  • Idler Hub and Spindle Recommendation with 5,200 lb Capacity and 6 on 5-1/2 inch Bolt Pattern
    For a spindle that fits the hub part # 8-213-5UC1 you'd want the part # 52655IEU which comes with the 5,200 lb hub you mentioned and the correct matching spindle for you to install. The hub you mentioned will not fit the agricultural spindle you mentioned due to the difference in seal dimensions.

  • Parts Needed to Add Electric Drum Brakes to Trailer with Idler Hubs
    You can add electric brakes to your trailer by selecting a hub/drum assembly that uses the same bearing part numbers, weight rating and wheel bolt pattern as your current idler hubs. It is possible to take measurements of the spindle at the points where the bearings ride (see photo please) but this requires a precision caliper like # PTW80157.

  • Which Hub Assembly is Compatible with the Agricultural Spindle # TRU34FR
    Although the outer bearing of the # AKIHUB-655-6-K hub assembly will fit, the inner bearing will be too large. Instead, you'll need the Complete Agricultural Hub Assembly, # AH30660FCOMP, which is designed to fit the agricultural spindle # TRU34FR. I've attached a couple of review videos for you to check out.
