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.

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.)

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.)

Bolt Pattern - Side

Measuring the distance (D) 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 Dexter Trailer Hubs and Drums 8-219-4UC3 Review

Today were going to review part number 8-219-4UC3. This is the Dexter Trailer Hub and Drum Assembly with an 8 on 6-1/2-inch bolt pattern for 1/2-inch studs. This trailer Hub and Drum Assembly will include your eight 1/2-inch cone seat lug nuts. It will include the inner bearing, part number 25580, it will include the outer bearing part number 14125A, it will include the grease seal which is a 2-1/8 inch diameter grease seal, and will also include the grease cap which goes over the hub right there. Now the bearing races are included also. They are already installed, pressed into the hub.

There is the outer, and when I spin this around youll be able to see the inner race right there. The application on this Hub and Drum Assembly will fit the 5200 to 7000-lb Dexter axles. It has a drum dimension of 12 inches by 2 inches wide. The stud diameter for the wheel studs is 1/2 inch. The bolt pattern is an 8 lug 6-1/2 inch pattern.

Now the capacity on this Hub and Drum assembly is 3500 lbs. So when this one is used with another Hub and Drum Assembly on the other side of the axle it will give you the max of 7000 lbs. I do want to give you a few dimensions. The bolt pattern which we mentioned is 8 lugs 6-1/2 inch. So basically the way you would measure that is on a Hub and Drum that has an even amount of lugs which in this case would be eight, you just take one or pick any of the studs and measure from the center of that to the one directly across from that.

So if you go from center to center it will be 6-1/2 inches and that will give you the 8 lug 6-1/2 inch bolt pattern. The other dimension I would want to give to you is the drum size. It is 12 inches. Thats the measurement of the inner of the drum. And then the width will be 2 inches.

So this Hub and Drum assembly will work with 12-inch by 2-inch brake assemblies. And that should do it for our review on part number 8-8-219-4UC3.

Most mobile home axles are built with an odd sized spindle that do not have any available hubs with a traditional trailer wheel bolt pattern. The only want to be sure is to either get the bearing numbers off the old bearings or to measure the spindle diameters with a dial or digital caliper, at least to the 1/100th. Bearing numbers is by far the easiest. Check out the link to the spindle below. There is a diagram that shows the measurements that you will need to take in order to positively determine whether or not a hub is available.

  • Can Existing Grease Lube Hub Assembly be Replaced With Oil Bath Lubrication
  • I would recommend that you install Trailer Hub & Drum Assembly, part # 8-219-9UC3, on your trailer. This hub is identical to the Trailer Hub & Drum Assembly, part # 8-219-4UC3, that you referenced except it is setup for oil bath bearings instead of grease bearing. These hubs have a 2-1/8 inch seal. The Oil Cap Kit, # RG04-270, is threaded and would only work on hubs that are threaded for screw in style caps. This would not work on the # 8-219-4UC3 as it takes press in style caps.

  • Hub and Drum Assembly Needed for a 1979 Featherlite Horse Trailer with 6000lb Axles
  • It sounds as if you will need the trailer hub and drum assembly # 42866UC3, which has an 8 on 6-1/2 bolt pattern and uses the # 25580 inner bearing (1.75 inch inner diameter) and # 14125A outer bearing (1.25 inch inner diameter). This assembly works with a 12 x 2 inch brake assembly like left hand electric brake assembly # 23-105, and with wheels that use 1/2 inch studs. There are numerous other possibilities, like 12 x 2-1/4 inch brake assemblies, different bearing part numbers, and diffe

  • How to Determine Which Replacement Hubs are Needed for a Kaufman Car Hauler
  • In order to determine which hub you will need for your Kaufman car hauler you will need to get some information from the hub of your trailer. The first thing you are going to need to do is remove the hub and give me the bearing numbers that are stamped on the inner and outer bearings of the hub. The next thing you will need to give me is the bolt pattern from the wheels/hubs you are replacing. You will also need to know what size studs are on your hubs. I attached an FAQ article on how to

  • How to Choose the Correct Brake Assemblies and Hubs and Drums for a 7000 lb AL-KO/Hayes Axle
  • We do have replacement AL-KO/Hayes brake assemblies for 7,000 lb axles, # 185100, for left side and # 185150 for the right. These are 12 inch by 2 inch electric brake assemblies that will mount to AL-KO/Hayes 4-bolt pattern or standard 5-bolt pattern brake mounting flanges. The way to determine what hub and drum you need is to remove the old hub and find the bearing and seal part numbers. These part numbers will be stamped into the metal of the bearings and most likely in the rubber of the gr

  • How to Correct for Extreme Stress and Bearing Damage on 5200-Lb Torsion Axle on Tandem Trailer
  • If your axle castle nuts are backing off and shearing the cotter pin then this extreme force could be coming from one or more possible causes. I suggest you check your rear axle tire treads for signs of uneven wear. If you notice more wear on the inside edges of the tires this could indicate any of several possible root causes, an overloaded axle, damaged axle or bent spindles. Any one of these conditions could result in wheel misalignment. This condition could in turn lead to excessive heat

  • What Size Wheel Center Hole Will Fit on Trailer Hub 8-219-4UC3
  • The pilot hole on a wheel would have to be 4.75 inches or larger. It can be larger because this hub uses lug nuts to secure and center the wheel on the hub (lugcentric). If it just had holes for wheel bolts (hubcentric) then the pilot hole would have to be exact.

  • How to Pick Out a Hub and Drum to Go to a Different Bolt Pattern
  • Yes, you can go to a hub with a different bolt pattern as long as you match everything up. You will need to make sure the bearing numbers are the same and that your brake assemblies are the same size. The Trailer Hub and Drum Assembly # 8-219-4UC3 that you referenced uses inner bearing number 25580, outer bearing number 14125A and is designed for 12 inch by 2 inch brake assemblies. You should note that going to a hub with a higher towing capacity does not necessarily give you more overall
