How to Measure the Bolt Pattern to Make Sure the Correct Drum is Ordered?

Question

Question:

I measured the rim to find the distance from bolt holes, I have 5 bolts, measured across it is closer to 4 3/4 than 5 inches. But then I measured bot to bolt and I am just short of 3 inches seems closer to 2 7/8 . I dont see any kits for a 5 by 4 3/4 so I guess it must be a 5 by 5.

As you are getting a measurement that is slightly off, I am going to suggest one more way to confirm your bolt pattern. Attached is a link to a printable diagram that will confirm which you have. Make sure you print at 100% on 8.5x11" paper.

We do have a drum kit that matches the Dexter Trailer Hub and Drum Assembly for 3,500-lb E-Z Lube Axles - 10" Diameter - 5 on 5 # 84556UC3-EZ, but has a 5 on 4 3/4 bolt pattern ( # 845476UC3-EZ ), so I highly suggest using the printable diagram to double check.

Thanks for the picture of your trailer wiring connector. You have a standard RV style 7-way connector so for a replacement to match that for your trailer you'd want the part #H20044 which has a 6 foot long wire lead.

Yes, the #84556UC3-EZ is the correct hub and drum assembly and the #23-26-27 will work for brakes. However, you might want to consider the Dexter Nev-R-Adjust #23-468-469 for brakes instead. Since they are self-adjusting, you won't have to…

Answer 6

To determine the size of the brake assemblies you need you have to measure the depth and width of the hub drum on the axle like what you see in the picture I attached. The most common size is 2-1/4 inch wide like the #T4071600-500 that you…

Since Atwood went out of business none of their actuator (or other product) replacement parts are available unfortunately, so your only real option to having a working actuator is to replace the entire unit. I am attaching a link to our selection…

Answer 9

We checked with Dexter and P-21 just indicates where the axle was made. With the serial number we could track down more info on your axle. However, in the mean time you could pretty easily get the bearing numbers off of your current bearings and…
