGMA 9005 requirements, to ensure no damage was caused to the gear.
Problems caused by contaminated lubrication
- Abrasive wear on gear teeth
- Excessive vibration
- Buildup in the root of the gear tooth can cause the pinion and gear not to mesh properly
A proper cleaning and flushing program, as per ASTM E2905, needs to be developed to minimize gear teeth contamination. This helps the asset to reach the expected 25-year lifecycle as per the stringent industry standard AGMA 6014 – Gear Power Rating for Cylindrical Shell and Trunnion Supported Equipment.
