in the uruial way changin- the speed in v-belt pivl lea tn,,isrions it is necessary to shift the belt rorm one v-bolt pulley to another, being of the different dizn~otocr in. the c-1se of' multi- stepped cone pulley; or ,,nother wyby havinp a, split pulley it is possible to h ,foa working functional diameter for the belt by insertin- or re~aoving bushes respective spacinn' washers between M0~r iairs of the pulley to adjust their distance within c~a'bain lim~itations.
