how in the world does this go back on.. I removed it to do my belts , unfortunately I did not look to see how it is attached when I took it off . I thought it was just a bar holding something obvious .. now I can't not get it back on. I think it fits in a groove in the upper pulley but when I tighten it that end goes up out of the groove ..do I have it in the wrong place , what am I missing ..I've fooled with this longer than it took me do do both belts..I know it locks the clutch in place so the wires don't get ripped out ...anyone have a picture or can tell me what I'm doing wrong...thanks for any help....Husqvarna LOYTH20F42T ABOUT 10 YEARS OLD
