The clutch removal tool your probably thinking of and see in a lot of for sale ads is for the PRIMARY Clutch..it has threads..suggestion..try soaking it with penetrating oil for a day or 2 and then use a heat gun (hair dryer type NOT a torch) I have had sucess with this method..key is to spray oil anywhere you can see the shaft in the hole (the one without threads) AND LET IT SOAK...Good luck and remember that $300.00 figure everytime you want to hurry it up
