hare pictures of the rear brake cams , as u can see it ran out of the shaft ,i saw there was a movement in the cam/shft area and when i pulled it towards the back the can stays but the shaft fell out .,now what? ill have to remove all the back wheels of my cars i have installed this part on and return them,

Oh for Pete's sake!
Why didn't the manufacturer pin the two pieces together? I would reassemble the shaft into the cam then drill and pin them together, hoping that the shaft is not hardened. Another thought is to weld a washer of appropriate size to the end of the shaft (after reassembling, of course) in order to retain the shaft in the cam; provided that there will be room between the washer and the inside of the brake drum.
My two cents worth. Bill

Poor repro part design, to have only a mechanical hold on such an important part. The Ford parts were one piece forged. Now sure a new forging die is out of sight....but still, the part should have the same or similar strength as a forged parts.

Worthless design.

Similar occurrence with the repro spring hangers, the splined mechanical attachment just slipped away. On this one, happened on my poor install, as the wood block I was using to spread the spring shackle and spring go away, caused the tip, and the repro shackle came apart on bending.




But later I found two loose, as the spring action on the shackle is a bouncing and the mechanical splines just wore down, and the shackle was loose.

So, only Ford forged one-piece parts for me, no repro mechanical only splined and press-fit together pieces!

Is the cam hole & splines in good shape? that's the deciding factor in attempting a repair on what you've got. The shaft looks OK in the pics. Next problem, as Bill states, is it a hardened shaft. a little drill experiment should clear that up though I can't see it being soft. If it's drillable my first choice would be through the thin end of the cam to avoid any interference with the shoes. I'd go for a threaded hole myself then cutting off the bolt head & peening it over. Straight into the shaft with a washer & bolt is another option.

Mark the pieces before you repair, as the splined shaft is indexed to the brake shoe cam, you don't want the two out of alignment, or else the lever will be in the wrong spot.

Would be better to locate some originals, NOS are nice :-)

Of course the real solution is for all you guys who like to complain about the low grade reproduction parts is to actually MAKE some quality reproduction parts. OH wait!! The average T guy won't pay for quality!!

Bob, the cams on my '27 do not have the big washer on them like the one in the pictures.

Were different types available for the 26-27?

Amen Les, I am glad someone is reproducing parts. I can take the time to tweak things if needed, can't do that if nothing is out there. Would be nice to have a stock of nos parts but that is not possible for most people. KGB

Eric

That style with the flange is perhaps early, check out this previous thread:

Please let me know who the vendor is. I was about to buy a pair. You can send me an email from my profile. I really do not want this to happen to me.

Keith
10 minutes with a torch and silver solder and those cams would never come apart
Same thing with the shackles

Thanks Dan.

Looks pretty clear - cam with the large washer is early 26.

I got my new cams and they do not have the washer. My problem is the bushings I ordered and received are .010 oversize to the bore in the end plate on the axle. The new bushings are split but the first one I tried to push in opened up at the split and now is distorted and no good. Anyone have this issue and maybe knows where to get one that fits? It is a 26/27 and the hole in the end plate measures .864". The hole is clean and smooth as the old bushing just cam out.
Thanks
