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…

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…

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…

Hey Michael, 3/4 inch diameter spindles are basically unheard of nowadays so you won't be able to find one. The 1 inch diameter of the 1-1/16 inch diameter spindles are the current size that is most likely seen. You'd need to know the…

I have a solution for you, but we do not have a double lip grease seal with the exact measurements you specified. However I was able to find out that the GS-1250 DL that you mentioned has the following measurements: Inside Diameter: 1.249"…

Without knowing which specific part number hubs you're speaking of, it's hard to say what the differences are, but I can give some generalities that might help answer your question. The specific hub you'll need will depend on the diameter…
