Duration: Three Days

This course is designed to give a basic understanding of how to determine the root cause of various component failures of Roadranger products. Technicians will learn to determine what failed, how it failed, and possible causes. The objective is to increase the technicians understanding of gear life and various failure modes of the Roadranger components while understanding which failure modes are covered under warranty. This class will also provide a basic understanding of the operation and overhaul of Spicer Heavy-Duty Drive Axles. This includes all DS series and S series heavy-duty tandem axles.

This course will be delivered in two possible ways. In most cases, the failure analysis material will be covered at the end of a particular product training class (transmission, axle, clutch, driveline, or brake). The class can also be delivered as a standalone failure analysis program covering all Roadranger products such as: transmission, axle, clutch, driveline, and brake.

During the 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 and various failure modes of the components. Upon completion of the classroom presentation, 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.
