7. Engage PTO lever and check the clearance
between the bell crank and the transmission
output shaft (Figure 171). Space should be 1/16” -
1/8” (2 - 3mm).
8. Remove hairpin cotter and clevis pin from bell
crank. Rotate clevis clockwise on rod to increase
or counterclockwise to decrease clearance
(Figure 171).

contact the front stop on the mower deck (Figure
170), readjust the clevis to bring the bell crank
closer to the transmission output shaft (Figure
