Background

This procedure describes how to remove and replace the unloading platform motor.

• The unloading platform motor is a DC motor and operates both the rollers and the platform belts.
• The motor has an internal gear with a ratio of 65:1.
• The motor is connected to the lower roller sprocket and to the flat belt rear axle, via a timing belt.
  
  

The motor can be removed without taking out the conveyor assembly.
