Thanks for the link to that, but like I said, there is no hydraulic tensioner on this one, it was originally a spring tensioner and will be again. In all actuality, the tensioner could be done away with as it's only real purpose is to hold tension on the belt as you make your 2 full rotations. After that, the idler bolt is torqued to 27fps. Although it sure would help if for some reason one forgot to torque that bolt, at least until the bolt fell out.
