As an instructor, have you struggled to demonstrate how a differential system works to your students? The EC-431 is a working system of actual components so students can visualize the mechanical operation of an open differential and make your life easier as an instructor. The EC-431 provides an easy method of demonstrating differential operation and also the common adjustments made during common service procedures.



  • Provides full visibility and accessibility to all components without the limitations of working under a vehicle
  • Takes the mystery out of differential operation
  • Sits on a bench or tabletop to allow more student access and visibility of component operation
  • Demonstrates how movement of the differential components affect adjustment
  • Cutaway assembly to easily show components
  • Uses repurposed “real” automotive components
  • Engages multiple students for operation of trainer
  • Provides ability to:
    - Make and check common adjustments
    - Visualize differential gear movement



  • Provides component identification exercises for students
  • Allows demonstration of proper design and location of common differential parts and components
  • Instructors can easily demonstrate the operation of a typical differential
  • The EC-431 provides hands on learning by moving the pinion gear in and out of mesh with the ring gear and allows adjustment of the ring gear position by changing the backlash using hand adjustments

The ConsuLab EC-431 cutaway trainer is an application that can be chosen to demonstrate the operation of an adjustable open rear differential.



I got the half car out of the crate and working yesterday and today I had my Level 3 Electronic Climate Control diagnostics lab using it. This teaching aid is great! The workmanship and design is excellent and it is just perfect for the Level 3 curriculum, including the upcoming changes. We were fortunate that the IPro scan tool we received from the Uniselect donation communicates quite well with the Audi CAN bus system. The Audi also has the electronically controlled, clutchless compressor which is covered in our theory classes so it's a good reinforcement to be able to see it in action, manipulate it and communicate with it. I am very pleased with the quality and applicability of our ConsuLab products (including the engine/AC bench we got recently). They allow me to teach up to 8 students in great detail, whereas only one or two at a time can be involved in a full car. I am looking forward to the imminent arrival of our AC board. Thanks for your excellent insight of design and quality of manufacturing.
