The Genie 237776GT is a genuine OEM Oil Pressure Switch designed for Perkins 403D-11G engine-equipped Genie machines, including light towers, rough-terrain scissor lifts, and articulating boom lifts. As a direct OEM replacement, this switch is built to the same specification as the original, ensuring a correct, trouble-free installation. Cross-reference part number 237776GT against your machine's parts manual to confirm it is the right component for your unit before ordering.
Key Features
- Genuine OEM Specification — Manufactured to Genie's original engineering specification for the Perkins 403D-11G engine, delivering correct switching thresholds and electrical compatibility.
- Direct OEM Replacement — Connects to the existing wiring harness and engine port with no modification, restoring the original switching function exactly as designed.
- Broad Fitment Across Genie Equipment Families — Fits Genie light towers (AL4000, RL4000, TML-4000, AL4, RL4), rough-terrain scissor lifts (GS-2668 RT, GS-3268 RT), and articulating boom lifts (Z-45/25, Z-45/25J IC Power, Z-34 IC).
- Protects the Engine — A functioning oil pressure switch monitors engine oil pressure and triggers a warning or shutdown when pressure drops below a safe threshold, protecting the engine from damage caused by low oil pressure conditions.
- Operational Safety — On engine-powered aerial equipment, a correctly operating oil pressure switch is a critical safeguard. A failed or bypassed switch removes the machine's ability to detect a loss of oil pressure before serious engine damage occurs.
An oil pressure switch monitors the engine's lubrication pressure and sends a signal to the machine's warning system or shutdown circuit when pressure falls outside the acceptable range. On Perkins 403D-11G powered Genie equipment, this switch serves as an early warning against oil starvation, which can cause rapid and severe engine damage if left undetected. A faulty switch — one that reads incorrectly or fails to trigger — leaves the engine unprotected, while a switch stuck in the warning state can cause nuisance shutdowns. Replacing a suspect switch with the correct genuine OEM part, Genie 237776GT, restores the full integrity of the engine protection system.
