How to Replace the Belts on a Cassette Tape Player

Updated July 19, 2017

The belt on a cassette player is an essential part. Driven by the motor, the belt rotates the spindle shaft and the cassette's cogs so that the audio tape inside the cassette is dragged across the tape heads, which enables the music to be played through your stereo. These belts can wear out with time, causing them to break or loosen so that the speed of the cassette player is affected. Replacing these belts is not too difficult once you know how.

Write down the make and model number of your cassette deck, which should be printed on the back panel. Purchase a replacement belt from your local electronic store using this information.

Unplug your tape deck. Use a screwdriver to remove the screws from the outer casing of your cassette deck and lift off the cover.

Look for the black rubber drive belt, which should be located near the front of the machine. Remember, or write down, the path of the belt around the different component in the player. You will need to position the replacement belt in the same way.

Remove the old belt by gently stretching it away from the components of the tape deck and lifting it off. Alternatively, if the belt is broken or stuck, use a pair of tweezers to avoid touching any other parts of the deck.

Install the replacement belt, making sure that it fits round the cogs and wheels in the same manner as the old one. Make sure the belt sits in the outer grooves of the wheels.

Plug your cassette player back in and press "Play" to make sure that the right-hand cog is moving counter-clockwise. Press "Stop" then "Rewind" to make sure that the left-hand cog rotates clockwise. Unplug your cassette deck if this is correct, reposition the outer casing and, using a screwdriver, replace the screws.


If these procedures don't fix your cassette deck, then there is probably a more serious problem. It is not recommended that you tackle these problems alone. Sometimes it's best to take it to a local electronic repair store and have them look at it.


Always ensure that your cassette deck is unplugged while you are working on it. Ensure that all tools are removed from the interior of the cassette player before plugging it back in and testing it.
