Video Transcript for Hands-On with the Replacement Race for 3984 Bearing

Today we're going to review part number 3920. This is the Axle Tek bearing race. This bearing race will fit the inner bearing part number 3984. This race is designed to be installed into the hub assembly. That will give a spot for the bearing rollers to ride on the inside taper of this race. The bearing will install in there and ride on this race.

The part number on this is stamped on there, it's 3920. The most important part of this is the outer diameter measurement on the race, because that's the size that will be pressed into your hub assembly. It is measured in thousandths of an inch, so it does require the use of a digital caliper to get a correct measurement. Just to show you here, the outer diameter on this part is going to be 4.438 inches. That should do it for our review on part number 3920.

  • Replacement Hub and Drum Assembly for 15,000 Pound Axles
    Although I do not have an option to retrofit your hubs I do have a solution.

If you're just looking for replacement races, bearings, and seals we have those available as well. This hub uses an 8 on 275 mm bolt pattern. It would also require switching to oil bath from the grease. In addition to the hub and drum assembly, or for replacement bearings and seals, you would...

  • Are There Any 15K Trailer Idler Hub Assemblies Available
    The only 15K rated hub assembly that we currently offer without the drum would be Dexter part # DX42KR. This hub has an 8 on 275mm wheel bolt pattern and uses the following bearings, races, and seals: Inner Bearing Cup # 3920 Inner Bearing Cone # 3984 Outer Bearing Cup # 28622 Outer Bearing Cone # 28682 Oil Seal: # 10-56 Hub Cap: K71-148-00 Prior to purchase I recommend checking to make sure the bearings and seals will match your current setup, as well as the wheel bolt pattern so...
