My manual specifies useing a MD998051-01, is this tool neccesary or can I just get a certain sized hex head socket? If so what size is it?

Obviously the motor is out, and I am now just tearing it down to get it ready to take to the machine shop.. I just need to know what I might need to pulle the heads off..

Thanks,
John
