A couple of suggertions. Take some pics of the process so everyone can see and while your in there why not install Harleys SE Camplate and HV oil pump?.
I recently opened mine up and installed Feulings Camplate and HV oil pump along with Zippers duel piston camchain tensioners. I like it however, there is a less expensive way to go and that is use Harleys part# 25282-11 for $429.00. Hey, your in there, right?
