Hi I know this has been done over and over, but I am having troubles determining what the torque limiter is in the 04 upgrade... or at least what it does. which is it in the pic below? I think that I will need to replace my "one way" clutch, but do I really need to get the 04 upgrade as well? The 2nd idler (part 10) does not spin both ways by hand. I can spin it one way freely and push it with a flat screwdriver the other way which seems to rotate the flywheel. With the idler gear in (parts 4,5,and 6) but with the cover off it will not spin the flywheel when I hit the button, It just seems to grind. I am seeing this as the starter clutch which is the problem... Am I on the right track, or does this same symptom have something to do with the 04 upgrade parts?
