Multiquip EM122 Cylinder Head

The Multiquip EM122 is a genuine OEM Cylinder Head designed for an extensive range of Multiquip and Whiteman equipment, including GA6HZ generators, MTX series rammers, MVC and MVH plate compactors, ride-on and walk-behind power trowels, rollers, pumps, mixers, and screeds. As a direct OEM replacement, this cylinder head is manufactured to the same specifications as the original component, ensuring a correct fit across all compatible model codes. Sourced directly through authorized Multiquip supply channels, the EM122 is the dependable choice when a precise, like-for-like replacement is required. Verify your model code against the fitment list before ordering to confirm compatibility.

Key Features

• Genuine OEM Construction — Manufactured to the same dimensional and material specifications as the original, ensuring correct combustion chamber geometry, port alignment, and sealing surface integrity.
• Direct Bolt-On Replacement — Matches original head bolt patterns and deck surface finish, allowing installation without machining or custom fitting on compatible models.
• Broad Cross-Equipment Fitment — Compatible with GA6HZ, GA3.6HZ, MTX60HD, MTX70HD, MTX70HDR, MTX80HDR, MVC82VH, MVC88VTH, MVH308GH, HTX44K4, HTX44K5, STX55Y6, and numerous additional Multiquip model codes.
• Restores Full Engine Compression — A worn or cracked cylinder head causes compression loss, overheating, and hard starting; replacing with the EM122 restores proper compression and combustion efficiency.
• Critical Safety Boundary — The cylinder head seals combustion gases and coolant passages; a compromised head can result in exhaust leaks or uncontrolled overheating, making correct replacement essential for safe operation.

The cylinder head is the upper closure of the engine's combustion chamber, housing the intake and exhaust valves, spark plug port, and the sealing surface for the head gasket. It plays a direct role in maintaining compression pressure, controlling airflow into and out of the cylinder, and dissipating heat from the combustion process. When a cylinder head cracks, warps, or develops a failed seating surface, the engine will lose compression, run poorly, overheat, or fail to start — making timely replacement critical to keeping the host machine operational.
