Just purchased a 2021 zforce 950 sport and am trying to install a stage 2 MSC clutch kit. Removed the left hand thread nut and bolt holding on the primary clutch, but It won't slide off the shaft. Every video I see online they just slide off due to spring pressure, but I can't get mine to budge. Any tips on getting it off? I tried tapping it but don't want to bang on it too hard to break it loose.
