Key Features
- Genuine OEM Sealing Integrity — manufactured to Honda's exact dimensions and material spec, ensuring a proper seal where an ill-fitting substitute could allow fluid or contaminant intrusion
- Direct OEM Replacement — listed under part number 90872-752-801 and engineered to install without modification into CD3813, HT3810, and HT3813 lawn tractors
- Serial Number Verification Advised — Honda updates parts at production breaks, so match your tractor's serial number to the fitment table to confirm this is the correct plug for your unit
A sealing plug closes off a machined port or passage in the tractor's housing, preventing fluid leakage or contamination ingress at that location. The 40X6 designation identifies the specific dimensional profile of this plug, which is what determines whether it seats correctly and forms a reliable seal. When a sealing plug is missing, damaged, or replaced with an incorrect size, the opening it covers is left exposed — leading to fluid loss, contamination, or pressure loss in the surrounding system depending on where it is installed.
