What is the ideal oil temperature for continuous operation in the TH-73A?

• A. 90 °C
• B. 100 °C
• C. 105 °C
• D. 110 °C

Answer: (D)

The ideal oil temperature for continuous operation in the TH-73A is 110 °C. This temperature ensures optimal performance of the engine and reduces the risk of overheating or inadequate lubrication, which can lead to engine wear and potential failure. Operating at this temperature allows the oil to maintain its viscosity and effectively carry away heat from critical engine components, ensuring smooth operation and longevity of the engine. Temperatures significantly lower than this may hinder lubrication effectiveness, while temperatures higher than 110 °C can risk damaging the engine or cause breakdown of the oil. Maintaining the oil temperature within the specified range is crucial for safety and reliability during operations.
