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"

Let me get that taken care of for you Kell. I am sorry that happened. You should hear from us shortly.



by:

The rating is for etrailer, not the product. The Dexter hub and drum assembly was fine, etrailers way of doing business is not. The estimated ship date kept changing due to a "location in warehouse" issue. It took 2 weeks before they shipped it out. Bottom line, if you need something in a timely fashion, look elsewhere.



by:

Everything arrived in a timely manner. However one of the bearings was damaged half of the Lugnuts were missing because the box that was shipped in was destroyed by the time it got to me. Didn’t have time to deal with having new stuff sent I was able to get a new bearing locally other than that fit was good

  • Is Dexter Hub Drum Assembly # 8-430-5UC3 Available in Individual Parts?
    The Dexter Trailer Hub Drum Assembly - 9K to 10K - 8 on 6.5 - Oil Bath - Non-ABS Drum - After July 2009 # 8-430-5UC3 comes as the complete kit and the hub/drum is not available separately.

  • Determining the Weight Capacity of Axles and If Hubs Are Available
    Unfortunately we don't carry hubs above 10K. The largest hubs we carry are 9K-10K Dexter Hub and Drum Assemblies # 8-430-5UC3. I have no way of knowing what hubs may work on your trailer unless you measure the spindles using a digital caliper like # PTW80157. I've attached a photo to assist with the locations. These measurements will possibly help to determine the capacity of your axle, but any hubs that may fit will limit your axle capacity to the max capacity of the hubs.

  • How To Find Correct Replacement Hubs/Drums for Dovetail Gooseneck with Dexter Dually Axles
    It's very likely you have a Dexter 9K or 10K General Duty Axle therefore for a replacement hub/drum you're looking at the Dexter Trailer Hub and Drum Assembly for 9K to 10K Axles part # K08-288-90 or part # 8-430-5UC3. These are both oil bath hubs with an 8 on 6-1/2" bolt pattern. In order to confirm you'll have to crawl under the trailer and read the axle tag to see what brand/capacity they are as well as the date of mfg.

  • Timbren Axle-Less Trailer Suspension System w/ Electric Brake Hubs to Replace 2800 lbs Dexter Axle
    Thanks for the pictures, they were very helpful. I have a great solution for you but no, they do not make one piece axle and brake assemblies that will fit your spring spacing. I recommend the Timbren Axle-Less Trailer Suspension System w Electric Brake Hubs item # A35RD545E. The individual suspension units replace your existing axle and operate independently. The 4" drop spindle should match up with your existing axle and provide the same ride height. They will fit any frame width and...

  • Determining Replacement Hub And Bearings For Dexter P-12 SLR Trailer Axle
    I can definitely help you find the correct replacement hub and bearings for your Dexter P-12 SLR axle, but since part of the serial number was unreadable you will need to take a few simple steps to identify which bearings your axle uses. The easiest way to accomplish this is to remove one hub and look for the numbers stamped on the inner and outer bearing like shown in the attached picture of the # L44649. If your bearings are too worn to be able to read the numbers, you will need digital...

  • Replacement Hub/Drums and Brake Assemblies for Dexter 10k Trailer Axle
    Since your trailer has Dexter 10k axles the correct hub/drum you need is the part # 8-430-5UC3 which comes with bearings, races and seal. Since you need shoes and magnets it would be easiest to go with new assemblies altogether like with the part # 23-438-439. Otherwise for shoes you'd need the part # BP04-325 for the left hand side and # BP04-335 for the right hand side. Then for a replacement magnet # BP01-301.

  • Replacement Hub and Drum for Dexter 10K Axles with 008-214-05 Hubs
    The hub you need is # 8-214-5UC1. Since it is separate from the drum you would not need to replace both unless it is time to replace the drum as well if it is worn or damage. If it is then the drum part is # 9-27-1. We also have the mounting bolt for this hub assembly, # 7-103.

  • Electric Drum Brake and Hub/Drum for 10K Axle
    I linked our main page for all electric drum brakes rated for a 10K axle. These are all 12-1/4-inch diameter but vary in width; 3-1/2-, 3-3/8- and 4-inch widths are available. We have these in both manual-adjust and self-adjust types. For example, part # AKEBRK-10 is a high-value pair of self-adjusting left- and right-hand brakes in the 12-1/4 x 3-3/8 inch size which fits wheels 15-inches in diameter and larger. These brakes use a 7-bolt mounting pattern. We do offer a 10K oil bath type...

  • Hub and Electric Brakes for Dexter SLR D90 9000-lb-Rated Axle
    Thank you for the photo of the brake assembly from your Dexter SLR D-90 9K axle. The correct hub you need for your Dexter D-90 axle is the part # 8-430-5UC3 which includes bearings, races, oil seal, oil cap, wheel bolts, and lug nuts. With this hub you can use Kodiak Synthetic Bearing Oil # XLPROLUBE. For brake assemblies you can use part # 23-451 for the right side brakes and part # 23-450 for the left side.

  • Correct Replacement for Dexter Hub/Drum 8-415
    I was able to cross reference the Dexter Hub/Drum 8-415 to the Dexter Trailer Hub Drum Assembly part # 8-430-5UC3 which should be an exact replacement. I don't have any depth measurements of the above/drum but what you would need to measure to confirm is the inside of the contact surface on the hub where the shoe rides and this should measure 12-1/4" x 3-3/8". If so, you should be good to go. In regards to braking assemblies, the best option we have is the Dexter Brake Kit part # 23-450-451...

