The oil supply in a rotary gear primer increases the efficiency of the primer and acts as a preservative.

The oil supply in a rotary gear primer increases the efficiency of the primer and acts as a preservative.

• A. False
• B. No effect
• C. Increases wear
• D. True

Answer: (D)

Lubrication and surface protection keep the rotary gear primer operating smoothly. The oil supply coats the gears and internal surfaces, reducing friction between moving parts, which lowers heat and wear and helps the mechanism prime more efficiently. That same oil film acts as a preservative, guarding against corrosion and helping keep contaminants from causing damage between uses. Because of that, the primer works more reliably and lasts longer. Without oil, gears would wear faster, efficiency would drop, and priming could become unreliable.
