In the lubrication loop, after pumping, the lube oil passes through which components before reaching the LO header?

• A. Strainer and Oil Cooler
• B. Strainer and Filter
• C. Oil Cooler and Heater
• D. Strainer and Heater

Answer: (A)

When oil is pumped in the lubrication loop, it first passes through a strainer to remove debris that could damage bearings or clog small passages. It then goes through an oil cooler to remove excess heat, keeping the oil at the proper viscosity for effective lubrication. After these stages, the oil moves to the LO header for distribution to the bearings. Heaters are used in some setups to raise oil temperature, but in this path the combination of a strainer followed by the oil cooler is the correct sequence before reaching the header.
