I have a SW36-13KA. My clutch is not engauging. I checked for power going to the clutch with a test light and got power. I would like to remove the clutch and bench test it. How do I remove the clutch bolt (it turns freely now and rotates the whole clutch)? If I put 12V to one of the clutch leads and ground the other it should engauge right? Thanks for your help .
