Nope, just a center punch and the bell clamped down. I start with a smaller drill thru. Once I knew the hole was in the right spot i used the right size drill and then a tap.
With the tap i always go a full turn then half a turn back with plenty of oil. I even had to back out and clean the chips a few times. Just take your time and it will go smoothly |

Any tips on putting the stator back on the bell cap? I'm about to put it back together and test it soon, then I'll epoxy it once it's all checked out...

Already put it together before I had to run out of the house, this is a pic of the wind, not too bad for a first...I messed up one turn where the wire didn't get fully flat and it kinda off but it will work, minor detail for now...

Looks nice! carefull with that jumper wire passing close to the center:try bending it more outside, and if you have some insulation paper put a round piece on the holder before assembly

I cooled it in the freezer over night and put a socket inside the stator hole but big enough to sit on the bell cap, then I gently tapped it with a hammer steadily pushing it out until it came out all the way

I think he meant taking the bell off the motor, not the stator off the holder?

I think I might have messed up one of the bearings when I reinstalled or it's getting a little notchy so what bearings are you guys using?

Looks great! I think I will rewind my burned 460MX soon.
One noob question though. The original winding is 9T delta. A winding calculator is telling me I could wind it 9T Delta or 5T Wye. I wonder what's the practical side of these two. Thanks! |

Y will give you higher R. D is preferred if it gives you the KV spec you need.

I also find myself having to rewind my Scorpion 2221-10 3000KV after a lower bearing replacement.
While punching the bearing out it separated and left the outer race in the can. During the process of getting it out I somehow broke a wire on the motor. Might could have patched it but... nah! I'll just rewind it. I had to build a tool to get the stuck race out of the motor. Anyhow now I'm having one heck of a time getting the stator off the end plate. This guy is as tuff as I've ever seen. I finally have it tapped out about 4mm and stuck it back in the freezer. Nice work FusionSX00 as always.

We recently bought a new fridge so I can get them separated more easily

It was sort of one of those freak things really. It should have been so simple you know like many times before. Tear it down, throw a new bearing in, set the mesh and off to flying but it turned into a nightmare and cancled out what little of the weekend I had left to fly. I could have flown the 550 but I can't enjoy flying if my 450 is down. The bearing wasn't nearly toasted but had started to whine a little and I thought I better change it. It was bad bearing but might have lasted 200 more flights to complete failure. That particular bearing is not a pressed fit so I have to loc tite it in place.
