I brought an air shift transfer case down to my shop today and threw it on the scale...465 lbs! It still had the parking brake assembly and drum on as well as the cross-member and gear oil. I knew they were heavy but wouldn't have guessed that much.

I'm bringing this topic back to life. It's an interesting read, and now I have a query. How much does the 60-amp alternator weigh? I might need to pull an alternator out of my truck and the manual says it's a two-person job.

I recently bought a rebuilt transfer case mounted in the lower half of a shipping can for my M813. In total, it weighed 1,000 lbs. I think Wes said a T138 transfer by itself weighs 644 lbs. A friend told me the shipping can weighs around 300 lbs.

Here's another question: How much does a hub weigh? The OP says a brake drum weighs about 40 lbs. I'm guessing the hub is also around 40 lbs - the hub-drum combo is heavy!!!

I pulled my drums off today and they weigh more than 40 pounds. I can carry 50lb sacks of feed like they’re nothing and these things weigh at least 80 pounds and it feels closer to 100. Not saying anyone is wrong but they feel a LOT heavier than 40lbs

Confusion over the weight of a "brake drum" goes all the way back to the very first post in this thread, about sixteen years ago:

A stripped brake drum may weigh 41 pounds, BUT . . .

With regard to the brake drum ASSEMBLIES - as they are pulled off the spindles (as you feel that sharp pain in your lower back) -

Front Wheel Hub and Drum Assembly ( about 65 individual parts, inc. bolts, washers, etc. ) - 83 pounds.
Rear Wheel Hub and Drum Assembly ( about 69 individual parts, inc. bolts, washers, etc. ) - 87 pounds.

Pulling the drum assemblies is a common task and there are lots of ways to reduce the risk of injury. Please post your suggestions/recommendations.

Thanks.

Straddle brake drum and use both hands to slide it off and lift it - one hand on the hub, one gripping the edge of the brake drum. Set it on a couple wood boards in front of the spindle so you keep it out of the dirt while you go get something to safely move the hub-drum assembly.

I grabbed a rear drum (because I have a pile of them!) and weighed it and it is actually 50lbs. I must have weighed a front years ago and they have a bit less material in the center.

I'll offer that we're using two different terms "Brake Drum," and "Brake Drum Assembly" interchangeably and that's causing the confusion.

I've seen the drum ( just the drum ) listed as 41 pounds in the past, but hadn't verified it. I just now looked it up:

1.) The front and rear drums are identical: NSN 2530-00-288-2968 or PN: 10896696. (TM 9-2320-361-24P / 2006 / Pages 0093 00, and 0094 00)

2.) The drum weight, "Est. Pack Weight," is listed under the NSN as 41.0000 lbs. (https://buyaircraftparts.com/part-number/3219t2022_00-288-2986)

The Brake Drum ASSEMBLY is a whole different critter. As mentioned in an earlier post, I carefully weighed the front and rear drum assemblies last summer and came up with 83 for the Front, and 87 for the Rear. We're using different scales so results may vary.

The only reason I even mentioned it is because, for those old guys among us, especially those of us who have to contend with bad backs, it's important to know that those ASSEMBLIES that have to be lifted and pulled off the spindles are pretty dang heavy. Be careful. Getting laid up with a herniated disk ain't no fun.

I didn't mean to start an argument about a few pounds one-way-or-the-other. If I did, I apologize. The important thing is to have a good idea of the weight so you can plan for it and not get hurt. 80 ± pounds is probably a pretty good ball park estimate.

The picture tie6044 posted ( above ) is a special case. The nuts and bolts are an indication that for a drum that was on the front, the brake drum adapter is still attached. If the drum is off the rear, both the brake drum adapter and the dirt deflector are still attached. That would account for the extra weight over the 41 pounds for a bare drum.

Stay safe!
