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.

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…

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…

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 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 5

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…

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

The thickness of the grease seal like the #168233 won't matter. You're really just worried about the inner and outer diameter of the seal, so as long as your seal cross references to the National Seal 473317 this will be the correct…

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…

Answer 9

Hey Zachary, are you sure you need the seal to be that thin? Normally variances in seal thicknesses doesn't really affect anything and replacing a thinner seal with a thicker one doesn't cause any issues. If that's case our part #58846…

Answer 10

It would be great if trailer makers kept detailed records of all of the component parts used in their products, but this is rarely the case. No worries, though. You just need to match up a few features. Once you match those features it is easy to…

Answer 11

If you only have the nut and a washer but no cotter pin or retaining type washer on the end then that isn't correct and you want to get a piece to help prevent that nut from backing off. If you have a setup like the Spindle Nut Kit for EZ Lube…

Answer 12

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…
