the other.
2.
Inspect the sheaves for wear or damage. Replace either or both of them if the damage cannot be repaired.
3.
Inspect the electric motor, repair and replace as needed.
4.
Inspect the gear reducer according to the instructions in Section 3-9-2.

Inspect the pillow block bearings for seals that leak and to determine if the bearing turns smoothly. Replace
if the seals leak or if the bearing is rough.
6.
Inspect the shaft coupling sleeve and replace if it is damaged.

3.
Install the two pillow block bearings onto the shaft and position the shaft on the conveyor frame. Install the
fasteners into the bearings. Complete the installation of the shaft coupling following the directions in Section
3-9-9.
4.
Install the sheave onto the drive shaft according to the instructions in Section 3-9-12.
5.
Connect the wiring in the junction box following the markings made during disassembly.
6.
Install the drive belts onto the sheaves. Use the torque arm and tension the belts properly. Check the
alignment using a straight edge along the face of the sheaves. The straight edge should touch at both
edges of both sheaves. If not, adjust the sheaves until aligned.
