I put a new belt on the mower and the adjustment bolt is 2 inches off from the previous setting with the old belt. The 2 in. difference is after I adjusted to the recomended 5 9/16th in spring length on the tension spring. Belt felt too tight after I tried adjusting up to the previous mark I had placed on the adjusting bolt prior to removal. So then I got out the manual and adjusted to their setting. Belt is OEM , same part #. Old belt was 9-10 yrs old. Havent put deck on and warmed up the belt yet at speed. I heard that a good belt shouldnt loosen up with use after fresh install. Anyone been through this? Tractor and deck are 1999 TC33D
