My carbon ring is hurt and im going in... I have the shop manual for my machine and i know that there are three tools needed for this job. Are these tools really nesessary or can i save myself some money. The one tool that i question is the PTO support tool and how important is it as far this job is concerned. Everything i'm reading online is on earlier machines and not able to gather good information on the later skiis. The shop manual is great to a point but im really interested on what evryone has encountered . Thanks