  • Replacement Brake Assemblies for Dexter 10k Axles on Gatormade Trailer
    We have what you need! Thanks for the photos. Even though the serial number is torn from the axle tag, we still identified the brakes you need with the Unique ID Number 124394998016 from your 10k Dexter axle tag. I confirmed with my tech at Dexter that you need the Dexter Electric Trailer Brake Assembly - Self-Adjusting - 12-1/4" # 23-450 (left side) and the # 23-451 (right side). These are direct replacements of brakes constructed for your 10k Dexter axles on your Gatormade trailer.

  • Will Dexter 9K - 10K Hub and Drum Fit Lippert 10K Axle
    Hub and drum assemblies, like the Dexter # 8-430-5UC3 you referenced, are universal so they typically fit any 9K - 10K axle just fine. With that being said, there are some exceptions out there so you just need to confirm that your axle uses a # 387A inner bearing, a # 25580 outer bearing, and that the inner diameter of your grease seal is 2.875" to ensure that this fits. Pull your current hub and check the numbers on your bearings to confirm this. If you can't find the numbers then Lippert...

  • Replacement Wheel Studs for Dexter P-12 D90 Axle
    Thanks for the photo. It gives me the further information needed to assist. The P-12 only gives the factory location from Dexter. The D-90 model is a huge help as it designates is a 9k axle. The correct hubs you would need for your Dexter D-90 axle is the part # 8-430-5UC3. Then the wheel stud replacements are # 7-223 for a 2 inch length or # 7-257 for a 2-1/2 inch length.

  • Hub and Drum Assembly with 8 on 6-1/2 Bolt Pattern for Dexter 10,000 Pound Trailer Axle
    The Dexter 8-427 hub is no longer available. Even looking through Dexter's site the only references to it are replacement bearings. You can use a wheel with a larger pilot hole as long as the wheel attaches to the hub using lug nuts and not bolts. Hub and drum assembly # 8-430-5UC3 uses lug nuts to secure the wheel to the hub and uses inner bearing 387A and outer bearing 25580.

  • 10k Dexter Replacement Hub for a 8-415
    I did some checking and the hub/drum we offer that will work for you is the part # 8-430-5UC3. This uses the same bearings as the 8-415 and will be an exact fit aside from the fact this is a non-ABS setup and the 8-415 came in an ABS setup and non-ABS setup. The part number for the ABS version is part # 8-430-7 which we do not carry at this time.

  • Difference Between Dexter 008-430-05 and 8-430-5UC3
    The Dexter # 8-430-5UC3 and 008-430-05 are the same hub and drum assembly. They use the same bearings and seals, the same oil cap kit, have the same capacity, and fit axles manufactured after 2009. The only difference between the part numbers is that the # 8-430-5UC3 is the full kit that comes with everything. The bearings, races, oil seal, and oil cap kit are all included. The 008-430-05 does not include these, or in some cases comes with only the bearings and races.

  • Availability of Spindle and Hubs for 10,000 lb Trailer Axle
    As you may have noticed, the highest capacity spindle we carry is for a 7,000 lb axle, # TRU37FR. Your best bet is to source the spindles for a 10,000 lb axle through a local trailer shop or dealer. If are able to source the spindles, we do have hubs for 10,000 lb axles. I'll list them below: # 8-430-5UC3 - Dexter Hub Drum for 9K to 10K axles manufactured after July 2009 (for non ABS brakes) - uses inner bearing # 387A, outer bearing # 25580 and oil seal # 10-51 # K08-288-90 - Dexter...

  • When is Wheel Retainer Ring Needed for Dexter Hubs and Wheels
    The wheel retainer ring that is included in certain hub assemblies like the Dexter # 8-430-5UC3 that you referenced will be installed on dual wheels when tapered coned lug nuts like # 6-109 are used instead of flange wheel nuts. It essentially allows you to use a lower torque spec for the nuts which would be required when using coned nuts.

  • Why Are There Different Brake Drums for 9,000 and 10,000 lb Axles After July 1, 2009?
    The Dexter Trailer Hub/Drum Assembly # 8-430-5UC3 is a one piece assembly, hub and drum together. It fits Dexter 9k and 10k general duty axles made after 07/01/2009. Hub # 8-288-3UC1 is a 2 piece for 9K axle (after 10/89) and 10K axle (through 7/1/09). It does not come with the drum or mounting bolts. Dexter changed their spindle diameters on these two capacity (9,000 and 10,000 lb) axles. The biggest difference was in the inner diameter of the seal needed.

  • What is the Capacity of a Dexter P-12 Model D100 Axle
    It looks like you're likely trying to replace your hubs/drums on your Dexter axle and I do believe that the "0100" you found on the spec plate actually reads "D100" since that was one of the models that Dexter had for this particular line of axles; I've confirmed this with Dexter as well. These axles were 10k axles and they came in both a general duty and a heavy duty model with the 10k capacity. In order to find out which hub/drum will work as a replacement, you'll need to pull the hubs...
