The Multiquip 12000ZF6L04 Cylinder Assembly GX390 is a genuine OEM component designed for the MRH800GS walk-behind roller. Sourced directly from Multiquip, this assembly carries the same specifications as the original part built into your machine. Confirmed fitment for MRH800GS equipment ensures a straightforward, like-for-like installation. When you need to restore your roller to full operating condition, the 12000ZF6L04 delivers the exacting fit that only a genuine OEM part can provide.
Key Features
- Genuine OEM Construction — Manufactured to the same tolerances and material grades as the original cylinder assembly, ensuring the GX390 engine bore geometry is preserved for correct compression and power output.
- Direct-Fit Replacement — Engineered to match the original mounting points, bore dimensions, and port locations of the GX390 engine as installed on the MRH800GS, allowing straightforward swap-out without machining or modification.
- Confirmed MRH800GS Compatibility — Verified fitment for the Multiquip MRH800GS walk-behind roller, so you can order with confidence knowing this is the correct assembly for your machine.
- Restored Engine Performance — A compromised cylinder causes loss of compression, increased oil consumption, and hard starting. Replacing it with this genuine assembly brings combustion efficiency back to original operating levels.
- Fuel System and Ignition Integrity — The cylinder assembly forms the structural core of the combustion chamber; using a correctly spec'd OEM part maintains proper spark plug seating and fuel-air ignition timing.
The cylinder assembly is the central structural and functional component of the GX390 engine's combustion system. It houses the piston bore, coolant passages, and port architecture that together govern compression, power stroke, and exhaust flow. When a cylinder becomes worn, scored, or cracked, the engine loses compression and cannot generate consistent power — symptoms include hard starting, rough running, excessive oil burn, and ultimately engine failure. Replacing the cylinder assembly with a genuine OEM part restores the original bore geometry and ensures all mating components, including the piston, rings, and head gasket, seat and seal correctly.
