I Fixed All the Little Things Wrong with My Coda and Broke One Big Thing

Would just big washers work to cover the gap so you could still bolt it in and the washers will hold it up

In the video, at 1:15 I can see the left side inner small Jubilee clip "that's not supposed to move like that" etc. But immediately after, with the same camera view, at 1:24 "lets tighten these motor mount bolts" the large clip has become visible and the cv boot is visibly compressed. What happened inbetween these two shots?

Robert, Want to help me ev swap a Fiat 124? LOL

Wouldn't this all have been caused by putting the wrong shafts on the wrong sides?

Robert, so sorry you are having so much trouble with your CODA, reminds me of my '88 Jetta, the transmision basically split in half, then again I did beat the snot out of it. I see extensive dismantling of the gearbox and aluminum welding in your future, not for the faint of heart. Once you sort out the repairs you do need to invest in a torque wrench though. Wheel bearings like in your CODA and other vehicles are of the double row / angular contact type with split inner race. When you assemble the half shaft (or tighten the nut on the rear drums) you are bringing the two halves of the bearing together setting the preload (not unlike the bearing preload on machine tool spindles) This is critical to their proper function and long life. You also need to make sure the spline shaft does indeed tighten up the bearings (and not just run out of thread) for reasons mentioned above, and make sure any spacers are properly installed. If spacers are needed they should be of sufficient strength / quality as not to "squash" under the preload. And lastly, don't forget the dust shields!!

Hi Robert, regarding broken piece in door lock - it looks like it can be easily modelled and 3D printed. Or maybe milled from aluminiminum?

Ugh I can't stand messing with CVs, just make everything RWD with a prop shaft!

Hi Robert! As a long time mechanic I can tell you "Stuff Happens." Take a break, then pull it out and assess the damage. Since it is so recent you can probably find a welder or machine shop that can reattach the bosses. A good welder like Justin at "The Fabrication Series" can do this with their eyes closed (not that you'd want them to.) Maybe there is a colab in this? Worst case, you will have to separate the side(s) that broke so they can weld on it(them) without damaging the internals. Worst worst case you contact the folks at EVTV Motor Verks and ask if they still have any CODA gearboxes. Or if they can sell you a gearbox case. I don't know if you are aware, the non-CODA UQM motors, although the same part number, will not work in a CODA. It's got something to do with special coding in the software. Good luck! p.s. If you need help please don't hesitate to DM me.

They make really big zip ties.

I guess the gearbox isn't just one they used in other cars too? Maybe you can get the studs welded? (don't know what material, but I'm guessing aluminium?)
