If you are talking about the arm on the engine I believe you need the cable to move it because the pressure exerted by the clutch springs are more than you can do with your hand. I am not exactly sure so dont quote me.
I dont know if the service manual has the arm movement freeplay in it but i would check to make sure that is within spec. If not you would prolly have to remove clutches for a deeper inspection.
Anyone else familiar with this problem?
