is it really neccasary to torque the secondary pulley on re-installation for proper deflection or is tight with impact ok? i cannot figure out a way to hold secondary while trying to turn with torque wrench without using special tool, someone said in previous post about using zip ties but i dunno how they used those. I watched a you tube video while back and seems to me installer just tightened it with impact and video was pretty good quality so i assume guy new what he was doin but maybe there was a part left out when he torqued both pulley's. I dont understand how this could affect deflection but i am not a clutch expert, this is my first time in one. Input please!!!!!!
