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 Axle Trailer Hubs and Drums - Hub - 845475UC1 Review

Today we'll take a quick look at the Dexter Axle Trailer Hub Assembly part number 845475uc1. Now this hub assembly has a capacity of 1,750 pounds. When paired up with another it'll total at 3,500 pounds, which makes it a good application for 3,500 pound axles. There are five studs pressed into the hub that measure 5 on 4 3/4. If we measure from the center of one stud to the center of the next we get a 2 3/4 inch measurement which tells us that it's a 5 on 4 3/4. Now included with the hub assembly are the races which are actually already pressed in inside the hub where they need to be.

You also get your grease seal, which is number 58846; a cap that's going to go over the outside to help keep dust and dirt from getting inside where all your internals are lubricated; your conical lug nuts that will secure the wheel to the studs of the hub; you'll also get your inner and outer bearings. Your inner bearing is L68149 and your outer bearing will be L44649. And that's it for a quick look at Dexter Axle's Trailer Hub Assembly part number 845475uc1.

Excellent quality hub from a well known and trusted manufacturer. 4-3/4" bolt circle not as common as most 4-1/2" bolt circle hubs offered by other vendors, but that suited my purposes perfectly. All parts were included, and I would buy this again without hesitation. 132935


Comments

Its been a year now since I received these, and am still very satisfied. No problems or issues.

Good wheel hubs complete with all necessary mounting parts. Unfortunately one of the four hubs didn't have the correct grease seal with it. One seal instead of having two sealing lips, only had a single inner seal ring with no tensioner spring. If not for that one grease seal it was a good order, reasonable pricing and very quick shipping. 111589

Do you have a question about this Trailer Hubs and Drum?


  • Replacement Trailer Hub Assembly for Dexter 8-248 Hubs
  • The Dexter "8-248" is a hub assembly for 3,500 lb axles that uses an L68149 inner bearing and a L44649 outer bearing. This hub assembly was offered in both 5 on 4-1/2" and 5 on 4-3/4" bolt patterns therefore you would need to confirm your bolt pattern in order to choose the correct hub. I have attached a help article to help you find this as well. I have also attached my recommendations on each hub for you below.

  • 3,500 lb Trailer Hub/Drum with 5 on 4-3/4 inch Bolt Pattern
  • For a hub/drum with a 3,500 lb capacity and the bolt pattern of 5 on 4-3/4 inch like you said you need you'd want the Dexter part # 845476UC3 which would fit and work well. The drum size is 10 inch and for assemblies you'd want the # 23-468-469 for self-adjusting assemblies for both sides of the trailer.

  • Recommended Replacement for a Dexter Hub with a 5 Bolt Pattern and A 2-3/4 Inch Bolt Distance
  • If the 2-3/4 measurement is from center of bolt to center of bolt, then your current hub has a bolt pattern of 5 on 4-3/4. Hub # 845475UC1 does have a bolt pattern of 5 on 4-3/4, but you will want to make sure that your current bearings will match the ones included with the hub. Hub # 845475UC1 uses inner bearing # L68149 and outer bearing # L44649. These industry standard numbers should be lasered onto the back side of your bearings, or if the numbers are not visible, you can always...

  • Replacement Hubs with 5-on-4-3/4 Wheel Bolt Pattern
  • We do offer 5-on-4-3/4 hubs that you can see on the linked page. These include both idler hubs like # 845475UC1 and hub/drums like # 845476UC3. Be sure to check the bearings in your current hubs for their part numbers; new hubs have to use the same bearings or they will not fit on your spindles. The linked photo will show you where to find those part numbers. Also note that mobile home axles are intended for a single use only (to transport the MH) but not for ongoing use like a trailer axle.

  • Bearing Part Numbers and Spindle Dimensions for Selecting New Hubs
  • If you want to switch out the hubs what you need to do is find the bearing and seal part numbers from the original hubs. Any new hub must use the same bearings and seals as the original in order for it to fit properly on your spindles. Examples of those parts numbers are show in the linked image. You can instead measure the spindles but those measurements need to be very precise, and to the nearest thousandth of an inch, like 1.234-inches. You will need a digital caliper like # PTW80157...

  • How To Find Correct Replacement Bearings For Trailmaster Boat Trailer
  • I was unable to find any reference to a Dico 45264 hub. You will need to take some of the measurements to make sure you get the correct bearings and seals for your trailer. Trailer manufacturers use many different sizes when they build their systems and without precise measurements, we could not be 100 percent sure. Digital calipers are available at most tool supply stores. I have attached a drawing that shows where you can take the measurements. We would need to know the inner diameters...

  • Recommended Idler Hub For Boat Trailer With 3,500-Lb Axle

I have attached a link to our product page for the 3,500-lb hubs we offer. The bolt pattern can be a bit different so you will want to determine which one you need.

  • We offer four hub assemblies in the 5-on-4-3/4 inch bolt pattern you need and these can be seen on the link at right. The key to determining compatibility with your spindles is the bearing set used. All of these hubs use the same bearing set, # L68149 inner and # L44649 outer. If your hubs use the same bearing set then they will work. If you are referring to a taper in the mid-section of the spindle (the area between the points where the two bearings sit) this will not matter. In...

  • How to Pick Out Trailer Axle Bearings and Seal
  • I appreciate you giving me info on your hubs, and I can help you pick out the correct bearings and seal, but the info you did give me does not help identify the correct parts you would need. The only two solution I have for you would be to remove the hubs and get the numbers that are stamped on the bearing or for you to remove the hubs and use a digital or dial caliper to measure where the bearings and seal ride (see pic). You will need to get the diameter on the hub where the seal...

  • Replacing Dexter Hubs To Transition to a GMC Truck Wheel Bolt Pattern
  • To determine the correct hub to replace the existing hub on your horse trailer I will need the inner and outer bearing numbers and the seal part numbers to select the proper parts for your spindle. The 8-256 number that you see on your hub is a casting number and even if I could match it to a Dexter hub assembly it would most likely not match up with the correct bearings. Remove a hub and you should find the part numbers on the back side of the bearings and the seal. You will need to...

  • How to Determine the Correct Replacement Hub
  • In order to find the correct replacement hubs for your trailer, 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 and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use a digital caliper such as # 301-17068 and measure your spindle to the thousandths of an inch where the...
