The Honda 91201-ZA0-003 Oil Seal (33X48X7) is a genuine OEM sealing component designed for a wide range of Honda equipment, including GX360 horizontal shaft engines, EL5000, ES6500, and EX5500 generators, EV4010, EV6010, and EVD4010 RV generators, and H4514, HT3813, and HT4213 lawn tractors. As a direct Honda OEM part, this oil seal is manufactured to the exact dimensions and material specification Honda requires — 33 mm inner diameter, 48 mm outer diameter, and 7 mm width — ensuring a proper fit without guesswork. Confirm your machine's serial number against the fitment table before ordering, as Honda updates seal specifications at production breaks across these models.
Key Features
- Genuine OEM Sealing Integrity — manufactured by Honda to the precise 33×48×7 mm dimensional spec, delivering the lip geometry and sealing force the original design requires
- Broad Cross-Equipment Fitment — listed for GX360 engines, EL5000, ES6500, and EX5500 generators, EV-series RV generators, and H4514, HT3813, and HT4213 lawn tractors, covering a wide range of Honda equipment classes
- Variant Verification Recommended — because this seal is listed across multiple equipment types and production runs, match your machine's serial number to the fitment table to confirm this is the correct seal for your specific unit
- Prevents Oil Loss — a functioning oil seal keeps lubricant in and contaminants out; a failed or hardened seal leads to oil leaks that accelerate internal wear and can cause equipment shutdown
An oil seal creates a dynamic barrier around a rotating shaft, keeping engine or gearbox oil contained within the housing while preventing dirt, dust, and moisture from entering. The seal's flexible lip presses against the rotating shaft surface; over time, heat cycling and wear can cause the lip to harden or deform, allowing oil to bypass and leak externally. Replacing a worn oil seal with the correct OEM part — matched precisely to the shaft and bore dimensions — restores a leak-free barrier and protects the internal components of the engine, generator, or tractor from contamination and oil starvation.
