This course is also designed to give a thorough understanding of the operation and overhaul of various Fuller® clutch models.

During the axle classroom portion, technicians will be exposed to the theory of operation, power flow, wheel differential systems, and an in-depth review of inter-axle differentials. Technicians will review a descriptive failure analysis section consisting of various axle components to increase their understanding of service life, various failure modes, and what causes them.

During the clutch classroom portion, technicians will learn clutch basics including nomenclature and clutch theory. Incorporated throughout this training will be a thorough understanding of the operation of a clutch and how to service specific clutches including the Solo®, Easy-Pedal™, and DM models. Analysis of clutch construction and design will be reviewed in detail. Technicians will also review a descriptive failure analysis section to increase their understanding of clutch life and the various failure modes of clutch components as well as which are covered under warranty.

Upon completion of the classroom presentations, the overhaul portion will continue into a hands-on tear down and reassembly of the DS-404 and the S-170/190 models using the correct tools and techniques. In addition, a hands-on tear down and reassembly of a Fuller clutch and pressure plate assembly using the proper tools and techniques will take place.
