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"

by:

These Dexter trailer hub and drum assemblies fit perfectly, just like the OEM one's I am replacing. Original brakes lasted over 10 years and 26K miles (with life still left on the brake shoes)!



by:

The product from etrailer was easy to order, came on a timely basis and fit perfectly. I happily will use etrailer again for my future needs.



by:

Promptly shipped and received. Minor problem, the bearings, nuts, dust cover and seal were all just thrown loose in the box with the hub resulting in the seal being bent and unuseable. No big deal. Otherwise great service.

Thanks etrailer.

what drum and hub assy do i need to convert my house tralier axles to use regular tires and wheels? im having trouble finding tires for them. bearing, outside 1.25, inside 1.75, 2 brake drum, 5 or 6 holes wheel.

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.


by:

etrailer.com is the best online company I have found to buy quality trailer parts. This Dexter part is high quality. You can depend on Dexter quality. etrailer shipped my order immediately.

  • Trailer Hub and Wheels for Inner Bearing 25580 and Outer Bearing 14125A
    We have hubs that have a seal and bearings that are very close to the measurements you gave. The closest are Grease Seal # GS-2250DL, which has a 2.25" inner diameter, Inner Bearing # 25580, which has a 1.75" inner diameter, and Outer Bearing # 14125A, which has a 1.25" inner diameter. For that you will need Dexter Trailer Idler Hub Assembly - 5,200-lb, 6,000-lb and 7,000-lb Axles - 12" - 8 on 6-1/2 # 42865-KIT for an idler hub or Dexter Trailer Hub and Drum Assembly for 5,200-lb to 7,000-lb...

  • 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...

  • Tightness Recommendation for Castle Nut on Trailer Hub
    I'd go on the tighter side of what you mentioned where there's no play yet you can still spin the wheel several times on one push. You might put your hand on the hub to feel if it's getting overly warm next trip you take but I believe that's the best spot you'll have.

  • Selecting Correct Bearing Buddy for 8-Lug Hub on 7000-lb Axle on PJ Dump Trailer
    Selecting the correct Bearing Buddy bearing protector for your 8-lug hubs requires that you know the hub's bore where the grease cap (or Bearing Buddy) fits. This requires using a precision digital or dial caliper and measurement to the nearest thousandth - 3 decimal points. You also want to note whether you hubs are threaded or non-threaded as we offer both types of Bearing Buddy. For example, we offer an 8-lug hub for 7K axles, part # 8-219-4UC3, and this hub's bore happens to be 2.720-inches...

  • 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...

  • How to Choose the Correct Replacement Hubs and Brakes for Keystone Montana Fifth Wheel
    Thank you for the information you provided. Based on the sticker on the brakes I can tell you that the replacement brakes you need are the Dexter Electric Trailer Brake Assembly - 12" - Right Hand # 23-106 and Left Hand # 23-105. The brakes are for 6,000 lb axles so based on that and the 8-219 you provided I was able to narrow down what hub you need, but there is still a bit more info to get the correct part - the bearings and wheel bolt pattern. For example, the Dexter Trailer Hub and...

  • Replacement Axle Recommendation for a Mobile Home Trailer
    Mobile home axles are designed for one time use and because of that we don't offer replacement hubs that will fit them since the spindles are usually very unique. Best option would be to go with a new axle. I attached a page that has all of the replacement axles we offer. You would want to go with the ones that are the closest in dimension and weight capacity as what you currently have/need.

  • Comparing Dexter K08-219-90 and K08-219-9B Hub and Drum Assemblies
    The only difference between the # 42866UC3 and # 8-219-4UC3 is the grease seal. The # 8-219-4UC3 uses a # GS-2125DL grease seal with an inner diameter of 2.125" and outer diameter of 3.376". The # 42866UC3 uses a # GS-2250DL grease seal with a larger 2.25" inner diameter.

  • Determining the Right Brake Assembly and Hub Drum H and H Cargo Trailer
    To get the correct brake assembly, you need to know the axle weight capacity, the backing plate bolt pattern, and the dimension of the drum. A 7000 lb axle would typically use a 12 x 2 assembly with a 5 bolt backing plate. Parts # 23-464 and # 23-465 are a good example. For replacement drums, we would need to know the wheel bolt pattern (which is typically 8 on 6-1/2) and the reference numbers off of the existing wheel bearings. Part # 8-219-4UC3 would be a typical hub and drum for a 7000...

    From what I have found, the ALKO hub and drum assembly you have is for 7,000 lb axles. I believe the Dexter Trailer Hub and Drum Assembly for 5,200-lb to 7,000-lb Axles - 12" - 8 on 6-1/2 # 8-219-4UC3 will work as a replacement. This has the same bolt pattern and uses the same outer bearing you have now with an inner diameter of 1.25". Your 21334TB grease seal has an inner diameter of 2.125" so that also matches the grease seal that comes with this assembly. The only piece of information...

  • Proper Way to Tighten Trailer Spindle of Castle Nut
    After you've packed the bearings and assembled everything, carefully slide the hub assembly onto the spindle and install the outer bearing. Install the spindle and tang washer and run the spindle nut down finger tight, then rotate the hub back and forth then rock the hub side to side to make sure everything is seated properly. This will have had provided more room on the spindle, so run down the spindle nut with your fingers a bit more. The hub should spin freely, with a bit of brake lining...

  • Should Trailer Bearings Spin on the Spindle they are Installed On
    When installed properly the portion of the bearing that attaches to the spindle should not spin. Only the outer portion should be spinning. It's pretty easy to overtighten a spindle nut since they don't have to be very tight so that would be the most likely situation. When our installers replace a trailer hub, there isn't a set torque spec used when tightening the spindle nut. The hub is placed on the spindle, making sure the inner and outer bearings are correctly seated. The spindle...

    The part # 8-219-4UC3 is a hub/drum but for a hub without the drum that would fit the same spindle you would want the part # 8-231-50 and then would need to provide the seal part # RG06-090 as it does not come with seals and this is the same as what you need.

While that is most of the information needed, you also need to know your axle capacity as well as the grease seal, or it's inner diameter. If you don't have this you can measure the spindle where the seal rides to find out.

If your existing drive in studs are 1-13/16 inches long (measurement B in picture) you will need the Replacement Trailer Hub Wheel Studs, item # RG03-040. If your existing drive in studs are 2-3/4 inches long (measurement B in picture) you will need the Replacement Trailer Hub Wheel Studs, item # RG03-080.

    I can point you in the right direction in regards to determining the correct hub and drum for your heavy 14,250 lb trailer, but we would not have any way of identifying the exact hub for your 1995 Trailmax. So there are a number of things you'll need to know to get the right hub; first, you need to know the weight rating of your axle, and also what bearings your current hub has. You will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease...

  • 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.

    From my research it looks like you have 6,000 lb axles on your trailer. You may want to check to see if there is a plate or sticker that shows the axle weight capacity. If you have a 5-bolt brake mounting flange I recommend the Dexter Nev-R-Adjust Electric Brake Assembly, part # 23-459 for the right hand and part # 23-458 for the left hand. These are designed to use with 12 inch hubs and drums. I have attached links to a product review video and an initial setup video for these brakes....

  • Do New Trailer Hubs Have to Have Matching Lug Nut Size as Old Hubs
