Recommended Idler Hub Assembly for 1-1/16 Inch Diameter Spindle With Seal 1-1/4 Inches at Spindle

Question

Question:

I read ur email and recommendation, I've compared the bt8 and bt16 spindle and my spindle doesn't seem to match either one exactly, on the pics I'm sending seems like I have the diameter of a bt16 spindle with the grease seal of a bt8 spindle. My question is first of all is this possible and second do I buy a bt16 spindle hub and buy a bt8 grease seal? In addition, the bt8 recommends up to a 12" wheel and I currently have a 13" wheel.

For idler hubs, you will want the Trailer Hub Assembly for 2,000-lb Axles - 5 on 4-1/2 # AKIHUB-545-2-1K or the 4 on 4 inch bolt pattern # AKIHUB-440-2-1K. This is a standard BT8 spindle. I've attached an installation video to assist as well as an article on bolt pattern.

Thanks for the pictures with the caliper. It is an interesting spindle, but it is possible. I recommend the Dexter Trailer Idler Hub Assembly for 2,200-lb Axles - 5 on 4-1/2 # 8-258-5UC1. The bearings and bolt pattern will work with your spindle and your 13 inch wheels. The seal will not work, so you will need to find a seal that will be a perfect fit. We don't have one that is a perfect fit for your spindle and this assembly, but # RG06-010 will be extremely close and will most likely work.

Answer 1

Older classic trailers like your '64 Alpine Sprite may need new hubs in order to use the wheels and tires you wish for that vintage look. The only 4-bolt trailer hub/wheel bolt pattern we offer is the 4-on-4-inch format, like hub #AKIHUB-440-2-1K…

I have a solution for you, but as the short spindles have not been produced for some time now, there will not be a hub that will fit them properly, unfortunately. You will need to replace the spindles with the BT8 Spindle for 2,000-lb Trailer Axles…

Answer 3

The BTR and BT8 denotations refer to the spindle, not the trailer hub. The difference between a BTR and BT8 spindle is that the BTR spindle uses a 1.063" diameter L44649 bearing and the BT8 spindle uses a 0.99" diameter L44643 bearing. In…

Hey Curt! There isn’t a specific torque spec for the castle nut since it’s used to set the bearing preload rather than being torqued to a fixed value. What you’ll want to do is tighten the nut while rotating the hub to fully seat the bearings, then…

Answer 5

Judging by your photo, your trailer would use an idler hub, not a hub drum. Assuming you have 5 lug on 4-1/2 inch bolt circle wheels that use an #L44649 inner and outer wheel bearing, you have a few choices. Rather than the painted hub, I'd…

The tire and wheel combo #AM30120 has a 4 on 4 bolt pattern. You would need to make sure you have the right bolt pattern for the wheel to fit your boat trailer. I have included a link to the right that explains how to determine bolt pattern. If you…

Answer 7

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…

Yes, I contacted a Tech at Dexter Axle for verification and the Dexter Axle UFP Idler Hub, #DA54FR is confirmed to be a replacement for the Reliable Brand, Model BT-150A “short” hub on 2,100 lb. axles. The inner & outer races are included but not…

The spindles of an EZ lube axle are the exact same as a non-EZ-lube. Only difference being the zerk fitting at the end of it. The EZ lube hubs we offer are the same as the non-EZ-lube hubs with the only difference being the grease cap has a rubber…

Answer 10

Hey Steven. What's your question? If your 2,200 lbs axle has a 1-1/16" BTR Spindle you'll have the same inner and outer bearing size item #L44649. You'll need a seal with a 1.25" inner diameter. You can get all of these parts…

Answer 11

I wish we could help but none of our hubs fit a spindle that is 1-1/4 inch in diameter all the way across. If instead the spindle was 1-1/16 inch diameter for both bearings you'd want the part #8-258-50UC1-EZ which is standard for a 2,200 lb…

The difference between the single lip and double lip seals is that the double lip grease seal will have two rubber lips that are in contact with the spindle. The double lip grease seals are usually used in marine applications to give a better seal…
