The Honda 91203-751-003 Oil Seal (20X38X10) is a genuine OEM component designed for the H3011 and H3013 riding mowers and the H4013 lawn tractor. As a direct Honda OEM part, it meets the same specifications as the original seal installed at the factory. Verify your unit's serial number against the fitment table before ordering, as Honda supersedes seals at production breaks across this equipment lineup.
Key Features
- Genuine Honda OEM Seal — sourced directly from Honda, this seal matches the original in dimensional specification (20 x 38 x 10 mm), ensuring the correct interference fit in its bore
- Oil Retention Performance — a properly functioning oil seal prevents lubricant loss and keeps contaminants from entering the sealed interface; a worn or damaged seal leads to oil leaks and accelerated component wear
- Confirmed Fitment — listed for H3011 and H3013 riding mowers and the H4013 lawn tractor; always cross-reference your serial number with the fitment table to confirm the correct part for your production range
An oil seal creates a dynamic barrier between a rotating shaft and a stationary housing, holding lubricant in place while blocking dirt, moisture, and debris from entering. In Honda riding mowers and lawn tractors, oil seals are used wherever a rotating component — such as a driveshaft or axle — exits a gearcase or housing. When an oil seal deteriorates, it allows oil to escape and contaminants to enter, which can cause rapid wear to bearings and other internal components and lead to more significant mechanical damage if not addressed promptly.
