Key Features

• Genuine OEM Construction — Manufactured to exact Multiquip tolerances, ensuring the Oil Alert Cylinder Assembly responds to oil level changes with the sensitivity the system was calibrated for.
• Direct Drop-In Replacement — Designed to install directly into the existing Oil Alert housing without modification, maintaining proper sensor alignment and sealing contact.
• Broad Cross-Equipment Compatibility — A single OEM part number covers multiple machine families including MVC90H plate compactors, MC64P/S and WM70S/P mixers, MP-series masonry saws, and QP205SH centrifugal pumps.
• Protects Engine from Low-Oil Damage — A properly functioning Oil Alert cylinder triggers automatic engine shutdown before oil starvation can cause irreversible internal damage, preserving engine longevity across high-demand jobsite cycles.
• Critical Safety Function — The Oil Alert system is a primary engine protection mechanism; using the correct OEM cylinder assembly ensures the shutdown threshold remains accurate and the system performs as intended.

The Oil Alert Cylinder Assembly is the sensing element within Honda's Oil Alert engine protection system. It monitors engine oil level and, when oil drops below the safe operating threshold, signals the engine to shut down automatically before damage can occur. A worn, cracked, or degraded cylinder can cause either false shutdowns that interrupt work or — more critically — a failure to trigger shutdown when oil is genuinely low, leaving the engine exposed to seizure from oil starvation. Replacing a suspect cylinder assembly with the correct OEM part restores the system's accuracy and keeps the engine protection circuit working as designed.
