2. Loosen, but do not remove, the tapping bolts
on the existing mower deck pulley (Figure 3).
There should be a 3/16 inch (5 mm) clearance
between the bolt head and pulley.
3. Align the new pulley assembly so that the
openings fit over the pulley bolt heads (Figure
3).
4. Turn the pulley to lock it into position (Figure
3).
Note: If the pulley does not turn, loosen
the bolts to raise the bolt heads and allow the
pulley to lock into position.
5. After the new pulley assembly is in position,
tighten the existing bolts to secure new pulley
assembly.
Note: Torque the bolts to 23 ft-lb ± 2 ft-lb
(31 N⋅m ± 3 N⋅m).
