a new clutch appears to be available:The procedures, in general, for A/C clutch removal, usually require a puller. I would also make sure you can acquire a new clutch or at least the clutch bearing which may also require special tools to r & r the bearing once removed from the compressor shaft. Usually a good idea to replace the compressor seal as well. Because of the extra labor, most shops replace the entire compressor unit that includes a new clutch. Probably the least expensive way is to source a used compressor with a clutch and take your chances that this compressor won't leak once installed and charged with R-134A refrigerant.
