Order a replacement belt for your tape deck using the model number on the bottom or back of the component, then follow this tutorial to change out the old drive belt.
Unplug the cassette deck and unscrew the component cover by removing the screws on the bottom, back and sometimes the side of the tape deck.

Remove the old belt. The easiest way to do this is to use wire clippers or scissors, and simply cut the belt, then strip it off the motor and pulleys.

Reconnect all wires and any electronic components that were removed to replace the belt. Replace the component cover and plug in the tape deck.
