There are several pages of the Workshop Manual deliniating disassembly and reassembly of the cluch pressure plate assembly. You may be interested in this if you intend to inspect or replace some worn parts. Otherwise this job may be a bit daunting or beyond the "courage" of most DIY home mechanics. Most people will leave this to a specialist, or just replace the assembly as a whole.

Rochester Clutch and Brake Co. (Ph: 585-232-3279) will refurbish your original Borg & Beck Clutch plate and disc and send it back like new for about $100. Balancing the unit will cost a bit more. Half or less price than more popular shops. As shipping and labor costs increase it may be more prudent just to buy a new one.
