Good quality UK sourced twin B profile V belt pulleys which utilise the taper lock bush method of shaft mounting.

These are the same profile as used on the original Lister Start-O-Matic sets, so if you are replacing your Start-O-Matic alternator/pulley then this is an ideal replacement that will allow you to continue using the original size V belts and the grooves in your solid flywheel.

Simply select the correct size taper lock bush to match the shaft size that you intend to mount the pulley on, couldn’t be simpler!
