Magnavox FD 204 CD Player

Hi. My name is Mark. I have been signed up for this site for a while, but have never posted. I found one of these old, 20 Pound CD Players tonight in my local Thrift Store. It works great, but the drawer stops just a little short of closing completely. I have to push it in about 3/8's of an inch to get it to close. It sounds like it continues to run like it is trying to close, and will just open up again without my assistance. I guess it could be an old drive belt. The belt looks fine to me. But it could be worn, and stretched. I have never replaced a CD Player belt. Any ideas? Anybody know the belt size? Or I guess it could be the motor. Any insight is appreciated.
