Multiquip 12000ZH8426 Cylinder Barrel Assembly Oil Alert

The Multiquip 12000ZH8426 Cylinder Barrel Assembly Oil Alert is a genuine OEM engine component designed for MVC82VHW, MVC82VH, and MVC90H plate compactors, as well as QP205SH centrifugal pumps and GAC2.2HZ gasoline powered generators. As a direct Multiquip OEM part, 12000ZH8426 is manufactured to the exact tolerances required by the original engine specification — ensuring proper fit and function without modification. This assembly integrates the cylinder barrel with the oil alert system, making it a critical combination component for both engine compression and low-oil protection. Verify your model code against the fitment list below before ordering to confirm compatibility.

Key Features

• Genuine OEM Construction — Manufactured to Honda engine tolerances for correct bore geometry, wall thickness, and oil alert port alignment specific to this cylinder barrel assembly.
• Integrated Oil Alert System — Combines the cylinder barrel and oil alert sensor housing in a single assembly, ensuring the low-oil shutdown circuit interfaces correctly with the engine block.
• Broad Equipment Compatibility — Fits MVC82VHW, MVC82VH, and MVC90H plate compactors, QP205SH centrifugal pumps, and GAC2.2HZ gasoline powered generators — all sharing the same Honda engine platform.
• Restores Full Compression — A worn or scored cylinder barrel leads to compression loss, hard starting, and reduced compaction force; replacing with this OEM assembly brings the engine back to proper operating pressure.
• Low-Oil Protection Preserved — The built-in oil alert function is essential for engine safety — a damaged or bypassed assembly leaves the engine without automatic shutdown protection during low-oil conditions.

The cylinder barrel is the core bore of the engine block through which the piston travels, maintaining the compression seal necessary to generate power. On this Honda-engine assembly, the oil alert system is integrated directly into the barrel housing, connecting to a sensor that monitors oil level and triggers an automatic engine shutdown before internal damage can occur. When the barrel wears, scores, or cracks — or when the oil alert port is damaged — the engine loses compression efficiency and low-oil protection simultaneously, making this combined assembly a critical replacement item for restoring both power output and engine safeguarding.
