1971 Honda CB350K3 · Rear Bearing Retainer & Tool Buying guide
The retainer is the replacement wheel part; the four-pin tool is workshop equipment. Its 22mm hex and 3/8-inch square drive offer two ways to turn it with suitable hand tools.
The replacement ring references 41231-286-000, the K3 rear bearing retainer. Honda shows it on the sprocket side of the drum-brake rear hub. If a different wheel has been installed, identify its retaining arrangement instead of assuming the K3 frame determines the required ring.
The listed tool is designed for retaining rings in this reference family and provides a 22mm hex plus a 3/8-inch square drive. Compare its engagement with your ring before use. Follow the correct workshop procedure rather than striking or improvising against a damaged retainer.
No. The tool and retaining ring are separate products. Order the tool for service access and add the replacement ring if inspection shows that the existing retainer needs replacement.
The original K3 has a rear drum brake. Honda shows the 41231-286-000 bearing retainer on the sprocket side of that hub, so use the exact ring reference and hub arrangement to identify it.
It has a 22mm hex and a 3/8-inch square drive. Choose suitable hand tools and follow the workshop procedure for the fitted wheel; the drive sizes are not a torque specification.
