How to unscrew clutch crank nut

[Geeky]

I am not able to unscrew the crank after trying for hours. I have a socket wrench that fits the head but when i rotate the clutch plate rotates. I can stop the clutch plate front from rotating but not what is behind.

I used a wrench that fit the nut and a hammer to tap the other end of the wrench, the effect is you wanna put enough torque on the nut but not enough to rotate the entire clutch

Thanks mkpctv. I did that and it worked. I oiled the nut, tap hammer, and then someone holding the clutch with pipe wrench.

Ive never seen that type of crank bolt before. Is that a stud built in the crank and a nut?
