Duration: 3 Days

This class is designed to give a basic understanding of the operation and overhaul of Spicer® heavy-duty drive axles, including all DS Series and S Series heavy-duty tandem axles. This course is designed to give a basic understanding of vehicle systems and how they interact with each other to cause common vibration complaints. These systems include the complete drivetrain and the vehicle. 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 the inter-axle differentials. Technicians will review a descriptive failure analysis section consisting of various axle components to increase their understanding of service life and various failure modes of the components and what causes them.

During the driveline classroom portion, technicians will be exposed to the theory of operation, maintenance, and troubleshooting procedures for Spicer® drivelines and u-joints. Technicians will be instructed on the calculation of joint working angles using the Roadranger Driveline Angle Analysis (DAA) program. Technicians will also review a descriptive failure analysis section to increase their understanding of the various failure modes of a driveline, as well as which modes are covered under warranty.

During the clutch classroom portion, technicians will be exposed to clutch basics including nomenclature and clutch theory. Incorporated throughout this training is a thorough explanation of the operation of a clutch and how to service specific clutches including the Solo®, Easy-Pedal™, and DM models.

Upon completion of the classroom presentations, the overhaul portion will continue into a hands-on tear down and reassembly of the DS-404 and S-170/190 models using the correct tools and techniques. In addition, a hands-on tear down and reassembly of a driveline and u-joint using the correct tools and techniques will also take place.
