🔍 Key Concepts

• Roots-type blower construction (rotors, casing, end plates, seals) • How lubrication is normally supplied to blower lobes (is it direct or indirect?) • What a thin oil film on the lobes usually tells you about where the oil came from

💭 Think About

• Ask yourself: Are Roots blower lobes supposed to be directly lubricated, or are they designed to run dry with close clearances? • Which component, if it leaked, would allow oil to migrate from the ends of the blower onto the lobes? • Which choice describes a condition that would physically place oil on the lobes, rather than something that just affects timing or cylinder lubrication?

✅ Before You Answer

• Verify how rotor bearings and their oil seals are arranged in a Roots blower • Confirm whether proper lubrication would normally be visible on the lobes themselves • Consider whether excess cylinder lubrication would show up inside the cylinders, the exhaust, or on the blower lobes
