The Honda 91051-734-003 Needle Bearing (17X21X13) is a genuine OEM component designed for FR600 and FR800 tillers. As a direct Honda replacement, this bearing is sourced to the exact specification Honda calls out for these machines, giving you the right part from the first order. Confirm your tiller's serial number against the fitment table before ordering, as Honda supersedes bearings at specific production breaks — part number 91051-734-003 covers the serial ranges shown.
Key Features
- Genuine OEM Bearing Specification — sourced directly from Honda, ensuring the needle complement, inner diameter, outer diameter, and length match what Honda engineered into the FR600 and FR800 tiller drivetrains
- Exact Dimensional Fit — the 17×21×13 designation identifies bore, outer diameter, and width precisely; installing the correct size bearing prevents play, noise, and premature wear at the bearing journal
- Verified Tiller Fitment — listed for FR600 and FR800 tillers; check your serial number against the compatibility table to confirm this is the correct supersession for your unit
- Drivetrain Integrity — a worn or failed needle bearing causes roughness, vibration, and eventually seizure at the rotating assembly it supports, taking the tiller out of service mid-season
A needle bearing uses a ring of slim cylindrical rollers to support a rotating shaft under radial load while occupying minimal radial space. In a tiller like the FR600 and FR800, needle bearings appear at high-load points in the transmission and tine drive where a conventional ball bearing would be too large to package efficiently. When a needle bearing wears — through contamination, lubricant breakdown, or age — it develops play and generates heat, leading to shaft damage and loss of drive. Replacing this bearing at the first sign of roughness or noise protects the surrounding components and keeps the tiller working through the season.
