Easy repair.
the part arrived and was easy to replace. just removed the plastic cover and pulled the top baring with a battery terminal puller, broke the glue holding the plastic ring on and slowly worked it up with a brass driver till i could use the battery terminal puller on it. slid the new magnet ring on and the bearing after it. runs just as well as it did before.

Parts Used
To replace magnet ring, the bearing 330003-09 must be removed. To do this I had to completely dismantle the router and make a slotted steel plate to slip behind the bearing while carefully hammering the end of the shaft with a brass drift.
After releasing the springs on the bushes and the earthing wire screw the whole brush ring and field assembly can be pressed out of the case with steady force; then the plastic field case. Now remove the big clamp nut and press the armature assembly out of the larger bearing.
Remove bearing 330003-09 and cut off the plastic remains of the old magnet ring. Glue new magnet ring into position with 2-part epoxy. Re-assemble armature in case and then very carefully tap bearing down to just touch the magnet ring. ( First time I broke the new magnet ring and damaged the bearing getting it off again) Now re-assembled and working fine.

Parts Used
Used wheel puller to pull the Bearing of to allow access to top shaft under yellow plastic Dewalt housing. once bearing was removed I made sure to remove any errant pieces left behind by the shattered magnet ring of which I discovered a small ring like piece still on the shaft that looked like it belonged there but upon careful inspection and referencing the parts diagram I realized that it was a remnant of the magnet ring alignment ridge made of plastic i discarded that and installed the new piece. reseated the bearing and put together unfortunately the excessive sparking that called attention to the broken ring was still occurring. I disassembled again and noted that there was some green discoloration on the copper commutator contacts of the motor shaft itself. Indicating to me that corrosion was the culprit of the sparking. I tried mitigate the damage with progressive grits of sand paper starting with 800 grit up to 2000 grit but unfortunately I have to order a new motor shaft. Its a sin because even though Ive had the dewalt router for a number of years (kept in its case with the 3 bases) I have about a total use of probably an hour on it ill update after repairing the shaft hopefully dewalt will cover it they seem to be good that way from what i have seen around the internet. details to follow! as far as my purchase I am happy and the part arrived quickly!!!!!

There are some informative videos that walk through the process quite well. Watch them.
Router will still work without the magnetic ring, but at max rpm. Make sure to pull the motor out and remove all magnet shards and debris and put it back together. It's not ideal but it can get a job done while waiting for parts to arrive.
The new magnet fit well and installed easily, remember to epoxy the ring to the shaft and let it cure before use.
I noticed that my soft start isn't quite as soft as it was with the original magnet but that's just an observation, I don't think that it'll be an issue.

1. Removed the End Cap.
2. Carefully searched for pieces of the broken Magnet Ring.
3. I used the Gear/Ball Bearing Puller to removed the Ball Bearing (Is supposed that the Puller help to remove the Ball Bearing without damage it, but that wasn't my case, luckily I bought also a replacement of the ball bearing).
4. I found the inner piece/ring of the magnet ring still mounted, so, I used a flat head screw driver to remove it, this helped me to see what is the right side to put in place the new one.
5. To put in place the new ball bearing I have used a hammer and a socket with the same size of the inner race of the bearing.
6. Then placed again the End Cap.
