Are These Lugs Swaged To The Drum?

Use a short pipe or a deep well socket that fits over the head of the stud on back of the hub. press or hit out the studs one stud at a time pushing it through the hub. If using a hammer use a brass drift so not to damage the threads. this will remove the swedge from the stud. It is important to hold the hub , Do not ever push on the rear of the drum you must old the hub so not to damage the flat surface of the hub.

Then press the studs back in using the same method one stud at a time the opposite direction into the hub. once the studs are back in the hub your drum will now just be a slip on like the rear drums. remember to hold the hub with a pipe or socket for each individual stud . You can pull the studs back in with a lug on backwards and a spacer if you don't have a press.
