The Genie 839190GT is a genuine OEM Kubota Low Oil Pressure Switch built for a range of Genie light towers and boom lifts, including AL4000, AL5000, AL5HT, RL4, and Z-34/22 IC and Z-45/22 MP articulating booms. As a genuine OEM part, this switch is built to the same specification as the component it replaces, ensuring accurate sensing thresholds and a direct, no-fuss installation. Cross-reference part number 839190GT against your machine's parts manual to confirm it is the correct item for your specific unit before ordering.
Key Features
- Genuine OEM Quality — Sourced directly from Genie, this switch meets the original engineering specification for sensing accuracy and electrical compatibility — no guesswork on threshold calibration.
- Direct-Fit Replacement — Designed to install in the same location as the original switch, with matching connector and thread spec for a clean swap.
- Broad Genie Fitment — Compatible with Genie AL and RL series light towers as well as select Z-series articulating boom lifts, covering a wide range of Genie equipment.
- Critical Engine Protection — A functioning oil pressure switch alerts the operator or triggers a shutdown when oil pressure drops below a safe operating threshold, protecting the Kubota engine from damage caused by low lubrication.
- Operational Safety — On engine-powered aerial and lighting equipment, a failed or stuck pressure switch can mask a dangerous drop in oil pressure. Replacing a faulty switch with the correct OEM part restores the engine's ability to protect itself.
A low oil pressure switch monitors engine oil pressure and signals the machine's control system when pressure falls below a safe level. On Kubota-powered Genie equipment, this typically triggers a warning or an automatic engine shutdown to prevent internal engine damage. When the switch fails — whether it reads incorrectly or stops sending a signal altogether — the engine loses its primary protection against low-oil conditions, putting it at risk of serious mechanical damage. Replacing a worn or faulty switch with the correct OEM component restores that protection and keeps the engine monitoring system working as intended.
