Multiquip KS31103101 Oil Level Sensor EY40

The Multiquip KS31103101 Oil Level Sensor EY40 is a genuine OEM component designed for EY40 and QP-40TA series equipment. Sourced directly from Multiquip, this sensor is built to the exact specifications required to protect your engine from low-oil conditions. Confirmed fitment covers the EY40 engine and QP-40TA trash pump, making it a straightforward service replacement for operators and technicians working with this equipment.

Key Features

• Genuine OEM Sensing Accuracy — Engineered to trigger at the correct oil level threshold for the EY40 engine, ensuring the low-oil shutoff responds exactly as designed.
• Direct Drop-In Replacement — Matches the original sensor's connector, thread pitch, and mounting configuration for a clean installation with no adaptation.
• Confirmed Fitment for EY40 and QP-40TA — Verified for use on EY40-powered equipment including the QP-40TA trash pump series.
• Engine Protection You Can Count On — A functioning oil level sensor is your engine's last line of defense against catastrophic low-oil damage; a worn or failed sensor leaves the engine running unprotected.
• Safety-Critical Compliance — Replacing a failed oil level sensor with a genuine OEM part ensures the automatic shutoff system operates within its intended parameters, protecting both the machine and the operator.

The oil level sensor monitors the engine's oil level in real time and triggers an automatic shutoff when oil drops below a safe operating threshold. This protection prevents the engine from running in a low-oil condition that would otherwise cause rapid internal wear or seizure. When the sensor fails, the engine loses this safeguard entirely — making prompt replacement with a correctly specified part essential to safe, continued operation.
