Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.


Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: 8 on 6-1/2 means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)


Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: 5 on 4-1/2 means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)


Bolt Pattern - Side

Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Overall product quality is pretty good for the price , no issues with casting or bearings which is what counts . Dust covers are the usual stamped steel so there is a pretty good burr lip that needs a bevel to help start it inside the hub bore - just be aware of it and it makes the job much easier .

I used these hubs to do a conversion on a garden tractor - going from very small lightweight ball bearing stamped style 1" inside flanged push-in type to trailer hubs and 8" - 4 bolt trailer rims - can't say enough about how much better this upgrade works and much more serviceable on my old Wheel Horse . For those running a loader on the larger garden tractors this upgrade is a must unless you like buying new wheel bearings constantly - this conversion will last a lifetime if cared for properly . E-Trailer is always great at answering questions and will help with dimensions if you ask - that is priceless in today's world of non-support retailers , wish other outlets would handle customer service like E-Trailer .
I won't hesitate for a second to buy needed parts from these guys - good pricing , fast shipping and details that others won't take the time to include with product listings . Got my trailer brake controllers for both trucks , several other build parts to wire my trailer for a full 7-wire system including fused power feed and reverse lights - thrilled with everything I've ever bought from them . Will be back in the future , that's for sure .

For those who has the Harbor Freight 62645 (40-1/2? x 48?) utility trailer that has the .98**" shaft and 1.181" (30mm) seal shaft . Yes this is your hub, just need to replace the kit seal with a National 473426 seal.
For my purpose, changing from the 4.80-12 4 ply to a 145R12 10 ply tires I used 1" 4"x4" wheel spacers. The wheel studs was to long, so I purchased and installed the (K12WB169) Kodiak Wheel Bolt - 1/2 Diameter X 1-7/10 Long. Perfect fit!
This kit has a little bit heavier bearings, so the castle nut may have to filed a little bit to get the cotter in, due to the so called Chinese precision notches. No one locally have a replacement castles nuts. I will replace these a later when I find better quality ones.

My brother in law's old side delivery hay rake broke down. The carrier bearings and housing for the rake teeth bars and carrier assembly were totally gone. This thing is probably from the 50's and parts no longer are available. I looked it over and figured that a trailer hub and spindle shaft could be modified as a replacement. Ordered a 4 on 4 hub and a 1.25" spindle from etrailer. The parts were in my hand in 46 hours and as of today the rake is back in operation. Turned out to be a pretty easy fix since the 1.25 spindle fit perfectly into the old mount and just had drill a retaining pin hole and had to cut off about 3/4 " of the weld end of the spindle to get the correct spacing. The lug bolts fit snuggly into the hole from the original bearing housing which helped line up the assembly. All I had to do was fabricate a round plate with holes for the hub's lug bolts which was then bolted to the larger wheel which carries the rake teeth bars.

Still working great.

I was able to easily install the hub, and since it was pregreased there was no mess with wheel bering grease



by:

Had a cracked hub on a kayak trailer build. Heard about e trailer and wow. What I needed I also had to pay shipping but even then the hubs was 20 a piece cheaper online and 30 a piece cheaper than local. These hubs was upgrade so I don’t have to fight bolts when putting wheel on. Great price and product. I am hooked on getting all my stuff from them in the future. They even threw in the quicker shipping with no additional cost to me. You can see what I had and got in the pictures



by:

Bearings are pre-greased and the hub is capped with plastic plugs on each side for clean shipping. I really like etrailers attention to detail. Thanks!



by:

I ordered and installed a pair of Trailer Hub Assemblies from etrailer to replace the failed and rusted hub assemblies on my motorcycle trailer. The new parts fit perfectly and the job was easy to complete thanks to the provided instructions. The sales person at etrailer was very helpful in finding the correct hub assemblies for my particular trailer and the new assemblies were mailed within 24 hours of my order. I also appreciated the tremendous value, I spent much less than what I expected to pay for a hub assembly. Thanks etrailer, I will use you again!

The hubs are still performing well!

Got exactly what I needed and as usual service from etrailer was excellent. Hats off to Teresa with helping me get the Hubs and Bearing Buddies I needed and then getting me the parts in a very timely manner. Thanks Guys!



by:

I used these to modify my craftsman tractor that had clips holding the wheels on and kept breaking off. These, along with the spindles I bought solved all of my issues with a little fab work. Great value hubs and they’ve held up really well to the abuse of my rough yard.

Still taking a beating and no issues!

