The rubber clutch appears to be out on this shredder. Am trying to figure out how to remove it. I have removed the top of the gear housing and snap ring on the shaft. Also the 4 bolts holding the bearing in place. I thought doing so would allow the shaft to slide out but that doesn't work. Trying to find a shop manual that might tell me how to proceed. Am also wondering if this clutch alone can be replaced instead of the entire assembly.
