The Honda 14100-ZK3-880 Camshaft Assembly is a genuine OEM component designed for GX270 and GX340 horizontal shaft engines. As a direct Honda OEM part, it carries the exact lobe profile, journal dimensions, and timing geometry specified for these engines — no guesswork on fitment. This Camshaft Assembly is the correct replacement for both the GX270 and GX340 series; confirm your engine's serial number against the fitment table to ensure part number 14100-ZK3-880 is the right supersession for your specific build.
Key Features
- OEM Valve Timing Accuracy — genuine Honda manufacture ensures the camshaft lobe profile matches the original intake and exhaust timing specifications for the GX270 and GX340 engines, so combustion efficiency and power output are restored to spec
- Direct OEM Replacement — this Camshaft Assembly is engineered to drop into the engine in place of the original component, maintaining correct journal clearances and gear mesh without rework
- Fits GX270 and GX340 Horizontal Shaft Engines — verify your serial number against the compatibility table, as Honda issues supersessions at serial breaks and the fitment for your specific unit may vary
- Valve Train Integrity — a worn camshaft causes erratic valve actuation, loss of compression, rough running, and hard starting; replacing it with a genuine OEM assembly restores consistent valve lift and duration across the full RPM range
The camshaft is the component that opens and closes the intake and exhaust valves in sequence as the engine runs. Driven off the crankshaft via a gear set, it controls precisely when each valve opens, how far it lifts, and when it closes — timing that directly determines how efficiently the engine breathes and how much power it makes. On the GX270 and GX340, which use an OHV pushrod valvetrain, the camshaft also drives the engine's compression release mechanism, which eases starting by slightly holding the exhaust valve open during cranking. When the camshaft lobes wear, valve timing drifts, compression drops, the engine becomes difficult to start, and performance falls off noticeably — making this one of the most consequential internal components to replace with a genuine Honda part.
