OK looking for some advice. I am attempting to take off the back CVT cover plate and that entails removing both clutches. I got the proper tools for the clutch removal and had no problem getting both the clutches off except for the back sheave of the primary clutch. I just purchased the clutch puller for that, but when I screw it in and it bottoms out using my air wrench is will not screw in any further to release the back sheave. I don’t want to damage anything, is it supposed to be that hard on there? Any tips?
