Gearbox Lubrication Analysis

Clark Testing also has the capabilities to conduct lubrication analysis on transmission and gearbox fluids. Our lubrication lab can provide information on physical properties and chemical analysis lubricants, hydraulic fluids and grease. Clark’s lab features the specialized FZG testing for analysis of anti-wear characteristics and load carrying capabilities of lubricants.

FZG Gear testing simulates misaligned gear set operating in the selected lubricant bath and subjected to 12-14 stages of torque load. The fluid performance is determined by inspection for scuffing or scoring of the gear teeth between each load stage which indicates excessive wear and therefore a breakdown in fluid performance.

Vehicle & Component Dynamometer Testing

Environmental conditions for Off-road testing can be simulated with high/low temperature, accelerated corrosion/salt and sand/road-dust. Custom control and data acquisition of torque, speed, vibration and temperature.
