'68 Juice Brake Shoes

My 2c
41650-63 Backing plate 63–66, stamped outside with “Bendix 300790”, has cup inside surrounding axle, for star hub.

Backing plate 67-72 stamped outside with “Bendix 322922”, has no cup inside surrounding axle, for midstar hub. (bearing in drum)

EDIT based on Panhead-kicker's EDIT

H-D part number unchanged?, as MoCo were wont to do

Ok, will Mongrel or Panhead kicker tell me about the size of the hole in their mid star backing plate. In either of your pictures it looks like an insert reduces the hole size because the pictures definitely show it smaller, which makes sense for the smaller oddball size of the mid star axle. The V-twin lists one backing plate from 63-72 and the picture shows my swap meet backing plate, with the grease cup, and the larger hole. At some point, I want to replace my backing plate but don’t want to tear it all down and not have the correct plate or at least one that I can make work.

My stop bolt, with the double nuts, is a fix of my own design. The large stud had the threads ruined and a tapped hole in the middle. The frame bracket has a large hole that surrounds the stripped stock stud, spacers to the backing plate, and a stud and washer to just hold the large stud in place in the frame. It works well but when the shoes need doing, soon, I would like to set it up better.

I'll get you a measurement this afternoon.

The hole in the backing plate is the same size as a hole in a rigid plate and early Juice plate. The stub axles for all are the same OD, regardless of other features on them.

It's back on the bike, so unfortunately I can't get a measurement for you.

1" axle hole, in the side plate without the cupped area

You may want to post pics of your parts.
Heres a pic of 69 side plate and shoes

I apologize to all, and sorry for the confusion.
I have looked back through my info and determined the side plate picture I previously posted with the cupped area is from my 64, not 69!
Below is my 69 side plate, note it is Not cupped around the axle hole. "Bendix 322922"

So the Bendix 300790 is the earlier plate. It appears that I have the wrong plate for 1968, although it looks like the pictures posted here of the later plate, and it goes together fine except for the clips, which took a bit of persuasion to install. I don't understand how the 322922 plate would change that situation, but I guess if I get one I'll find out. Panhead_Kicker, about how wide are the shoes for your '69?

Jim,
In your pic in first post, the edge of cup appears it may have been rubbing on hub?

Nifty, you may be referring to Panhead_Kicker's first picture in thread. My plate is the third picture, I believe (without going back to count). In any case I adjusted the two 3/8" square shoe adjusters with the drive chain removed to get a better feel for the wheel's resistance to turning. With the shoes backed off and no drive chain the wheel will spin freely for many revolutions and I don't feel or hear and scraping.

This bike has been full of surprises, so that wouldn't be out of the question. It looks like I have a 1970 - up battery side cover, too, but that's another story. Fender tips are 1966, but I like them so they'll stay for now.

I'm gonna go out on a limb here and speculate that since our beloved MoCo never throws anything away, and the absence of the later grease catching cup was, no doubt, determined to be of little, or no, consequence, they simply used up what ever backing plate presented itself at the time of assembly. Simply put, they used what ever was handy to assemble a motorcycle, and let the service personnel out in the field deal with it when necessary, eh?
....RooDog....

[Andygears]

Since it seems the two later backers are somewhat interchangeable, I guess the swap meet plate I got will work to replace mine. Thanks to all.

...Panhead_Kicker, about how wide are the shoes for your '69?

here's a set of standard size 41801-63. Narrow one is ~1.5 , wider is ~ 1.75. Both shoes are the same width of course, only the lining is different sized.
