Verify part number 11976139450 against your machine's parts manual before ordering to confirm fitment for your specific unit.
Key Features
- Genuine OEM Electrical Specification — Manufactured to the precise switching threshold and circuit resistance required by the STXD6i and HTXD6i engine management systems.
- Direct-Connect Replacement — Matches the original connector, thread pitch, and port size for a straight swap with no adapters or additional hardware.
- Confirmed Fitment — Sourced directly for the STXD6i and HTXD6i hydrostatic ride-on trowel series.
- Protects Engine Integrity — An accurate oil pressure signal keeps the engine protection system functioning correctly, preventing undetected low-oil conditions that can cause serious internal damage.
- Safety-Critical Component — This switch feeds the engine's low-oil shutoff circuit; installing a correctly rated OEM unit ensures the protection system responds at the right pressure threshold.
The oil pressure switch monitors engine oil pressure and sends a signal to the machine's warning or shutdown system. When oil pressure drops below a safe operating level, the switch triggers an alert or cuts engine power to prevent catastrophic engine damage. A faulty or failed switch can either allow the engine to run unprotected during a low-oil event or cause nuisance shutdowns that interrupt work — making prompt replacement with a correctly rated part essential to keeping the machine operating safely.
