HONDA 4518 W/46 DECK PTO BELT INFO

I bought a 105" kevlar wrapped belt following web advice. Install was nearly impossible. I disconnected the tensioner and removed the spring loaded idler pulley on RH side. With force I loaded the belt and replaced the pulley to close it up. However now I cannot reconnect the tensioner, the screw is about 1 inch too short. I haven't determined where to pull or push to make it move enough to reconnect. Pulling on it doesn't work. Question: Was the 105" kevlar 5/8 belt correct? It does work...
