The Honda 14751-ZL8-000 Valve Spring is a genuine OEM Valve Spring designed for a wide range of Honda engines and power equipment, including GC135, GC160, GC190, GCV135, GCV160, GCV170, GCV190, GCV200, GS160, GS190, and GSV190 engines, HRB216, HRB217, HRC216, HRN216, HRR216, HRS216, HRT216, HRX217, and HRZ216 lawn mowers, HS520 and HS720 single-stage snow blowers, FG400 and FG500 tillers, WN20 and WN30 water pumps, and EN2000, EN2500, EB2800, and EG2800 generators. As a genuine Honda OEM part, this Valve Spring is manufactured to the exact specification Honda engineering requires, ensuring the correct spring rate and seat dimensions for each application. Always confirm your unit's serial number against the fitment table before ordering, as Honda may use different valve spring specifications across serial ranges on the same model.
Key Features
- Correct Spring Rate — manufactured to Honda's OEM specification, delivering the precise tension needed to seat the valve cleanly and hold it closed against combustion pressure at the correct lift points
- Direct OEM Replacement — this Valve Spring installs in place of the original with no rework to the valve train; genuine Honda part number 14751-ZL8-000 ensures an exact dimensional match
- Broad Fitment — covers GC, GCV, GS, and GSV horizontal and vertical shaft engines, multiple Honda lawn mower lines, single-stage snow blowers, tillers, water pumps, and generators; confirm your model and serial number before ordering
- Restores Valve Train Performance — a fatigued or broken valve spring causes poor compression, rough running, loss of power, and hard starting; replacing it returns the engine to its full operating condition
A valve spring holds the engine's intake or exhaust valve firmly on its seat whenever the camshaft lobe is not actively opening it. By maintaining consistent closing force throughout the valve cycle, the spring ensures a gas-tight seal at the combustion chamber, which is essential for correct compression and efficient combustion. When a valve spring weakens through fatigue or breaks entirely, the valve may not seat fully, leading to compression loss, misfires, excessive fuel consumption, and in severe cases, contact between the valve and the piston.
