Parts needed for this procedure:

Pulley assembly	1
Pulley-plate mount—for machines with an aluminum spindle only	1
Flange nut (3/8 inch)—for machines with an aluminum spindle only	3

Remove the top nut, washer, and sheave from the spindle (Figure 5).

Note: Note the orientation of the sheave when you remove it from the spindle to ensure that you install it properly later in the process.

Torque the top nut to 176 to 217 N∙m (130 to 160 ft-lb).

Note: Ensure that the sheave spins freely.
Align the new pulley assembly so that the openings fit over the nuts (Figure 9).

After the new pulley assembly is in position, tighten the nuts to secure new pulley assembly.

Torque the 3 nuts to 28 to 34 N∙m (21 to 25 ft-lb).
Install the deck belt.

Loosen, but do not remove, the tapping bolts on the existing mower-deck pulley (Figure 11).

Note: There should be a 5 mm (3/16 inch) clearance between the bolt head and pulley.
Align the new pulley assembly so that the openings fit over the pulley bolt heads (Figure 11).
Turn the pulley to lock it into position (Figure 11).

Note: If the pulley does not turn, loosen the bolts more to raise the bolt heads and allow the pulley to lock into position.
After the new pulley assembly is in position, tighten the existing bolts to secure new pulley assembly.

Note: Torque the bolts to 28 to 34 N∙m (21 to 25 ft-lb).

Install the deck belt.

Note: Do not perform this procedure if a pivot is installed.

Clean the area around the right, rear anti-scalp roller.
Remove the anti-scalp roller from the bracket by loosening and removing the flange nut (3/8 inch) and axle bolt (3/8 x 4-1/2 inches) as shown in Figure 12.

Save all hardware for later use.
Remove the 3 carriage bolts (3/8 x 3/4 inch) and 3 flange nuts (3/8 inch) securing the bracket to the mower (Figure 12).

Save all hardware for later use.

For a 60-inch Bagger

Parts needed for this procedure:

Note: Do not perform this procedure if a pivot is installed.

Install the metal template with the number 60 in it to the mower deck with the previously removed carriage bolts and nuts using the existing holes in the mower deck (Figure 13).

Ensure that the carriage bolts and nuts are tight and the template is tight against the mower deck.
Center-punch the new mower deck hole locations using the 3 holes in the template (Figure 13).
Remove the metal template and drill 3 pilot holes (1/8-inch diameter) with a sharp drill bit (Figure 13).
Drill 3 holes (13/32-inch diameter) into the pilot holes with a sharp drill bit (Figure 13).
