Since you know how to open the vacuum and have already done some work on the motor, you seem to have enought knowledge to change the motor.
Go to a local vacuum shop, ask how much they sell the motor for, it maybe about $100 or so. If you do the labor,you will have vacuum that will last another 10-15 years. If you buy a $100 vacuum it will last 2 years and it will not clean as well as your 'rebuilt' electrolux.
Send me a note and I will help you find a local shop if you would like...danddvacuum@comcast.net
