I have a little play in the steering . Unhook battery terminal +. Remove tank and tank support .
On this one the key way is a little worn on the pulley . Replaced the key cleaned up and re assembled . The machine has over 10,000 hrs . Not worth buying a new pulley .Seems good now . If it's still a problem I might have to use some JB weld on it next time to tighten up the gap .A better fix would be to drill a hole 180 degree from the key way and tap threads for a set screw .
