OK, a point to note for Skycaptain (given I said getting the bearings out is easy). Tonight I pulled my 5404 motor apart to replace the busted hall sensor. When I push the motor out, the bearing on the non wire side stayed stuck to the axle (on my 5303 it remained in the cover). I was worried that when I returned the stator into the hub, that I could have problems, as I presumed the bearing would be a tight fit into the cover, which can be a problem if it slams up when returning. So I removed the bearing from the axle, but I needed to use a gear puller to do it it was so stuck on. I thought I was being gentle, but I have now dented my bearings. They are nice bearings though, appear to be genuine SKS bearings.... But then when I went to put the bearing into the cover, it is so insanely tight fit, I think I will need to press it in with a piece of wood etc. Makes me realise I was damned either way, because if I had tried to return the stator with the magnet force, I think it would have got stuck as unless the bearing was perfectly lined up with the cover it would have jammed. Anyway, who knows.
To my question. Can anyone point me to a thread with a photo (or just confirm) how the wiring on the hall sensor should be? My understanding from when I was trying to do my 5303, was that if you were staring at the stator with the halls on top, the hall would have the "chiseled" face facing you (ie the flat part to the back, the shaped or chiseled face facing out), and the wiring would attach to the three legs from the top as (colour - eg yellow) then Black then Red from left to right. Is that correct? Obviously if someone can point me to a photo would be awesome. Obviously I tried to look when I removed the bad hall, but when removing it I hadn't fully heated out the epoxy, and it tore off leaving the three bare wires and I was unclear which was which (on the existing sensors there is too much epoxy to see). I just wanted to be sure before I went through the whole trauma of putting in the sensor.
I am a comical idiot at this hobby, if anyone could watch me in the garage they would think it was Homer Simpson trying to build a robot.
