Aiwa AD F990 problem

I have an Aiwa AD F990 that I purchased new in 1984. It has been in storage for 18+ years. I recently checked it out and found the belts had melted so I cleaned it up and installed new belts. Now, when trying to play a tape it will not take up the tape and stops on it's own after approximately 10 seconds. Any suggestions? I'm thinking that after so long being in storage that I will try to degrease/re-grease. I have a service manual but it isn't very informative as to what type of oil to use and where. I would appreciate any help. I'm not an audio technician but am quite mechanically inclined so I'm not averse to performing any maintenance myself.

Thanks in advance for any info...
