You will need a pole puller to disassemble the flywheel of the generator as it is fixed with relatively high torque as a cone connection. It is best to measure the diameter of the thread yourself beforehand. Of course, we also carry pullers with other thread diameters and slopes. Definitely suitable for models in the list with Piaggio 125/150 and 180 cc two-stroke engine or Vespa Classic Scooter. Thread: 28 x 1 mm. Vespa: almost all models from 50 to 200 cc had pole wheels with the M28 x 1 mm thread, where this puller fits. If necessary, please measure beforehand...
