Ideally you take the Primary clutch off with the proper clutch puller and install the new parts on the bench.
The clutch face is held on with 6 bolts and there's the spring in there that's compressed by the clutch face plate.
The weights are held in by a pin and nut. Simple to remove once the clutch face is removed or compressed securely. An Allen key and 3/8 wrench is required for this.
If you have never done it before you should have someone Show you how it's done or if it's only a 1 time change, have the shop do it.
It really only takes about 20-30 minutes at most by someone experienced at clutch work.
So the shop shouldn't charge more than an hours labour.
Sometimes the Drive or Primary clutch can be very stubborn to get off the crankshaft, and this definately needs someone who has experience with these tough to remove clutches.
For the Driven or Secondary Clutch:
You will need a compression tool to at least do the Secondary Clutch.
The Driven clutch has the helix and spring in it, the Helix bolts come off with a Torx head bit and they as well can sometimes be difficult to remove and require heat to avoid stripping the bolts.
The Spring is under a lot of pressure and this is where a compression tool is definately needed. There's a snap ring(need snap ring pliers) and that holds the rollers in which is above the spring.
