clutch won't dissengage

[Rancher2005]

my buddy just replaced the fibers, plates and springs in his clutch on his 02 warrior. He tells me that it won't dissengage. It will go but he can't shift. I don't know any more details than that but he adjusted the new cable many times already. Any suggestions as to what the problem may be.

p.s. it's not a slipper clutch
