Multiquip 12000Z5T407 Cylinder Barrel Assembly

The Multiquip 12000Z5T407 Cylinder Barrel Assembly is a genuine OEM component designed for GA6HB, GA6HEB, MC12PH, and MVH408GH series equipment. As a factory-sourced part, it meets the exact dimensional and material specifications of the original component it replaces, ensuring proper fitment across this range of Multiquip gasoline-powered generators, mixers, and plate compactors. This assembly is the correct OEM-specified replacement when the original cylinder barrel is worn, damaged, or being rebuilt as part of a scheduled engine overhaul.

Key Features

• OEM Cylinder Tolerances — Manufactured to the precise bore diameter and surface finish specs required for proper piston-to-wall clearance and compression integrity.
• Drop-In Engine Fitment — Engineered to bolt directly into the engine block assembly without machining or modification, preserving correct head and piston alignment.
• Broad Model Coverage — A single genuine OEM part number covering GA6HB, GA6HEB, MC12PH, and MVH408GH equipment, simplifying parts sourcing across your fleet.
• Restored Compression and Power Output — A fresh cylinder barrel eliminates the blow-by and power loss that comes with a scored or worn bore, restoring the engine to full operating output.
• Genuine Multiquip OEM Quality — Sourced directly through Multiquip's authorized parts supply chain, ensuring material grade and dimensional accuracy consistent with the original build specification.

The cylinder barrel is the core structural and functional element of a reciprocating engine — it forms the combustion chamber walls within which the piston travels. A properly dimensioned barrel maintains compression, controls oil consumption, and allows the piston rings to seat correctly against the bore surface. When the barrel becomes scored, worn out of round, or corroded, the engine loses compression, burns oil, and delivers reduced power or fails to start reliably. Replacing the barrel assembly with the correct OEM part restores the engine's combustion efficiency and extends the working life of the entire power unit.
