Duration: 3 days

This class is designed to give a basic understanding of the operation and overhaul of Spicer Heavy-Duty Non- Drive Axles and Foundation Brakes. This includes the most popular non-drive, heavy-duty steer axles, current LMS systems, drum and air-disc foundation brakes. 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.

During the classroom portion, technicians will be exposed to the theory of operation, maintenance, troubleshooting and repair. Technicians will review various failure modes of the components and what causes them. Finally, technicians will be exposed to the theory of operation, power flow, wheel differential systems and an in-depth review of inter-axle differentials.

Upon completion of the classroom presentation, the overhaul portion will continue into a hands-on tear down and reassembly of the foundation brake, steer axle, and LMS hub systems. There will also be a hands-on tear down and reassembly of the DS-404 and the S-170/190 models using the correct tools and techniques.
