The Honda 14100-ZK7-870 Camshaft Assembly is a genuine OEM replacement designed for the GX120 horizontal shaft engine. Sourced directly from Honda, this component meets the exact engineering specifications of the original part and installs without modification. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and more than one camshaft variant may apply to the GX120 line.
Key Features
- Genuine Honda OEM — manufactured to Honda's original specifications for the GX120, ensuring correct lobe profiles, journal dimensions, and valve timing geometry right out of the box.
- Correct Valve Timing — an accurate camshaft profile governs precise intake and exhaust valve timing; a worn or damaged camshaft causes loss of compression, rough running, and reduced power output.
- Direct OEM Replacement — this Camshaft Assembly is a drop-in replacement for GX120 horizontal shaft engines, designed to mate with the existing valvetrain components without rework.
- Serial Number Verification Recommended — Honda updates camshaft part numbers across production runs; check your engine's serial number against the compatibility table to confirm this is the correct assembly for your unit.
The camshaft is a precision-machined rotating shaft that controls when the engine's intake and exhaust valves open and close. Driven by the crankshaft via a gear set, it uses its lobes to push the pushrods at precisely timed intervals, allowing the fuel-air mixture in and exhaust gases out. When a camshaft wears or its lobes become pitted, valve timing drifts, causing hard starting, rough idle, loss of compression, and significant power loss — problems that only worsen with continued operation.
