The Genie 237774GT is a genuine OEM Perkins 403D-11G Oil Drain Plug built for Genie and Terex portable light towers, including the AL4000, RL4000, TML-4000, AL4, and RL4. As a direct OEM replacement, this plug is manufactured to match the original specification for the Perkins 403D-11G engine found in these units, ensuring a correct fit without modification. Keep a spare on hand to minimize service time during routine oil changes and engine maintenance.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original specification for the Perkins 403D-11G engine, ensuring correct thread form, sealing surface, and material grade.
- Direct Engine Match — Engineered specifically for the Perkins 403D-11G powerplant, so this plug installs cleanly without rework or adaptation.
- Broad Light Tower Fitment — Compatible with AL4000, RL4000, TML-4000, AL4, and RL4 light towers, covering a wide range of Genie and Terex portable lighting equipment.
- Leak-Free Service Intervals — A correctly seated oil drain plug maintains a secure closure at the drain point, preventing seepage between oil changes and keeping the engine topped to its proper level.
- Operational Safety — A failed or cross-threaded drain plug can lead to oil loss and engine damage on a running light tower; replacing it with the correct OEM part restores a dependable seal.
An oil drain plug seals the drain port at the base of the engine oil sump, keeping engine oil contained between service intervals and allowing controlled drainage during oil changes. When the plug is damaged, cross-threaded, or missing its sealing surface, oil can leak steadily from the sump — leading to low oil levels, accelerated engine wear, and potential engine failure if left unaddressed. Using the correct OEM plug for the Perkins 403D-11G engine in your light tower ensures the thread engagement and seating surface are right for that specific application, giving you a reliable seal every time the sump is drained and refilled.
