E-Z Lube-Compatible Assembly for Simple Lubrication

The grease cap on this hub-and-drum assembly is specially designed to work with your Dexter E-Z Lube axle to make lubricating bearings quick and easy. Just remove the plug on the grease cap, attach a grease gun to the zerk fitting on the end of the spindle, and inject the grease. It will flow easily to both inner and outer bearings. Not only does this make lubricating the bearings easy, but it also helps to prevent corrosion of the hub. This is because you can lubricate the bearings without the mess of taking apart the entire assembly.


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 with Integrated Drum - 8-285-11UC3 Review

Rate your transcript OrderClientKevin BrossRef #20688Order #TC0071081117 Today, we're going to review part number 8-285-11UC3. This is the Dexter trailer hub and drum assembly for 8000-pound axles. It has the 8 on 6-1/2 inch bolt pattern and it is designed to be used on an easy lube axle. This hub and drum will fit the 8000-pound axles. This drum itself will have a 4000-pound weight capacity so when it's matched with one on the other side of the axle, it will match your 8000-pound capacity of your axle. This part number does include just the one hub and drum and then the piece is showing here.

Everything shown here is included. It does include the inner and outer bearings. It includes the bearing races, which are already pre-installed in the hub. It includes the grease seal. It includes the easy-lube grease cap with the rubber plug and the eight 9/16 lug nuts. This is designed to fit on easy-lube axles.

It will work with both electric and hydraulic brakes. I just rotate this. I want to show you the inside you can see. The drum dimensions and the brake size that it uses would be 12-1/2 inches diameter. The width is 3-3/8 inches wide.

The pilot hole diameter on this one is a 4-3/4 size. That is considered the new style. The old style was a 4.56. It has the larger pilot hole diameter, in this case, has the 4-3/4 inch, then this is the new style. The bolt pattern, you can see the wheel studs are already installed, so it gives you a bolt pattern of 8 on 6-1/2 inches. The parts that are also included is the inner bearing, which is part number 25580 stamped right on there, the outer bearing, which is 02475.

It comes with the double lip grease seal. That's part number 10-36. It also comes with the easy-lube grease cap. I'll just show you I'm going to take the plug out on it. The reason it's an easy lube grease cap is you're going to be able to access on the end of your spindle that zerk fitting to grease it. This cap will actually have this rubber plug that you can see pulls out and it will give you access to that zerk fitting to grease your hub and drum. It also comes with the eight 9/16-inch size lug nuts. That should do it for the review on part number 8-285-11UC3, the Dexter trailer hub and drum assembly for 8000-pound axles with the 8 on 6-1/2-inch bolt pattern. .

Parts for my old dexter axles After auto parts, trailer dealers and mechanics shops failed me, I found the part on Etrailer. It came quickly, with all the hardware and was $100 less than the trailer dealer told me it would cost if he could even find one. Great job, etrailer. 4339

  • Is Dexter 12-1/4 x 5 Brake Assembly # 23-446 Compatible with Dexter Hub/Drum Assembly # 8-285-11UC3
  • I did not find any purchase history for you but the electric drum brake that you referenced, Dexter # 23-446, is a left-hand 12-1/4 x 5-inch-wide brake. Its matching right-hand part is # 23-447. The hub/drum you referenced, Dexter part # 8-285-11UC3, is a 12-1/4 diameter x 3-3/8-inch-wide hub. These parts do not work together. The brake is rated for 15,000-lb axles while the hub/drum is rated for 8000-lb axles. Both their sizes and weight ratings are incompatible with each other. You...

  • How do Trailer Studs Get Replaced on Trailer Hubs
  • Most are press in studs on trailer hubs. You'll need to hammer out the old ones by hammering directly on the top of the studs until they back out the backside and then hammer in the new ones through the same holes. I attached a link to a page that has all of the drive in studs we offer.

  • Replacement Hub Bearings for 1983 Tandem Axle Motorhome with 02420 Outer Race
  • The outer race # 02420 that you found is used with the # 02475 bearing, which features an inner diameter of 1.250 inches. I recommend measuring the inner diameter of your exiting outer bearing with a digital caliper like # 301-17068 to make sure this matches. When used as an outer bearing it is typically seen on 8,000 pound trailer hubs like the Dexter # 8-285-11UC3, which uses the inner bearing # 25580 (1.75 inch inner diameter).

  • The Dexter # 8-285-11UC3 brake drums are indeed compatible with either electric or hydraulic brake assembles. Your existing drums would work perfectly with the # 23-402-403 Dexter Hydraulic Drum Brake Kit. I would recommend that you inspect the inside diameter of the drums to make sure they are smooth and in good shape.
