AGM 251: Drivetrains II

Credits 5 Lecture Hours 33 Lab Hours 44
A continuation of Drivetrains I, this course covers the safe servicing practices of hydraulically lubed axles, semi and full powershift transmissions, service and park brakes, and differential locks. Other topics include hydraulic clutches, lube circuits, and hydraulic brakes. Students will practice operating, calibrating, and configuring both electronically and non-electronically controlled systems.
