Key Features
- Genuine OEM Sealing Integrity — Manufactured to Perkins 1004-42 engine specifications, this washer provides the correct crush profile and material compliance for a leak-free drain plug seal.
- Direct Engine Service Fit — Seats against the oil pan drain port exactly as the original, requiring no trimming, shimming, or rework during installation.
- Broad Genie Fleet Coverage — Fits Perkins 1004-42-powered S-series telescopic booms and GTH-series telehandlers, making it a practical stock item for mixed Genie fleets.
- Leak Prevention at Every Service Interval — A correctly seated drain washer eliminates weeping or dripping at the drain plug — a common consequence of reusing a deformed or worn washer across multiple oil changes.
- Engine Protection Where It Counts — Oil loss from a compromised drain seal can cause rapid engine oil pressure drop; replacing this washer at every drain is a low-cost step that protects a high-value powertrain component.
The oil drain washer sits between the engine oil pan drain plug and the threaded drain port, creating a compressed metal-to-metal or soft-metal seal that prevents engine oil from escaping past the plug. As the drain plug is torqued, the washer deforms slightly to fill any micro-imperfections in the seating surface — a process that is by design single-use. Reusing a washer that has already been crushed reduces sealing effectiveness and increases the risk of an oil leak developing between service intervals, which can go undetected on a machine operating at height and lead to unplanned engine wear or failure.
