STARTING TORQUE
Heavy motion at low temperature
Revisit base-oil viscosity, thickener and plastic compatibility around cold starting conditions.
DIAGNOSTIC FRAMEWORK
Possible causes and checks
Review these possible factors against observed conditions.
Cold viscosity and lubricant dose
Separate cold-soaked start-up from running behaviour and compare controlled doses to assess drag.
Clearance & material changes
Record the polymer grade, tolerances and contacts and compare mechanism resistance before/after thermal changes.
Wear after life testing
At the same temperature, compare initial and post-cycle torque, tooth surfaces and lubricant location.
COMPARATIVE EVALUATION
Comparative test sequence
- Record the baseline
- Compare one factor
- Retest candidate materials
- Review life-test results
