Motor belts are pretty essential - most elderly machines will run much better for a replacement.
If you look inside and there's lots of black rubber debris, then it's time..

Take the old one out and look at it - there are 4 basic types below, and one or another should do the trick.
Most experts dislike the rubber kind, as they can strain the motor if too tightly set up. All machines with a drive belt will have an adjustment somewhere to make the belt happy - it should not be loose enough to slip, or too tight - the general rule is that the belt should have about 3/8 inch / 1 cm of sideways movement for best results...

These belts are all new or in very good condition, please ensure that you have the right length for your machine. Lengths are the whole way round, on the outside, widths tend to be about 6mm / 1/4 inch

Here is a tutorial - Instructions for measuring and fitting a drive belt

Please note the belt lengths can vary even in one 'family' of machines, for example not all Singer 300 series machines use the same size belts! Page reorganised so belts are in order by length 13th February 2018
