Trailer Hub Assembly
- Capacity of 1,250 lbs per each
- 5-1/2" Diameter Hub Flange, for use with 8" to 10" Wheels
- Bolt Pattern: 5 on 4-1/2 (for information see below)
- Bearings (L44643 Inner/Outer), Races, Cap (1.986"), and Seal Included
- Inner bearing dimension is 1.00"
- Inner seal dimension is 1.249"
- Dexter #8-259 - should be stamped on back of hub
Please Note: Some axles rated at 2,000 lbs require a different seal and bearings. Be sure that the bearings in the hub being replaced have L44643 stamped on them. If the bearings have L44649 stamped on them, use #8-259-5UC1 trailer hub.
Note: Most trailer tires that are smaller than 15" and have 5 bolts, have a 5 on 4-1/2" bolt pattern.
How to Measure Bolt Pattern
The first number in the bolt pattern is the number of bolt holes. The second number is the diameter of the circle the holes sit on. To determine the diameter on wheels with an even number of bolt holes, measure center-to-center on bolt holes directly across from each other on the circle (Example: 8 on 6-1/2 would mean 8 bolt holes with 6-1/2" center-to-center diameter). When the number of bolt holes is odd, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from it on the circle (Example: 5 on 4-1/2 would mean 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolts).
AND / OR
The distance between the center of one bolt hole on the wheel to the center of the bolt hole right next to it will also help determine the bolt pattern.
- If D = 2-5/8" then the bolt pattern is a 5 on 4-1/2
- If D = 2-3/4" then the bolt pattern is a 5 on 4-3/4
- If D = 3" then the bolt pattern is a 5 on 5
- If D = 3-1/4" then the bolt pattern is a 5 on 5-1/2
