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.

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.)

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.)

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"

Today were going to take a quick look at Dexters Trailer Hub and Drum Assembly part number 84557UC3. This drum assembly is designed to work on 3500 lb axles. It has drum dimensions of 10 inches by 2-1/4 inches wide. The bolt pattern is 5 on 5-1/2 and you can measure that by measuring from the center of one stud to the center of the next. We get 3-1/4 inches which comes out to a 5 on 5-1/2 bolt pattern. Included with the kit are the races, bearings, seal, cap and lug nuts.

The races are already pressed inside into place so theyll fit over your spindle. Youve got the inner bearing which is L68149, the outer bearing L44649, the seal and of course the nuts and the cap. This drum has a capacity of 1750 lbs so when you pair it up with another drum youll get your total of 3500 lbs for the axle. Well go ahead and go over the measurements inside. Across the inside of the drum we get our 10 inches and for our depth we get about 2-1/2 inches which is enough space for 2-1/4 inch wide brake assembly.

And thats it for a quick look at Dexters Trailer Hub and Drum Assembly part number 84557UC3.

• Converting 3500 lb Axle from Idler Hubs to Electric Brakes
• The brake mounting flanges, whether they be 4 or 5 bolt, have a standard hole spacing to fit their appropriate brake assembly.

You will need to get the numbers that are stamped on your existing bearings, in order to confirm the fit of the # 84557UC3. Your current bearings will need to match the bearings of the replacement hub. The # 84557UC3 uses L68149
