This is the Quote from Thud on motor disassembly... I took pics just to replace the missing ones, but not all of them came out... here are the ones I have.. they DO show the clip and spacer under the cap, something I was unable to find pictures of online... If a mod could copy this to the front page, it would be nice.
#1 inspect the shaft for any nicks or bump that would impead the removal through the bearings.
#2 remove the 4 inside bolt circle 5mm cap head bolts & remove the end cap (its a light press fit & pops off easily)
once removed your motor looks like this: (notice the yellow Phase wire was actually shorting to the end plate..this is a brand new never run motor!)
#3 remove the circlip & spacer...& the 4 screws holding the skirt bearing to the can. use a proper fitting screwdriver (allen key) as the screws are kinda soft.
#4 Using a plastic faced hammer, gently tap the end of the shaft a few times, this will loosen the skirt bearing from the can, once free we are ready to press the can off the motor.
#5 press the magnet can out of the bearing tube. You see I am using the stock motor mount to gain some purchase, I use a singe bolt from the end cap. My technique is to hold the motor mount with my index fingers & press the shaft out with my thumbs.If the shaft is properly smooth, it will slide right out.
BE CAREFUL the magnets are very strong & if you change your grip you can potentially receive a nasty pinch.
You see I had a slight burr on the end of the shaft & its hanging in the bearing race. I just installed a 4mm cap head screw & tapped it through gently.
Now you can tap the skirt bearing off the bearing tube. Use gentle taps & apply preasure 180 degrees to the bearing & it will pop right off. Next remove the bearings from the tube, I use a length of 10mm rod with a very square face on it, reach through one end to catch the inside race of a bearing. Now alternate tap's in 180 degree incremants & the bearing should slide out also.
congrats. You have diassasembled your motor & it looks like this.
