Expert Reply:
We can definitely get you replacement bearing kits for your Dico 40511 brake drum, but I was unable to find out what it originally came with, unfortunately. So with that being said, you will need to either measure the inside diameters of both the inner and outer bearings to confirm the parts needed, or see if there are part number stamped into them. These part numbers do wear off over time, however, so measuring may be the way to go. This should also be done with calipers, like the Performance Tools # PTW80157, as it does need to be as accurate as possible.
As an example, the bearing kit # BK2-100 will come with the inner bearing # L68149, which measures 1.378", and the outer bearing # L44649, which measures 1.063". This is a pretty typical set up for a 3,500 pound Dexter axle, but again, should be verified before getting too far ahead of ourselves.

I have a 2002 Escort trailer with the same DICO 40511 drum. The drum also had OE25 and WFT stamped on them. They have 6 bolts/lugs, so I assume that means the trailer capacity is 5,200-6,000. Is there a brake kit part numeber for this type of DICO brake drum?
