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"

Recieved the parts in a timely manner. They are large heavy items and do move around the shipping box, however no damage occured. Had to purchase the nuts & lock washers to attach the backing plate to the axle. Other than that everything was included. I used a double10Ga. wire. Brakes went on like a dream......my wife greased the bearings so that is probably why. Immediately left Michigan for Florida with a farm tractor on the trailor, checked the hub temp at every stop and experanced no problems. "Great Stuff" Sorry no pics. 209058

I drove my empty two axle car trailer a few times to break in the new brakes. During assembly I did not adjust the brakes tight enough, therefore the brakes would not lock up when empty. Adjusting the brakes manually is a royal pain because of the drop axle, so I let them self adjust. On my first 150 mile drive trailering a 66 Mustang, the brakes self adjusted perfectly! Great product! 800211

    Thank you for that info and I definitely recommend replacing your boat trailer's brakes and we have exactly what you need. Based on the Dexter 8-247 number you gave we know you have a 3,500 lb Dexter 10" Hub and Drum Assembly such as part # 84546UC3. For a hub and drum that size the best option is the Hydraulic Trailer Brake - Dacromet because they are designed for marine applications with their corrosion-resistant dacromet coating and mount to a 4-bolt mounting flange such as # 4-35....

  • Brake Assembly Kit and Drum Recommendation
    So we are sure of fit, let's start with confirming your hub and drums fit your spindles before we look at the brakes. If those don't line up, we can't be sure you need a 10" drum to work with the # 23-26 and # 23-27 brake assemblies. For a 2,500lb axle like yours, we only have idler hubs so we won't have the hubs for you to install brakes but you will need to be sure of sizes before you buy brakes overall. To determine correct replacement hub size, you have to first determine which...

  • Replacement Axle with Electric Brakes for 6x14 Carry-On Trailer
    Your axle 3K8874 is rated for 3500-lbs. To find a suitable 3500-lb replacement axle that comes equipped with electric brakes, which is definitely the way to go, you'll just want to confirm two dimensions, the hub face spacing and the spring center spacing. Both dimensions are shown in the linked diagram as A and B. If your respective dimensions are 89-inches and 74-inches (which is likely) you can use Dexter axle kit # 35545E-ST-EZ-89 which includes the axle beam, brakes, hub/drums bearings,...

  • Replacement for UFP HD1377 Trailer Hub/Drum

These hub/drums both use a L68149 (1.378" inner diameter) inner bearing and a L44649 (1.063" inner diameter) outer bearing.

  • Hydraulic Drum Brake Assembly Recommendation for Dexter Hubs # 8-247
    The 8-247 Dexter hub that you have is our part number # 84546UC3 which has drum dimensions of 10 inch diameter by 2-1/4 inches wide. That means that the Hydraulic Brake Assembly Set part # AKFBBRK-35-D that you mentioned will fit and work well. 45 to 50 lbs is the recommended torque rating for the 4 bolts that hold 10 inch brake assemblies like these.

  • Replacing Dexter 008-249-07 Hubs with Hubs that Have 5 on 4-1/2 Inch Bolt Pattern
    I have good news! The 008-249-07 number you found indicates that your Tentrax trailer is equipped with Dexter hubs that use the # L68149 inner bearing and the # L44649 outer bearing. With this in mind you can easily replace the existing hubs with a set that features a much more common 5 on 4-1/2 inch bolt pattern. For this I recommend the Dexter Trailer Hub and Drum Assembly # 84546UC3. This is essentially the same hub that you have but with a 5 on 4-1/2 inch bolt pattern. The bearings,...

    Your Lippert 3,500 pound axle likely uses inner bearing # L68149 and outer bearing # L44649 and a 10-19 seal # RG06-050 which means that the correct hub would be the part # 84546UC3. You can remove your hub to verify this if you like, but if you do have a Lippert 3,500 lb axle this hub would work for you.

  • Will Adding Trailer Brakes to One Axle of a Trailer Make the Wheels Stick Out Further
    Installing brakes on one axle will not make the wheels stick out any further than the idler axle.

I attached a help article that will walk you through the process of adding brakes to your trailer for you to check out.

    The hub center's outer diameter of the Dexter Hub and Drum # 84546UC3 measures 2.59 inches. A rim with a 3.19 pilot diameter, like # AM20352 will fit onto the Dexter hub because the wheel is lug-centric and not hub-centric.

  • Parts Needed to Install Trailer Brakes on a Load Rite Trailer Model UT6512
    Looks like your Load Rite trailer UT6512 has a 3,500 lb axle. Most likely it's a standard 3,500 lb trailer axle but first you have to check to see if the axle has brake mounting flanges. If you can get back to me with whether or not you have brake flanges and the brand of your axle (most likely Lippert or Dexter) I can see which kit we have that may work.

The only way to be sure is to check the bearing part numbers and seal part number, but with a 3,500 lbs Dexter axle that has brake mounting flanges you will most likely have the # L44649 Outer and # L68149 inner bearings and # 58846 seal.

    If nothing is noted on the axle or outside of the brakes for the front or rear, you can remove the front hub and take a look at the brakes. The magnet is always on the bottom of the assembly and the actuating arm for the brakes always bows toward the front of the trailer. The larger brake shoe is on the front of the brake assembly also.

  • Can 10 inch Brake Drums be Used with 13 inch Trailer Wheels
    There are exceptions to some rules, generally speaking 13 inch trailer wheels will not work with 10 inch hub and drums.

Dexter Hub/Drum # 84546UC3 has 1/2-inch studs and coned lug nuts. If used with a 15- or 16-inch steel wheel the torque range is 90-120-ft-lbs.

    A trailer hub and brake drum should be able to be removed by just sliding off the spindle after the castle nut is removed. The castle nut is located underneath the grease cap.
