Replacing the Blade Pulley
The Blade Pulley is designed to protect the drive system of the machine. If the
machine is overloaded the hub and pulley may fail. Please follow these
instructions to replace
Tools and Supplies Needed:
Gloves
1/2" Wrench
1/2" Drive Ratchet
15/16" Wrench
Torque Wrench with 15/16″ Socket
1. Loosen the four Bolts using a 1/2″ Wrench and lift up to remove the Belt
Cover (Figure 45).
2. Insert the 1/2″ Ratchet into the square in the Idler Arm. Turn the Ratchet
clockwise to move the Pulley away from the Belt.
Note: If you use your hand to remove the Belt, wear Gloves. A Rope looped around
the Belt also works well to pull it off the Pulley.
3. As you hold the Idler out of the way with the Ratchet using your right hand,
rotate and lift the Belt up and out of the Pulley groove using your left hand
(Figure 46).
4. Block the blade with a block of wood (Figure 42) as you remove the Pulley
Locknut using a 15/16" Wrench (Figure 47).
5. Remove the damaged Pulley and replace with a new Pulley.
Note: Ensure that the square Key is in the Shaft (Figure 48) and that the Hub of
the new Pulley is facing up.
6. Secure the Pulley with the Locknut and torque to 50lb-fts (68N-m).
7. Start the Belt into the groove of the Blade Pulley and turn the Pulley as you
guide the Belt around and into the Pulley groove (Figure 46).
8. Install the Belt Guard onto the Deck and tighten the four Bolts to secure it
(Figure 45).
