HELP! Windshield wiper crank arm came out ! I took it all apart - motor good but....

So at 79K miles my 2014 Equus Signature with Hermes light addition (love that look- and I did it myself- I posted pics b4-but I digress) had a problem while driving in rain- the wipers stopped!!! After arriving at my home in the garage, I took it all apart- wiper arms- all the plastic covers off, the cowl off and took out entire wiper blade motor arm components- I dis assembled the motor and transmission and bushing brushes inside to check all is good- cog wheel inside transmission also good but I rotated it to the other side which has no wear- re assembled. None of these things were the issue- the issue was the short control arm connection to the assembly- but the iron like black cog wheel bolt connects to the aluminum thread also cog like- but the there is no carter pin- and not enough room to try to bolt anything on - what to do to make up the space? I used JB Weld for metal- I will supply pictures-
I read older Genesis owners have recall on motor for wipers- called Hyundai about Equus- no dice they said no recall.... good thing I'm handy- the total price for the entire assembly is over $1K which includes new motor and arms but not the wiper blade arms- the only thing that failed is the weakest link - this iron bolt which connects to a short aluminum arm and you need to get both assembly and motor for both to work they do not sell the two pieces separate and used ones will be worn out most likely giving similar problems- like I said I will post pictures.... all is better now thanks to JB Weld and being patient and handy.... hope this helps others.

Looking forward to photos.

This was the weekest link under the assembly - no cotter pin, no bolt, nothing to grab on to except a cog like wheel impression on the iron shaft and a reverse cut out of cog wheel on aluminum piece as shown

Nice job!

JB Weld fail- I wonder if anyone knows if a cotter pin or similar pin ties the iron groved arm of the motor to the aluminum assembly as seen here- I am trying JB weld one more time but longer dry time - will keep informed - please feel free to chime in with ideas- there is literately no room for a bolt- I may need to drill a hole in motor shaft and make a bolt fit - absolutely maddening !

.... and used ones will be worn out most likely giving similar problems...

I feel like there is no epoxy or glue that is going to resolve this for more that a short period of time. You could drill the shaft and put a pin through, but it doesn't look like the aluminum part leaves room for that.
My suggestion is to try and find a used one that hasn't failed yet, and use the epoxy to reinforce it to keep it from failing soon.

Of course, if you have access to a machine shop, maybe you could get a copy of the aluminum part made out of a more suitable metal.

The JB Weld is still holding - next I would do is drill a hole in the shaft arm and put a screw and bolt- if JB Fails wihich I am sure it will one day or another- but for now it works fine
