Step 2

  • Using a flat edge (such as a spudger or a flathead screwdriver) pry the C-clamp from the center spindle by wedging the flat edge between the spindle and the C-clamp.
  • The C-clamp may pop off unexpectedly, so be careful it doesn’t fall somewhere hard to reach.
  • The C-clamp his what holds the platter in place. With it removed, you can now et under the platter.

Step 3

  • The drive-belt will be found either around the bottom of the platter or around the motor.
  • If the drive-belt is broken it will need to be replaced. If it is loose, you can simply re-secure it.

Step 4

  • To replace the belt, wrap it around the inner circle of the bottom of the platter. Then stretch the belt around one of the two pegs found near the outer edge of the bottom of the platter.
  • This will be a snug fit, so be careful not to snap the rubber belt!

followed instructions multiple times—hear and see that the drive motor is spinning but platter is not— what’s wrong

The belt is fine and placed correctly but the record speed (33 and 1/3) is off. Spins too fast.

Suggestions?

What is the size of the c-clip / c-clamp? I’d like to replace one.
