Hi Jason,
If the outer cover is stuck or jammed, you can set up a puller as shown in the photo. (Obviously remove the cover screws and crankshaft circlip first)

Once the main motor bearing is noisy, it is destroying itself. When it collapses the ball bearings come out the bearing and start running in between the cover and the main motor drive gear. The damage is fairly catastrophic. The problem comes when trying to fit the new bearing. It will not seat square, or at the right depth.

As for your broken lugs. I have tried different specialist aluminium adhesives on these, with little success. The torque loading on these lugs is particularly high and with two broken, you stand little chance of fixing them. Don't be tempted to tig weld them with the circuit board attached either.
The good news is that I do have casings and enough second hand parts to get you going again ;) Contact me at peter.collard@performancelinebearings.com
The bearing looks like this. Thanks for the reply.

A little off topic or maybe not...

What is a complete Bosch CX performance, brand new with zero km worth with all the bits including 400 Wh battery?
Good Question? People definitely don't want to pay top dollar because the motor is programmed for the bike it was originally fitted to. Not that it won't work, but it will have the original bikes wheel size and name. The wheel size can be offset by a Nyon controller but no others. I guess you will also be selling with no warranty?
People are also very sceptical of batteries, they will want assurance of how it was stored, what charge it had and what temperature etc. And it also depends on the country you are selling to, as prices for new motors seem to vary wildly!
Personally, I would say, in the UK £450 for the motor and £400 - £450 for the battery if you're lucky.

I am looking at a cargo trike and I don't want the motor supplied so it would be removed from a brand new bike, battery in delivered storage voltages state with zero charges on the clock etc etc.

I do want a 48v Bafang with PAS, not a torque sensor, double chainwheel and a 1.5-2 kW battery. Your estimate puts me very close to that being a zero sum swap over!
