The Honda 14100-ZM3-010 Camshaft Assembly is a genuine OEM component designed for GX22 and GX31 horizontal shaft engines, the FG100 tiller, WX10 water pump, HHE31 stick edger, HHT31 trimmer, and UMK422 and UMK431 trimmers. As a direct Honda OEM part, this camshaft assembly carries the exact profile and tolerances specified for these applications, ensuring proper valve timing from the moment it is installed. Always confirm your unit's serial number against the fitment table before ordering, as Honda supersedes parts at serial number breaks and more than one variant may cover this lineup.
Key Features
- Genuine OEM Valve Timing — machined to Honda's exact lobe profile, ensuring intake and exhaust valves open and close at the precise moment the engine requires for proper combustion and power delivery
- Broad Cross-Equipment Fitment — a single assembly covers GX22 and GX31 horizontal shaft engines, the FG100 tiller, WX10 water pump, HHE31 stick edger, HHT31 trimmer, and UMK422 and UMK431 trimmers, including a wide range of serial numbers within those models
- Verify Your Serial Number — Honda releases superseded part numbers at defined serial breaks; check your machine's serial number against the fitment table to confirm this is the correct assembly for your unit
- Restores Lost Performance — a worn camshaft causes misfires, rough idle, poor throttle response, and hard starting; replacing it with part number 14100-ZM3-010 brings valve timing back to spec and restores consistent engine output
The camshaft is the engine's timing nerve center. Driven off the crankshaft, it uses precision-ground lobes to push open the intake and exhaust valves at exactly the right point in each combustion cycle, then allows them to snap shut on the spring's return. In these small-displacement Honda engines — used across tillers, trimmers, edgers, and water pumps — a healthy camshaft is what separates crisp throttle response and clean idle from rough running and hard starts. When the lobes wear or the cam gear sustains damage, valve timing drifts out of spec and the engine loses compression, power, and the ability to run smoothly under load.
