What hub/drum assy do I have here?

Thanks,

Seems I need to get a resizing application.

Will send you the pic.

Thanks again,
Mike

Yes, the file you sent me was 3.27 MB and the maximum size you can post (per the limits listed in the pop-up menu). This is 120KB. What computer are you using, or are you doing everything on your phone? I also cropped the photo removing the space at the bottom and top.

Ford made two types of 12" X 5" on 5.5" lug pattern drums from 1940 thru 1948. The earlier drums were wide 5 pattern. The earlier ones of the two types had the hub mounted on the inside of the drum and the later ones had the hub on the outside of the drum. It certainly could be the inny type or perhaps an aftermarket replacement.

A photo may not tell the whole story. Measurements and characteristics say more than a photo. For example, I can't tell the drum braking surface diameter or the lug pattern size from the photo. An 11" braking surface drum would be later if the pattern is 5" on 5.5".
 
First, thanks to jseery for posting the pic for me


The BP is 5 on 5.5. I ran a tape on the other side w/o a hub that has the shoes on it, and appears it’s for a 12 inch hub. The shoes are 1 3/4 inches wide.

Thanks.

I figured out last night reading another members reply about editing the pic in Paint, it worked, but seems since I was at work there was a security issue in posting the file. I was on the secure network, probably what the issue was there. The member also posted how to make the pic smaller on my phone, but for some reason I can’t download an app on it.

And again, I thank you for your help!
 
It's what I'd call a "40" hub. Drum fits over the hub. (Hub is on the inside).

Brakes are 12x1.75"

Later had the hub on the outside but off the top of my head I'm not sure where the switch point is.

As a point of interest, the hubs/drums as an assembly are interchangeable for any year 1939 to 1948

Mart.
 
It looks like this 1940 Ford front drum.

Your drum pictured below is what I believe to be an
"aftermarket replacement" drum/hub assembly for 1940 and '41, like in 19Fordy's pictures above this post.

An original '40-'41 drum has these bumps or scallops like in the pic below. DD

Thanks V8 for that tid bit of info.

I always thought the OEM brake drums were smooth like the ones that were on my 40 in 1963. Here is a photo of that same drum/hub assembly. Can you make out the part number. The Ford parts book shows Ford Part Number 01A-1105-A for 1940-41 Ford. Cost was $6.25 for "Hub-Front & Drum". Gee, that was a lot of money in 1940.

The Hub-Rear & Drum shows Ford Part # 01A-1115-A and cost $7.50 in 1940.

Hey Jim....You know, you MAY have a point there. I said "I BELIEVE...", which actually means "WTH do I REALLY know?" You surely know that "01A" means "1940-First Issue". The "-A" means "Passenger Car". The "1106" is Ford language for "front hub/drum ASSEMBLY"...you could NOT buy a drum from Ford separately. The "-A2" at the end means some sort of update or change. So, with that type of part number forged into that hub flange, it is likely a Ford replacement assembly, or merely a later production assembly used on some '40 or '41 cars and light pick-ups. But remember...what do I know? DD
 
I appreciate all the replies, assuming an aftermarket assy, and trying to achieve symmetry, is my best bet for a 40-41 assy?

YES! Boling Bros. also have the only quality, 'stock-like' drums available. Do NOT use the Speedway drums which look similar to the Boling Bros. drums. They have had several problems. Boling drums replace the same way as that repro Buick drum. Replace the studs by reaming for .600" Dorman 610-234 studs, and voila! Same deal....contact Gary at Cornhuskers. DD

Thanks,

Issue I have is the other side is without the hub/drum assy, just a spindle and backing plate and brake hardware.

I have an hydraulic braked axle out back, but hate to pull it apart as I can't get it in and out of the weather.

SO looks like I'm in the hunt for a 40/41 hub/drum assy.

Sure wish the swaps would open soon;)
