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…

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…

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 4

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 John, thanks for reaching out. It sounds like you need the Timken Grease Seal #TMK36ZR which is I.D. 1.250" / O.D. 1.983". As far as the bearings it sounds like your hub uses the L44649 bearing which is the 1.063" ID. This goes…

Answer 6

It sounds like the remains of a double lip seal. Was it like a rubber o-ring with a metal spring around it? You are going to have to replace the seal so I would just disregard the sleeve. It would go on the outside of the rubber lip though. I…

Answer 7

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…

Answer 8

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 9

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…

Answer 10

The part you referenced 127194TB is a double-lip seal with an inner diameter of 1.274-inches and an outer diameter of 1.983-inches. The available seal nearest to those dimensions that we offer is part #RG06-010, which is a double-lip seal sold as a…

Answer 11

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"…

Answer 12

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…
