The Honda 91204-187-013 Oil Seal (20X30X5) is a genuine OEM replacement designed for H3011 and H3013 riding mowers and H4514 and H4518 lawn tractors. As a direct Honda OEM part, it is manufactured to the same exacting standards as the original component your machine left the factory with, ensuring a correct fit without modification. Confirm your machine's serial number against the fitment table before ordering, as Honda updates seals at specific production breaks.
Key Features
- Genuine Honda OEM Seal — sourced directly from Honda, this oil seal meets the original dimensional and performance specifications for the 91204-187-013 application, maintaining the sealing integrity the drivetrain depends on.
- Correct Dimensions for a Drop-In Fit — the 20×30×5 mm sizing matches the original bore and shaft exactly, so this part installs into the same bore as the part it replaces without rework.
- Broad Fitment Across Honda's Tractor Range — listed for H3011 and H3013 riding mowers and H4514 and H4518 lawn tractors, covering a wide span of Honda's residential tractor lineup.
- Serial Number Check Recommended — Honda introduces running production changes, so verify your machine's serial number against the fitment chart to confirm this is the correct seal for your specific unit.
- Prevents Oil Loss and Drivetrain Contamination — a worn or degraded seal allows oil to escape the sealed cavity and permits dirt and moisture to enter, accelerating wear on surrounding components and reducing overall drivetrain life.
An oil seal creates a dynamic barrier between a rotating shaft and its housing, keeping lubricating oil contained within the sealed cavity while blocking contaminants from entering from outside. On Honda riding mowers and lawn tractors, a failed seal leads to oil leakage, lubricant starvation, and accelerated wear on the shaft and bearings it is meant to protect. Replacing a leaking or hardened seal promptly restores proper lubrication and helps prevent more costly drivetrain damage downstream.
