found a ford finish mower for my g152 tx1300, cleaned and greased it up and set it up for my tractor and in the process of testing it out i started smelling coolant so i pulled out of the field and shut it down right away raised the cover and my belt was only half of the original width. so i cut the belt off and i spun the alternator and i think my bearings are shot because it was really hard to turn. so can it be rebuilt or would i be better of replacing it. either way it goes im holding on to my tractor, its as handy as a pocket on a shirt. any tips, thanks in advance
