1978 Honda CB750F · Wheel Seals & Hub Parts Buying guide
Identify the wheel assembly before ordering hub parts. The front and rear seal kits have different applications, while the rear bearing retainers must be matched to their position and replacement reference.

The offered front bearing is 6302-2RS; its listing says two are used per front wheel and to order the quantity needed. The rear selection includes 6305-2RS, replacing 96140-63050-10. A separate 6304-2RS product also lists this model, so identify each position in the fitted rear assembly before deciding the replacement order.
The 6304-2RS product is sold individually and states two per rear wheel. That supplier usage note does not map the separate 6305 bearing position. Use the fitted hub’s service information and original bearing numbers to establish the combination.
Retainer 73-1068 replaces 41231-286-000 on the brake-disc side. Retainer 28-4015 replaces 41231-283-000 on the sprocket side. Match the position and reference rather than treating their shared rear-wheel description as interchangeability.
Tool 35-9129 explicitly lists retainers 41231-286-000 and 41231-429-000, with a 22 mm hex and 3/8-inch square drive. Its stated coverage does not include the selected sprocket-side reference 41231-283-000. Confirm the tool for that ring separately.
