You usually won't need that tool, unless you are removing the basket assembly.
Pull off your clutch cover, may have to drain oil, You will see bolts with springs behind them, loosen them all a little bit at a time until they are free of the spring tension. Remove the pressure plate, and your clutch is behind it. Make sure the order, stays the same. There are 2 types of plates, steels, and friction plates. Some have "O" rings that are nestled in there too, and there may be a type of wave washer at the end of the stack. Inspect the basket for any deep grooves worn into it, that would allow the clutch to hang up. It sounds complicated, but it's not, once you see what's in there. BTW use a TORQUE WRENCH when putting the springs and bolts back in. I can't tell you how many I had to drill out for guys who didn't!
Typical torque spec is around 7 to 8 ft/lbs
