The Genie T113772GT is a genuine OEM Isuzu 4LE2 Oil Switch designed for Genie AL5000, AL5HT, AL5, and AL5 with Vertical Mast light towers. As a direct OEM replacement, this switch is built to the exact specification required by the Isuzu 4LE2 engine found in these light tower units. Cross-reference part number T113772GT against your machine's parts manual to confirm it is the correct item for your serial number before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie OEM specification for the Isuzu 4LE2 engine, ensuring correct calibration and a secure, leak-free connection at the engine block.
- Direct OEM Replacement — Installs directly in place of the original switch with no modification, preserving the integrity of the oil monitoring circuit on compatible light towers.
- Broad AL-Series Compatibility — Fits AL5000, AL5HT, AL5, and AL5 with Vertical Mast light towers, covering the core AL5 family powered by the Isuzu 4LE2 engine.
- Engine Protection — A correctly functioning oil switch monitors engine oil pressure and triggers a shutdown or alert before low-pressure conditions can cause internal engine damage.
- Operational Safety — On light tower equipment, engine oil pressure monitoring is a critical safeguard; a failed or inaccurate switch removes that layer of protection and should be replaced promptly.
An oil switch monitors engine oil pressure and sends a signal to the machine's warning or shutdown system when pressure drops below a safe threshold. On Isuzu 4LE2-powered light towers, this switch is the first line of defense against oil starvation — a condition that can cause rapid and severe engine damage if left undetected. When the switch fails, the engine loses its ability to report low-pressure conditions, leaving the unit running without protection. Replacing a worn or faulty switch with the correct OEM part restores that monitoring function and keeps the engine protected during extended operation.
