Classic/Antique Car Repair: rear break drum removal, packards international, rear brake drums


Question
How do I remove the rear brake drums from a 1939 Packard 120. Tried to get off are they possibly gaulded? Thanks any help you can give is appreciated.

Answer
Hello William,

The rear axle on so-called "junior" Packards utilize a "semi" floating axle design with a tapered end over which the drum is press-fitted. Over time, they can get rusted on. To get one off, you will need 4 things: a "puller" (a spider finger looking thing that bolts on to several of the lugs and has a center screw  to turn against the center of the axle. They are available for rent at most auto stores or Rent-All places), penetrating lubricant (I prefer "PB Blaster" in the yellow can available at most auto stores and Walmart), an acetylene torch or similar HOT device (your little propane torch for soldering won't get the metal hot enough) and lastly and most importantly, patience! Before doing anything, I'd spray the drum/axle interface generously with the penetrating lubricant and let it sit for a day. Then spray it again and try your puller. If no success, take your torch and heat up, the interface area cherry red and let it cool several times, then try your puller again. Finally, carefully tapping all around the joint and drum with a 5 lb hammer might just do the trick after all else has failed.

And if THAT fails, call your local chapter of Packards International or similar and ask for some help from one of their technical experts. This is a  common problem for many cars of this era, particularly MOPARS, that the experts have developed into almost an art. If you get stuck, network with these guys; they have been almost unfailingly helpful to me. Good luck!
