The Honda 14431-ZA0-010 Valve Rocker Arm is a genuine OEM component designed for GX360 horizontal shaft engines, EL5000 and EX5500 generators, the ES6500 generator, EV4010, EV6010 and EVD4010 RV generators, and H4514, HT3813 and HT4213 lawn tractors. As a direct Honda OEM part, it is manufactured to the same specification as the original, ensuring correct valve actuation geometry and reliable service life. Confirm your machine's serial number against the fitment table before ordering, as Honda supersedes rocker arm part numbers at production breaks.
Key Features
- Genuine Honda OEM Valve Timing Accuracy — manufactured to Honda's original specification, preserving the correct rocker ratio and contact geometry that govern how fully each valve opens and closes
- Broad OEM Fitment — covers GX360 horizontal shaft engines, EL5000, ES6500 and EX5500 generators, EV4010, EV6010 and EVD4010 RV generators, and H4514, HT3813 and HT4213 lawn tractors; verify your serial number against the fitment table to confirm the correct application
- Drop-In Replacement — matches the original pivot bore, pad radius and pushrod seat so this part installs without machining or modification
- Engine Health at Stake — a worn rocker arm causes erratic valve lift, leading to loss of compression, rough running, increased fuel consumption and, if left unchecked, accelerated camshaft and valve stem wear
The valve rocker arm sits between the pushrod and the valve stem in the overhead-valve (OHV) valvetrain. As the camshaft lobe pushes the pushrod upward, the rocker arm pivots on its shaft and transfers that motion downward to open the intake or exhaust valve against spring pressure. When the lobe passes, the valve spring closes the valve and the rocker returns to its resting position. This cycle repeats thousands of times per minute, so the rocker arm's contact surfaces are subject to constant wear. A rocker arm that has worn beyond its service limit will produce valve lash outside the specified range, robbing the engine of its breathing efficiency, reducing power output, and causing the characteristic tapping noise that signals a valvetrain in need of attention.
