Re: Eaton HO72/HO52 vs. 14 Bolt FF

Hi, I have a question about swapping a 68 HO52 brake set up to a 14 bolt 13" brake setup. You mentioned the bearings ahve different diameter, but the backing plate of the 13" brakes will bolt up to the HO52 housing, correct?

Now my question is, sure you could turn down the spindles and run the 14 bolt hub and make it work that way, but I was wondering, would it be possible to just turn out the bearing race diameter in the 14 bolt hub to accept the HO52 bearings and then bolt that setup with the original HO52 bearings onto the spindle?
I doubt that you can just use the HO52 hub, put the 14 bolt drum on it and mount it up, as your picture shows the 13" drum is deeper, so therefore the hub would come out further too and the bearing seats wouldn´t line up on the spindle anymore...or am I wrong? Is the backing plate of the 13" drums set in further, so that would actually work?

Could it be possible, I just take the 68 HO52 hubs, bore the stud holes out for the 9/16" studs, mount up the 13" drum and backing plate and bolt it all on the HO52???

Thanks!

Check out the different welds on the 71(top) and 69(bottom) Eaton brackets!





14 bolt and Eaton threads are the same. This is the 14 bolt spindle nut on the Eaton


The 14 bolt bearings are smaller than the Eaton. They have a smaller ID and OD
