You are supposed to move the crank gear 3 teeth cc, this takes the slack out of the front of the belt (longest straight part). Then tighten the tensioner, you shouldn't have to move the tensioner, just tighten it. I just did mine last night, and have yet to put the other 3 belts back on. Now your making me nervous. I hope it's right, cause I do not feel like taking everything apart again.
