Review of Dexter Trailer Hubs and Drums 42866UC3


Today were going to review part number 42866UC3. This is the Dexter Trailer Hub and Drum Assembly 8 on 6-1/2-inch bolt pattern. This trailer Hub and Drum Assembly will include the eight 1/2-inch cone seat lug nuts. It will include the inner bearing, part number 25580, the outer bearing part number 14125A, it will include the 2-1/4 grease seal and the grease cap. The races, the bearing races are also included and they will be actually preinstalled into the hub. The outer race would be right here.

The inner race would be right in there. All of our Hub and Drum Assemblies will come with the races preinstalled. The application for this Hub and Drum Assembly is for most 5200 to 7000-lb Dexter axles with spindles that will require either a 2-1/8 inch grease seal or a 2-1/4 inch inside diameter grease seal. The drum dimension is 12 inches diameter by 2 inches wide. The bolt pattern is an 8 on 6-1/2 inch bolt pattern.

The stud diameter is 1/2 inch. This Hub and Drum Assembly will fit on spindles that are either 2-1/8 or 2-1/4. It does come with the 2-1/4 inch inside diameter grease seal. If you do need the 2-1/8 seal you will need to use part number 10-1. The capacity on this assembly is 3500 lbs.

So when this is used with another assembly on the other side it will give you the maximum capacity of 7000 lbs. Now just a couple dimensions. The bolt pattern is an 8 on 6-1/2 inch which means eight lugs, 6-1/2 inch diameter and basically the way to measure that usually on a bolt pattern that is an even number of lugs like in this case eight. You just measure directly across from the center of one to the center of the other. Thats 6-1/2 but its hard to do because of this higher hub in the middle.

So if you just measure from a one wheel stud next to the other wheel stud and if it measures 2-1/2 inches that would also mean its an 8 on 6-1/2 inch bolt pattern. The other dimension would be the drum dimension which is 12-inch diameter and 2 inches wide. So 12-inch diameter on the inside would be 12 inches, the diameter is 2 inches. And that should do it for our review on part number 42866UC3.
