Star Hubs 1940-1966 with Tapered Roller Bearings

These replacement parts fit aftermarket type 1940-1966 Star hubs with non-standard wheel bearings.

For Star hubs, Springer rockers, seat posts and many other applications. Sold each.

On star hubs the brake drum is fixed by five lug bolts to the hub flange. The brake drum must not touch the spoke flange on the hub. The cast brake drums will break — especially when it is distorted by tightening the bolts. Manufacturing tolerances (aftermarket brake drums and hubs) can cause the drum to touch the hub. Before you tighten down the lug bolts, you will want to check for sufficient brake-drum to spoke flange gap and — if not present — use one of these shims.

Star hub reproductions that are equipped with tapered roller bearings require an uniform 11/16” axle center part. Harley Davidson axles for Star hubs (all Knuckles and Pans, SV Big Twins 1937-1966, 750 twins 1937-1951 rear, 1966 Shovels) have a center part with only the first 1-1/4” measuring 11/16” while the rest is reduced in diameter. On this reduced diameter a 11/16” Timken bearing will not fit, of course. On the other hand, a uniform diameter goes very well alongside with OEM star hub bearing sleeves, as these sleeves only touch the axle on their initial 3/4”. (The other side is borne by the brake side spacer.) Slight modifications may be required if you notice excessive wheel sideplay.

If you often ride your classic scooter on long distances you might prefer wheels with modern, low maintenance bearings. Hence these complete, ready-to-install wheel assemblies work as stock replacements but feature an upgraded hub with modern tapered roller wheel bearings. The hubs accept all stock drum brakes.
