Hi I have a RCK60P-400Z (also known as Z421). It stopped moving forward or reverse. When I looked, the high tension spring was on the ground and as i was looking further i saw a shrouded belt hanging down. I have looked on all the parts diagrams and can not seem to locate a diagram of that belt. Could anyone direct me to that? I don't yet know what the part (belt) is called. Thanks for any advice I have got to try and fix myself as the shop is 120$ PER HOUR. RICK
