Powertrain analysis

Powertraing close-up

This service monitors transmission, differential and final drive oils for premature wear, contamination and oil condition


Powertrain analysis helps detect gear or transmission problems and lubricant contamination before they can result in costly downtime or repairs. The analysis is applicable to transmission, differential or final drive (gear) components in all types of mobile equipment, and includes testing to help you ensure long equipment life and optimal performance.

Test Purpose Importance of test
Metals To determine the presence and levels of metallic content in the oil, including contaminants and wear particles The level of metals helps determine if equipment components are wearing or if harmful contamination is entering the oil. The level of metals that are part of the additive chemistry are also reported
Oxidation To determine the level of lubricant oxidation and deterioration

Oxidation can mean:

  • Increased wear and corrosion
  • Shorter equipment life
  • Increased viscosity
  • Excessive deposits and plugging
Particle Count Analysis To measure the level of particulate contaminants in the oil
  • Cleanliness is a critical factor in the running of hydraulic and circulating oil systems
  • Debris can interfere in the fine tolerances of the system’s pumps and valves or cause premature wear
Total Acid Number (TAN) To measure acidic oil oxidation by-products An elevated Total Acid Number may indicate increased oil acidity resulting from increased oil oxidation
Viscosity To determine the oil’s resistance to flow
  • An increase in viscosity may be due to high soot or insoluble content, water contamination, or admixture with higher viscosity fuel or lubricant
  • A decrease in viscosity may be due to water contamination, or admixture with lower viscosity fuel or lubricant
  • Both high or low viscosity may result in premature equipment wear
Particle Qualification (PQ) Index To determine ferrous metal fatigue failures and metal-to-metal contact not usually detectable with some spectrographic analysis PQ Index can detect at an early stage:
  • Anti-friction bearing wear
  • Plain bearing wear
  • Gear wear
Water To detect presence of water contamination Water contamination may cause severe corrosion and subsequent wear, poor oil film thickness or hydrogen embrittlement
