It worked beautifully for about three years, then the circlip came off. I couldn't get it back on myself so ended up getting the LBS to do it. A few months later it came off again, repeat trip to LBS. This was followed by the circlip coming off every few months, always when I was at least a couple of miles from home. The LBS fitted a new circlip in the hope this would resolve the problem, it didn't.

It has come off again this evening leaving me with a 30 minute walk home. I have perfected the art of putting it back on with the aid of a flat screwdriver, but when I reattach the motor unit, the gears are all out of sync. It makes no difference how carefully I align the red dots and fit the motor unit so it is correctly aligned, every time I can't shift from 1 to 2 without it jumping to 4, which is not actually 4. Yet another trip to the LBS beckons.

What the hell am I doing wrong?

It is getting to the point where I am realising the circlip method of holding the sprocket on is not up to the job, and I am seriously considering throwing the damned thing away and getting a Rohloff. The only solution I can see is to solder it in place, which will work until I want to replace the sprocket.

It seems like soldering it on would be no worse than throwing it away and
getting a Rohloff; you might even succeed in unsoldering it at a later
date...

Soldering a pice of solid wire or small plate across the jaw would
both be easier, and make that easier. My guess is that the groove
was not up to the job (metal too soft or angle too shallow), and
that's the cause.

I found out from the LBS that they did apply solder last time they sorted it out for me, but that seems to have failed. Electrical solder is very soft so maybe not up to the job. The man at the LBS said he will try to think of another method. The problem is the clearance between the circlip and the motor unit is very small, so there is no room to wrap a sturdy piece of wire around the circlip to hold it on.