Cheap price. Lightning fast shipping. Great product. The only thing that could make it better is if it came with the outer washer an cotter pin but no biggie. They're like 80 cents each so I could just run to the hardware storev an grab some. Fitment was spot on thanks dust cap was a little tough to get on but I just slbent the sides a little an she went right on.



by:

etrailer.com is the best place to buy. Always fast delivery and always exceeds my expectations on quality. I have ordered from them many times and I am always happy with their service and products I have received.



by:

I purchased these hubs, spindles, wheels and tires for a machine that I'm building. Initially, I tried to source them locally, but nobody had all six items that I needed. So I turned to etrailer again, and was very well pleased. All the items are of very high quality and work together without any modification. And the price, including the (free) shipping from etrailer was less than any local vendor, and they were delivered in less than a week. etrailer comes through once again! Thank you, etrailer!



by:

Your representative answered my questions before I placed my order. The part came in, looks like a match. I will keep you posted as to how it works out. Shipped out as told, received as expected.



by:

Everything came packaged good and ready to go. It was very affordable and of good quality. I would recommend it to anybody in need of more bearings. The shipping is really good with keeping you up where your package is and how long you have. It also doesn’t take long for your shipping. Overall I am impressed and I will definitely be back!
The dent on the cap is from me putting in on by the way lol



by:

all items are as described and of good quality.shipping was ahead of scheduled time even with a holiday during that period.i will continue to use etrailer for any products they carry. GREAT JOB-ETRAILER.



by:

I have pulled the trailer with these hubs for over 3000 miles now. They have worked great and the ride is very smooth. These are great hubs!


Comments
Its been over a year now and Ive pulled the trailer around 6500 miles. The hubs have done well and Ive had no issues with them. I have bearing buddies on them and grease them every ~2000 miles. Ive had loads that pushed the upper limit of the tires and it was no problem. The trailer has always pulled straight and true.

Great quality products and open communication with etrailer.

Restored a vintage boat trailer. The hubs and bearings worked perfectly. Excellent quality.



by:

Trailer hubs with bearings pre-greased were the way to go, and fit on my 60 year old Holsclaw boat trailer perfect. Only complaints were the grease / bearing caps. The would not tap in the hubs as is. Edges were very rough and seemed "oversized". Only way I could get them in was to sand them on the belt sander. Also, be aware that the studs on these hubs are extra long, and an ordinary lug wrench may not be deep enough to get the nuts on or off.



by:

Great service. Great videos for learning. Great product. Went on perfect. I’m glad I watched the video , because I ordered the wrong hubs the first time.



by:

The products were perfect and brought my 25 year old trailer back to new! The most wonderful part of the repair was talking to Carla at the help desk. I could not reach a comfort level as to which bearing/seal/hub kit to buy and she was exceedingly patient in having me measure mic clearances and direct me to etrailer's appropriate web sites so we could both see and talk about the same thing. Then, when I was 99% sure of the right kit, I expressed concern about one measurement that HAD to be correct or I would be shipping it all back. This was not available in the product description so she offered to go find the kit, get the measurement and call me back! Measurement confirmed! I ordered and have now installed. Carla went above and beyond.......thank you Carla and thank you etrailer!

After toasting a set of bearings in my old hubs on a light boat trailer, I decided to go ahead and replace the whole set. My old hubs didn't have studs / lugnuts, so this was a great upgrade. Everything worked fine replacing on a BT8 spindle, except I had to replace the washer between the outer bearing and castle nut with a thinner washer. The SW1000 washer was too thick and wouldn't allow cotter pin to be installed. Would recommend to a friend!



by:

Product is perfect.

Makes replacement
VERY easy with virtually no mess! Bearings in the hub are greased and seals are installed. Everything is new- hub, studs, wheel nuts, inner and outer bearings, seals and covers.

Excellent value that saves money and time over replacing wheel bearings and seals in your existing set up.



by:

These new hubs were just what the doctor ordered to repair my utility trailer. The bearing failed in my old hub so it was easier just just to buy a whole new unit. Actually I bought two since it makes more sense to replace them in pairs.

The best part was these hubs come pre-greased, and ready to install right out of the box. My only complaint, and it's not really a big deal since I knew this up front, was a new cotter pin is not included. My suggestion would be to include a new cotter pin, but otherwise these hubs were great.



by:

Great hub assy. I used these hubs to replace out of date hubs on my Tee Nee trailer. Could not find seals to fit the old hubs. Like how the new hubs were pregreased and had caps to keep the hubs clean.. Very good price, cheaper than the bearings and seal to fix old hubs.
