Questions: How much pressure is required to press new studs in through these drums? Would a 6 ton shop press do it, or does it need something heavier duty?
Question By: Bradley on Apr 22 2021 3:37 PM
I would think that would do it. Please give it plenty of backing so it doesnt warp or bend. Thanks!

Questions: Can I order the A472 rear brake drum, 811351 rear wheel hub, and A474 studs as a complete assembly instead of individually? I don’t have a way to install the hub onto the drum face myself.
Question By: Drew Higley on Jan 5 2020 8:40 PM
You will have to have a local brake/machine shop hydraulically press them together. Make sure they give it plenty of backing.

Questions: How are the brakes adjusted with these drums? The originals have a slot to get a feeler gauge into. These do not have that slot.
Question By: 4D7_2A on Aug 20 2013 12:00 AM
You have upper and lower brake shoe adjusting eccetrics. You mechanics manual will detail it. You have to raise each wheel individually and turn the eccentrics in. Then adjust out untill you heard a audible drag but not enough to cause friction.

Questions: How do you get the rear drum and hub back on the axle completely? The brake shoes are fully retracted and not dragging. I have completely cleaned the inside of the hub and axle shaft. The drum won't go on the last 1/2 to 3/4 inch. Thanks
Question By: john on Sep 25 2012 12:00 AM
The hub mounts on the outside of the drum. Make sure this is done properly. Also make sure the eccentrics are turned all the way in on each side. Then make sure the wheel cylinders are compressed putting the fluid back into the master cylinder. Also make sure all bearings are full seated as well as axle shaft.

Questions: I have a broken rear brake drum. My front and rear drums appear slightly different, (the front ones are slihtly deeper). You show only one kind for both front and rear as replacments. Is there a difference between front and rear drums? My jeep is a '49 CJ-3A
Question By: John on Sep 23 2012 12:00 AM
They used the same drums front and rear on the Willys. This will be proper.

Questions: How do I get the hubs off if my lugs are stripped? I cannot get the lug nuts removed. It is a 1952 CJ-3A. This project has been sitting for a number of years. The jeep runs and I just replaced the master cylinder, yet I get no brake movement from the drums. I assume the wheel cylinders are frozen. Any suggestions or advice is greatly appreciated.
Question By: Clif on Apr 19 2012 12:00 AM
Keep in mind some of the threads are reverse thread. That may be your problem. Alittle heat goes along way too.
