Fit and Compatibility of Drum/Hub on # 42 Spindle

Question

Question:

I have a dual axle trailer with a #42 tapered spindle 1.2495 outer spindle diameter and 1.7495 inner spindle diameter. Bearings are 15123 and 25580 currently in use in a mobile home trailer hub like your item Code: 8-174-5UC3. I wish to up grade to 8 on 6-1/2 drum hubs and run a 16inch tire Why will your item AKHD-865-7-2-K not work on my #42 spindle? Thanks

The # 14125A bearing has different applications than a # 15123 bearing. The outer diameters are different. Which is why the # AKHD-865-7-2-K will not work on your #42 spindle.

If you have a # 15123 bearing then you would need that same bearing as a replacement.

The only hub and drum with a 8 on 6-1/2 bolt patter that will work for an inner bearing of # 25580 and outer bearing of # 15123 is the # 8-219-50. This hub and drum will be compatible with 12x2 inch electric and hydraulic brake assemblies.

I have linked the brake assemblies that will fit this drum/hub for you to choose your preferred brake component like manual or self adjusting.

I have also linked all the above mentioned parts to this page for your viewing and purchasing convenience.

To determine the size of the hub assembly you need to purchase you have to determine which bearings are in the old assembly. If the old assembly has L44649 inner bearings, you would use the hub you chose #8-258-5UC1. If the inner bearings are marked…
