The Honda 35110-Z5T-W01 Key is a genuine OEM replacement designed for GX240, GX270, GX340, and GX390 horizontal shaft engines, as well as EM4000, EM5000, and EM6500 generators. As a direct Honda OEM part, it is manufactured to the exact specifications required for a proper fit in every unit it covers. Confirm your model and serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and this key may not apply to every production run of a given model.
Key Features
- Genuine Honda OEM Part — sourced directly from Honda, ensuring the correct profile and dimensions for the applications it covers, with no risk of the misalignment or slippage that an ill-fitting substitute can cause
- Broad Fitment — covers GX240, GX270, GX340, and GX390 horizontal shaft engines, plus EM4000, EM5000, and EM6500 generators; verify your serial number against the fitment table to confirm applicability
- Critical Drive Integrity — a correctly fitted key keeps the components it locks in precise rotational alignment; a worn, sheared, or missing key allows timing or drive components to slip, leading to hard starts, misfires, or mechanical damage
A key is a small, precisely dimensioned piece that seats in mating keyways machined into a shaft and the hub of a component mounted on that shaft — such as a flywheel or a pulley. It prevents the hub from rotating independently of the shaft, maintaining the exact angular relationship the engine or generator requires for correct timing and power transfer. When a key shears or wears, that relationship is lost, and the engine will run poorly, fail to start, or sustain internal damage until the key is replaced.
