Replacement Hub Drum for Hayes 8k Trailer Axle  

We do offer a grease cap for an oil bath hub that has a 2-7/8 inch diameter at the threads, part #RG04-230, however the total height of the cap is 1-3/4 inches. This is the closest thing we offer to the oil bath cap you referenced.

The comparable Dexter product would be part #8-285-11, which is an 8K 12-1/4 x 3-3/8 hub/drum with a 8 on 6-1/2 inch bolt circle. The drum comes with the races already installed, but the #25580 and #02475 bearings and #RG06-070 grease seal are sold…

An 8-285 hub does not have the correct bearings or races to work with Bearing Buddies, so you would need to use a standard grease cap. For example, the #8-285-11 hub and drum needs Trailer Hub Grease Cap #TRU66FR for a quantity of one or #RG04-120…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

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…

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…
