We have replacement drive belts available in popular sizes to fit many hi-fi turntables and other diverse units; eg tape recorders, cassette decks, Walkman, CD drives, models and toys.
For most Japanese decks (full
platter):
Remove the rubber mat and lift off the platter (most hubs just lift off, some require the removal of a circlip at the
spindle). Turn the platter over and measure the circumference of
the hub (red
line in the photo). The belt needs to be tight enough to hold on the
inner hub
with minimal stretching so deduct 5 - 10mm from the circumference to
calculate the right length.
Fit the belt on the hub and replace the hub on the spindle. Rotate the
hub until one of the inspection holes is above the motor pulley. Grasp
the belt and hook it over the pulley and through the speed changer
mechanism (this stretch gives the belt the correct drive tension). Check
that the deck runs with no fouling, replace the mat and you're ready.
For
a transcription turntable (split platter):
Remove the rubber/felt mat and lift off only the outer ring section of the platter.
Use a piece of string to measure the total
distance round the hub and motor.
Then deduct 4 to 6% (typically 20-30mm) to give the correct drive tension.~
Fit the belt on the hub and replace the outer platter
upside down to
check that the deck runs with no fouling. Then turn the platter the
right way up, replace the mat and you're ready.
If
you still have the old belt:
This is the least accurate way to replace your belt and is not
recommended.
When measuring an old belt, remember it has certainly stretched with age
so you will need to replace it with a slightly smaller one. The problem is
that there is no way of knowing how much it has stretched.
If you are unable to measure your hub (red
line in the photo)
circumference, measure the diameter and use the table above, which uses
the equation: C (circumference) = Pi x D (diameter).
Pi = 3.141592 (abbreviated).
