Hi Joe,
The BD3-655 has been discontinued and I wasn't able to find a reliable source for what bearings it uses so I'd need you to either see if you can read the part numbers off of them and the grease seal or have you measure the spindle at points B, C, and D from the diagram below with a caliper # PTW80157.
I'm fairly certain that the Trailer Hub and Drum Assembly # AKHD-655-6-K is going to be the correct fit but you can double check the bearings and seals compared to your current ones:
Inner bearing # 25580 (1.75" inner diameter)
Outer bearing # 15123 (1.25" inner diameter)
Grease seal # GS-2250DL (2.25" inner diameter)
