How to align outrunner shaft?

[leoms]

I have an outrunner which I took apart (to diagnose a problem, which turned out to be play between the shaft and bearings; I'll ask about that on a different thread). Before I put it back together I want to make sure the shaft is perfectly straight in the rotor. It slides into a holder which is not super loose but also not tight, it slides right in. Then there are two set screws. Pic attached.

Does anyone have insight into how to best test the shaft's alignment? If it's out of alignment, I can imagine carefully shimming or otherwise trying to tweak it, but the first step is checking, and I can't think how best to do it.

In your post you only attached one picture.


I hope this will help you.

Thanks for the tips. I already was at the point where I mounted the accessory to have a better grip to the whole thing, but nothing moved, pushing the the shaft against the ground did the trick. I made photos along the way to make the whole process more straight forward for others and for those...
