4. Remove old belt. Note that one belt loop must surround the left hitch arm. This is the
reason for removing the cotter pin in the crossover support.
5. Install the new B158 belt (Part # 81.B158 for 60") or B180 belt, (Part #81.B180 for
72" deck) as shown in the diagram below. Begin by placing one belt loop around the
left hitch arm. Place belt into the idler pulley and then the drive pulley. Take the
belt to the right spindle pulley rotating it 1/4 turn counterclockwise.
6. Once around the pulley, follow the diagram to the other pulleys. Note: the "V" shape
of the belt should fit nicely into each pulley.
7. Tension the belt by tightening the idler adjustment rod. Spring coils should be
separated enough to slip a paper clip (approximately 1/32") between them. Reinstall
cotter pin in crossover support.
