Turn table not working and loud noise

I followed the directions posted by others - they were perfect. This was a very easy process. The screws on the motor were hard to take off because they were put on at the factory with equipment is my guess. But the process was very easy. The turn table is working. I still have the noise but now realize that is from the magntron fan, which I am not going to replace given the age of the microwave. At least my food is heated evenly with the table turning and I can live with the noise until I see the price I want to pay for a replacement microwave. Thanks all!!!
