The Honda 14100-ZK6-880 Exhaust Side Camshaft Assembly is a genuine OEM component designed for GX390 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the same specifications as the original and is the correct replacement when the exhaust-side camshaft requires service. Honda supersedes parts at serial number breaks, so confirm your engine's serial number against the fitment table before ordering to ensure part number 14100-ZK6-880 is the right match for your unit.
Key Features
- Genuine OEM Camshaft Precision — manufactured by Honda with the correct lobe profile and timing geometry to maintain proper exhaust valve lift and duration on GX390 horizontal shaft engines.
- Exact OEM Replacement — this assembly installs as a direct replacement for the original exhaust-side camshaft, eliminating the guesswork of aftermarket fitment.
- Serial Number Verification Recommended — Honda updates camshaft part numbers at production breaks; check your GX390 engine serial number against the compatibility table to confirm this is the correct assembly for your serial range.
- Valve Timing Integrity — a worn or damaged exhaust-side camshaft causes poor exhaust valve timing, resulting in lost compression, rough running, increased fuel consumption, and accelerated engine wear.
The exhaust-side camshaft is a precision-machined shaft that drives the exhaust valves in the GX390 engine. As the camshaft rotates, its lobes push against the rocker arms at precisely timed intervals, opening the exhaust valves to expel combustion gases from the cylinder. When the camshaft lobes wear down or the shaft is damaged, exhaust valve timing is compromised — leading to symptoms such as loss of power, hard starting, increased fuel consumption, and excessive engine heat. Replacing a worn camshaft assembly with a genuine Honda OEM part restores correct valve timing and keeps the engine running at its intended output.
