Not sure if you have a manual for the old girl, so I will post the instructions and diagram of the cutter belt run, also according to my manual the belt No: is GT 18005.

Edit: If the cutter belt has been re-tensioned before, you can loosen it by reversing the tensioning instructions in the second picture.
