How to Tell if Trailer has a BT8 or BTR Spindle Installed  


I need a hub, wheel and tire, lug nuts. Its a 1 inch spindle shaft. How do I know if it is a BT8 or BTR or what?


Expert Reply:

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 dimensions of 1.06 inch for outer and inner bearing plus 1.50 inch where grease seal would install. That would require an idler hub part # AKIHUB-545-2-G-2K.
