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"

Ask the Experts about this Dexter Axle Trailer Hubs and Drums

  • Grease Cap for Dexter 8-285 Trailer Hub
    An 8-285 hub does not have the correct bearings or races to work with Bearing Buddies, so you would need to use a standard grease cap. For example, the # 8-285-11 hub and drum needs Trailer Hub Grease Cap # 21-43-1 for a quantity of one or # RG04-120 for a quantity of two.

  • Recommended Hub and Drum Assembly with 5/8 Inch Studs for 8,000 Pound Dexter Axle
    The 008-285-11 number you found on your existing Dexter hub does refer to the Dexter Trailer Hub and Drum # 8-285-11, however as you mentioned, this particular assembly uses 9/16 inch wheel studs. This is the case with all of our grease lubed hub and drum assemblies that are designed for 8,000 pound axles. We do have the Redline Trailer Hub and Drum Assembly # 8-285-10UC3-A, which will work as a replacement on your axle. This is an oil bath hub and drum that uses the same # 25580 inner...

  • 2015 Palomino Sabre 36QBOK Brakes and Bearing Recommendation
    I looked in several places online and couldn't get a definite axle capacity for your trailer. I'd assume it's a pretty high capacity since it's a tandem axle trailer that weighs 12k and has 3k of capacity. So most likely you have 8k axles like what the part # 8-285-11 hub fits which has bearing numbers # 25580 and # 02475 with grease seal # RG06-070. Then for brake assemblies part # AKEBRK-8. Get me the diameter of your axles though and I'll be able to get you a better recommendation. Typical...

  • Is it Necessary to Grease the Hubs on a G-45 Tipper
    If is has wheels and bearings then it's going to need grease (or oil if it is an oil bath hub). I have included a link to a video that shows how to pack bearings with grease by hand. We also have a tool that can be used, # L70025, that you can use with a grease gun, # L30100, to limit the mess. Also, you have to make sure that the grease used is compatible with the grease still on the bearings and in the hub. If you are not sure then you will need to completely remove the old grease...

  • Meaning of 8 on 6-1/2 Inch Bolt Pattern for Dexter Hub # 8-285-11
    The 8 on 6-1/2 inch description that you see for the Dexter Trailer Hub # 8-285-11 refers to its bolt pattern. It is important to note this feature when replacing your hubs because it needs to match the pattern on your existing wheels for the wheels to mount properly. If you are unsure what bolt pattern is on your current hubs or wheels you will just need to take a quick measurement to determine this. For a wheel or hub with 8 bolts, you will simply measure from the center of one bole...

  • Are 8k Dexter Trailer Hubs a Fit for Both Sides of the Trailer
    Trailer hubs are not directional like brake assemblies are. The number you mentioned is very similar to the # 8-285-11 which is a fit for both the right and left side of the trailer. The electric brake drum assembly that fits the 8-285 hub and integrated drum would be the Dexter Electric Brake Assembly-Left Hand, part # 23-434, for the left side and Dexter Electric Brake Assembly-Right Hand, part # 23-435.
