Today were going to review part number 8-174-5UC3. This is the Dexter Trailer Hub and Drum Assembly
for a 5-spoke utility application. This Hub and Drum Assembly will be used on Dexter 6000-lb
and 7000-lb axles or on spindles requiring a 2-1/8-inch or 2-1/4 inch inside diameter
grease seal. The capacity on this assembly is 3500 lbs each which means when used with
another one on the other side of the axle would give you your maximum of 7000 lbs. The
drum size is a 12-inch diameter by 2-inch wide. Included with this assembly are the
bearing for the inner, part number 25580, for the outer bearing would be 15123, the
seal included would be part number 10-1 which is the 2-1/8 inch inside diameter seal and
the grease cap that goes on the end of the hub.
Now the bearing races will be also included but they will already be preinstalled into
the hub. The outer race would be located right here. The inner race is located right there.
All of our Hub and Drum Assemblies will come with the bearing races preinstalled, pressed
in. Now this Hub and Drum Assembly is different from most because it is designed with a 5-spoke
utility bolt pattern.
