If you're still listening to vinyl records on a belt-driven turntable such as the Pioneer PL-514, then you probably understand the importance of turntable maintenance. Over time, the internal components such as the drive belt can break or become damaged, so it's always a good idea to periodically replace parts. If you need to replace the belt on your turntable, you'll be pleased to find that the process is relatively straightforward and shouldn't take up very much of your time.
Unplug the power cable from its outlet, lift the tone arm off the turntable platter and set it to its resting position on the side of the turntable.
Lift the rubber pad off the turntable platter and then lift the platter straight off the turntable by the two access holes on either side of it.
Turn the platter upside down and locate the lip on the inside of the platter. Fit your turntable belt around the lip, making sure there are no kinks or twists in the belt.
Replace the platter on the turntable and locate the thin metal pulley through one of the access holes. Use your fingers to pull one side of the belt away from the lip and place it around the pulley.
Rotate your platter a few revolutions to make sure the belt catches the pulley, and you are done.
