I posted about the perfect cluth tool that I have had great luck with and it is cheap!Look in your local hardware or welding shop for an adjustable spanner wrench.This tool has a box end wrench on one end,(for opening and closing the tanks?)and an adjustable spanner on the other with a good solid set of pins on the other.I spent about $4.00 each and keep 2 around at all times.I have yet to come across a clutch i can't get off with this tool!!!!!!!
