Key Features
- Engine-Specific Sealing Material — Engineered to the crush and sealing specifications of the Cummins B3.9 engine's drain plug interface, ensuring a leak-free seal after every oil change.
- Genuine OEM Part — Sourced directly from Genie, this washer meets the same standards as the component originally installed on the machine — no guesswork on material grade or thickness.
- Direct Service Replacement — Seats squarely against the Cummins B3.9 oil pan drain plug with no rework or fitment adjustment needed during routine oil service.
- Broad S-Series Compatibility — Fits the Genie S-100, S-105, S-120, and S-125 telescopic boom lifts equipped with the Cummins B3.9 engine.
- Protects Engine Integrity — A failed or reused crush washer can allow oil seepage at the drain plug, leading to oil loss and potential engine damage on high-reach booms operating in demanding conditions.
An oil drain washer — sometimes called a drain plug gasket or crush washer — seats between the oil pan drain plug and the engine block to create a leak-tight seal when the plug is torqued down. On the Cummins B3.9 engine, this small component plays a critical role in preventing oil loss during and after routine engine oil services. Reusing a deformed or worn washer is a common cause of slow oil seepage at the drain plug; replacing it with a fresh washer each service interval ensures the seal compresses correctly and holds under operating pressure and vibration.
