Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.

Measuring Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)

Measuring Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)

Measuring Bolt Pattern - Side-to-Side

Measuring the distance from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Video Transcript for Review of Dexter Trailer Hubs and Drums - Hub and Drum - 8-393-6UC3-A

Today we're going to take a look at the Dexter trailer hub and drum assembly for 7200 pound axles, with the eight on 6-1/2" bolt pattern, and the 5/8" diameter studs. How this hub and drum assembly will fit most 7200 pound axles, that are manufactured after 1999, with the four-bolt brake flange.Now before 1999, the 7200 pound axles used a nine-bolt brake flange, and the hub and drum assemblies will not interchange between the older nine-bolt and the newer four-bolt brake flanges.This trailer hub and drum assembly provides the surface area, let me turn it around here, for your brake shoes to grip when the brake is activated. It's compatible with electric, right here, or hydraulic drum brakes. It's a sturdy iron construction. The bearings, the races, grease seal, grease cap, wheel bolts, lug nuts are all included. This hub and drum is made in the U.S.A.Again, the application is 7200 pound trailer axles manufactured after 1999, that use the four-bolt brake flange.

The drum dimensions on this, which is always measured on the inside here. The diameter Which would be this inside to this inside, 12-1/4". The width, which will be measured from here out to here, is 2-1/2" wide. It is designed to work with a 12-1/4" diameter brake assembly.The wheel size that will fit on this, is going to be 16" to 17-1/2" diameter. The bolt pattern is an eight on 6-1/2" bolt pattern.

The wheel lug size this uses is a 5/8" flange nut, you can see it includes eight of those. It's part number 95188.The bearings are included. The inner bearing, which is the larger of the two, is part number 25580. And that's designed to go right back here. The outer bearing, which is the smaller, part number 02475, that'll go right out here.

Now the bearing races are already pre-installed, both outer and inner.The grease seal, which is included right here, is a double-lip grease seal. It's part number 10-36. Then the last is the grease cap. The grease cap is a 2.72 overall diameter, and it's part number 38605.But that should do it for the review on the Dexter trailer hub and drum assembly, for 7200 pound axles. Eight on 6-1/2" bolt pattern, and 5/8" diameter studs..
