The Honda 14100-ZK6-870 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 correct valve timing and reliable engine operation. Verify your engine's serial number against the fitment table before ordering, as Honda supersedes camshaft components at serial breaks within the GX390 line.
Key Features
- OEM Valve Timing Accuracy — as a genuine Honda part, this assembly is machined to the precise lobe profile and journal dimensions the GX390 engine requires for correct intake and exhaust timing throughout the RPM range.
- Direct OEM Replacement — engineered to the same specifications as the original, this assembly installs without modification and interfaces correctly with the GX390's existing pushrods, lifters, and timing components.
- GX390 Fitment — confirmed for GX390 horizontal shaft engines; check your serial number against the fitment table to confirm the correct supersession for your production run.
- Restored Engine Performance — a worn camshaft causes lost compression, rough running, reduced power output, and excessive valve noise; replacing it with this assembly restores proper valve lift and engine response.
The camshaft is the component that controls when the engine's intake and exhaust valves open and close. Driven by the crankshaft via a gear set, it rotates at half engine speed and uses precisely shaped lobes to push the lifters and pushrods that actuate the valves in sequence. When a camshaft wears, the lobe profiles flatten, reducing valve lift and disrupting timing — symptoms include loss of power, rough idle, excessive valve clatter, and hard starting. Replacing a worn camshaft assembly restores the valve events the engine was designed around, bringing compression and power back to specification.
