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"

  • How to Choose a Replacement Dexter Hub/Drum Assembly
    Dexter hub drum assembly # 8-219-13UC3 is a replacement for your hub drum according to my contact at Redneck Trailer Supply. This is rated for 7K, has a 8-on-6-1/2 bolt pattern and 9/16-inch studs.

  • What's Difference Between Trailer Hubs # 8-219-9UC3 and # 8-219-9UC3A
    The two hubs are very similar but the big difference is the size of the seal that comes with the hubs. The # 8-219-9UC3-A comes with a seal that has an inner diameter of 2.25 inches and the # 8-219-9UC3 comes with a seal that has an inner diameter of 2-1/8 inches. You'd need to measure your current spindle where the seal rides to determine which you'd need.

  • Can Grease Hub of 2010 Heartland Big Horn 36RL70 Be Changed to Oil Bath
    The grease hubs can be converted to oil bath by just switching the hub to an oil bath setup like the part # 8-219-9UC3 that you referenced. To verify that this will fit your spindle you'll need to pull your hub off and measure where the bearings and seal rides. If the dimensions are 1.75 inch and 1.25 inch for the bearing surface and then 2.125 inch where the seal rides then this hub will fit and work well. If you have different dimensions here let me know and I'll see what the best...

  • Replacing Grease Lube Hubs with Oil Bath Hubs
    You can most definitely add oil based hubs to your trailer axles. If you have 3,500 lb axles you can use # XLPROLUBE1980KIT to convert your grease hubs to oil based hubs. With this kit you will need to pop off your old grease hub caps. You will then clean all of the grease off the spindle, hub and bearings. Lastly, install the new oil bath hub cap by tapping it into place and fill with oil. If you have a larger size axle there is no way to convert the hub for oil based. You will need...

  • How to Determine if Trailer Hub 8-219-9UC3 Would Fit Spindle
    I'd need more info on your axles to know if the hub you mentioned would fit. Is there a sticker or label on it with any info/part numbers? Otherwise you'd have to pull off a hub to get me the dimensions of the spindle or the bearing numbers. The # 8-219-9UC3 uses bearing numbers 25580 and 14125A and has spindle dimensions of 1.25 inch and 1.75 inch.

  • Changing Trailer Hubs from Grease Type to Oil Bath Type
    Oil bath hubs have a threaded bore that accepts the threaded oil cap that lets you see the oil level. If you want to change from grease-lubricated hubs to oil bath lubricated hubs you will need to make sure that your current bearings match up to those in one of the oil bath hub kits we offer, either # 8-219-9UC3-A or # 8-219-9UC3. Both of these hubs use the bearing set # 25580 inner and # 14125A outer. If your current hubs use this bearing set and if their 8 on 6-1/2 inch bolt pattern...

  • Parts Needed to Replace Grease Lube Hubs with Oil Bath Hubs
    You will not need to replace the brakes on your trailer when converting from grease lube hubs to oil bath hubs. The oil bath hubs that you choose should come with the proper bearings, seal and oil cap for that hub. You will want to check the part numbers on your bearings and seals to ensure you select the correct hubs for your spindles. We carry two oil bath hub and drum assemblies.

  • Are Oil bath Hubs a Better Option for My 7,000 Lbs Axles Than Using Grease Hubs
    The main reason people like oil bath hubs over grease hubs is the oil bath hubs have a less involved maintenance schedule than grease hubs. It is recommended to inspect and repack grease wheel bearings and seals every 12k miles. With oil bath hubs, Dexter recommends to periodically check and refill when necessary. It is also recommended to use a high quality hypoid gear oil in SAE 90, 80W-90 or 75W-90 weights. However, periodic inspection of you wheel bearings should not be abandoned...

  • Hub and Wheel Recommendations for Converting to Oil Bath Hubs
    As far as caps are concerned the main difference between an oil and grease caps is how they have to attach to the hub. Grease hubs will press in, while oil seals need to be screwed into a threaded hub. You will need to upgrade to oil bath hubs. We have oil bath hubs that would fit your spindle, except they all have an 8 on 6-1/2 inch bolt pattern. One of them is the Trailer Hub and Drum Assembly # 8-219-9UC3. This hub would work on your trailer, but you would need rims that have the...

    If you had a 3,500 lb axle we sell a kit that would easily convert your hubs to oil bath hubs. But since you have 7,200 lb axles you would have to replace the hubs. The oil bath hubs that you choose should come with the proper bearings, seal and oil cap for that hub. You will want to check the part numbers on your bearings and seals to ensure you select the correct hubs for your spindles. We carry two oil bath hub and drum assemblies.

  • Converting 7,000 Pound Grease Hubs Over to Oil Bath Hubs
    To replace your grease caps with oil bath, you will need to measure the bore of the hub, where the cap sits. The Lippert hubs that were used on their axles can have some odd sizes so it is a good idea to double check. With that being said, if the measurement you get is over 2.25", you will need to replace the hubs. If this is the case, you will need the Dexter Trailer Hub and Drum Assembly - 5,200-lb to 7,000-lb Axles - 8 on 6-1/2 - Oil Bath # 8-219-9UC3-A if your seal has a 2.250" inner...

  • Which Magnet Fits etrailer 12x2 Electric Brakes for 5.2K to 7K Axles and Oil Bath Hub for 7K Axles
    The magnet used in trailer brake assemblies # AKEBRK-7-SA is magnet # AKBRKR-M12 which you will see they have rated the same as the brake assemblies themselves. So since they are compatible with up to 7K axles you can say they are rated for 7,000 pound axles maximum. We have tow hub and drum assembly kits for 7K oil bath axles. First is # 8-219-9UC3-A and it comes with a 2-1/4 inch diameter seal. The other is # 8-219-9UC3 and it comes with a 2-1/8 inch diameter seal. The oil cap included...

  • Can Existing Grease Lube Hub Assembly be Replaced With Oil Bath Lubrication
    I would recommend that you install Trailer Hub & Drum Assembly, part # 8-219-9UC3, on your trailer. This hub is identical to the Trailer Hub & Drum Assembly, part # 8-219-4UC3, that you referenced except it is setup for oil bath bearings instead of grease bearing. These hubs have a 2-1/8 inch seal. The Oil Cap Kit, # RG04-270, is threaded and would only work on hubs that are threaded for screw in style caps. This would not work on the # 8-219-4UC3 as it takes press in style caps.
