Need help quick... i just installed a spec stage 2+ clutch and the f'er won't release... i didnt measure the throw out bearing sleeve height/length but i think that is my issue... (clutch that came out was os giken twin plate which i know use a different size t.o.b. sleeve and bearing) i installed the t.o.b. which came with the clutch kit but like i said now it doesnt release the clutch off the pressure plate. I never opened the hydraulic circuit so it shouldnt have air in the system... ps i went and bought a New/used t.o.b./release sleeve from drift bitz yesterday but from my measurements it seems like it is ~18mm from fork tabs to base of bearing and in the parts manual it says its a part number 30501-k0404 which is 24mm... can anyone please confirm that their sleeve is 18mm for a normal single plate system? I just dont want to drop the tranny again and again.... thanks in advance!!
