'46-'48 Drum Assemby

[flathead34]

I need to press(swedge) the hubs onto the drums. These are '46-48 drums/hubs with the hubs mounted from the inside of the drums. Any suggestions on how to do this. Do you press the hubs on to the drum or press the drum on to the hub? At suggestions would be appreciated. Thanks, Mike

I'd press in Dorman 610-109 studs and use new MT drums. These stud you drill/ream a hole and press in. They don't have to be wedged in. Much easier to install and drum fit like modern ones. https://www.summitracing.com/parts/r...FY62wAodZFEGFQ

Are we possibly talking about the word "SWEDGED", in stead of "wedged"? DD

I've done hundreds of these....

Start the process by removing the old studs. These must have the old swage cut off using an expensive flycut type tool. This cuts the surface of the drum with the stud, making the drum unusable. The alternate method is to drill the heads of the studs off the back side, drive them out the front with a hammer and punch.

MEASURE the old studs, compare to the new ones. The new should be the same size or a BIT bigger. (Maybe .010). If larger, they can be cut down- I've done some with emery cloth -sandpaper. If they are larger by a knurl, they can have more interferance.

Use a large flat file to go over the flat surface of the hub where the stud holes are. You will find that the old process raised up the metal over the holes.

The new drum should fit right to the hub by hand.

Put three of the studs in from the back and use the lug nuts to hold the drum to the hub. Press in two of the new studs and swage them. Do the other three one at a time.

I've used a large professional press with the correct tools to do this.
I have the remnants of a hammer operated set up to do this. (Never will)

Find the guy with the press and tooling- or live with the drums held to the hub with the wheel bolted to it.

New drums HAVE to be machined using the hub they will be used with.

There is more to it than this, feel free to contact me with your phone #.
I'm near SF, Ca.
