The Honda 44328-952-000 Pinion Gear Bush is a genuine OEM replacement designed for HR21 lawn mowers and HT3810, HT3813, and HT4213 lawn tractors. As a Honda OEM component, this bush is made to the same specification as the original part it replaces, ensuring a direct, accurate fit in the drive assembly. Honda supersedes parts at serial number breaks, so confirm your machine's serial number against the fitment table before ordering. This part is a like-for-like replacement for worn or damaged originals, keeping the drive train operating as Honda intended.
Key Features
- Genuine OEM Fit — sourced directly from Honda, this bush matches the original in every dimension, so installation is straightforward with no guesswork on tolerances or sizing
- Drive Integrity — a worn or damaged pinion gear bush allows excessive play in the gear assembly, leading to uneven power transfer, accelerated gear wear, and rough or inconsistent drive engagement
- Broad Fitment — covers the HR21 lawn mower and HT3810, HT3813, and HT4213 lawn tractors; verify your serial number against the fitment table to confirm the correct part for your specific unit
The Pinion Gear Bush is a precision-fit bushing that supports and centers the pinion gear within the drive assembly of the mower or tractor. It provides the bearing surface that keeps the gear running true, absorbing side loads and reducing metal-to-metal contact between the gear shaft and its housing. When this bush wears, the pinion gear develops unwanted play, which accelerates wear on the surrounding gear teeth, produces vibration, and can cause the drive to slip or fail to engage cleanly.
