The Honda 14100-Z1C-790 Camshaft Assembly is a genuine OEM component designed for GX390 horizontal shaft engines. Sourced directly from Honda, this assembly meets the exact specifications of the original part it replaces, ensuring the valve timing and lift characteristics your engine depends on remain exactly as engineered. This is the correct replacement for GX390 engines, and buyers should verify their engine serial number against the fitment table to confirm this is the right part for their specific unit.
Key Features
- Genuine OEM Valve Timing — as a Honda-sourced OEM part, this camshaft carries the exact lobe profile and timing specifications Honda engineers designed into the GX390, so intake and exhaust events happen at precisely the right moment in the combustion cycle
- Direct OEM Replacement — this assembly installs in place of the original camshaft with no deviation from Honda's design, maintaining correct valve lift and duration without compromise
- Built for GX390 Horizontal Shaft Engines — engineered specifically for the GX390, this camshaft is not a universal fit; confirm your engine model before ordering
- Serial Number Verification Recommended — Honda updates and supersedes internal components at specific serial number breaks; check your engine's serial number against the fitment table to ensure part number 14100-Z1C-790 is correct for your unit
- Restores Lost Power and Compression — a worn camshaft causes erratic valve operation, loss of compression, rough running, and hard starting; replacing it with this genuine assembly brings the engine back to its designed output
The camshaft is the component that controls when the intake and exhaust valves open and close during each engine cycle. Driven by the crankshaft through a gear set, it uses precisely shaped lobes to push the pushrods and rocker arms that actuate the valves at the correct moment. When a camshaft wears — through lack of lubrication, high hours, or contaminated oil — lobe profiles deteriorate, valve timing drifts, and the engine loses power, develops a rough idle, or becomes difficult to start. Replacing a worn camshaft with this genuine Honda assembly restores the valve events the GX390 was designed around, returning normal compression and clean combustion to the engine.
