is it possible to replace actuators with pneumatic cylinders from 42080?

i forgot gear for rotating and after building and attaching superstructure it moves like zero friction. How to fix undercarriage gearbox easely? Other functions works perfectly, crane is mighty strong

this set is openly selling in Russia begining on sunday in the licensed Lego stores (mir-kubikov), got it, very neat B-model and any digital instructions is not avaliable now. For some reason slewing doesn`t work, stick with gear moves freely, only built undercarriage by now. Is spare parts are normal, or there is mistakes either in my work or in building instructions?
