Systems

Shows how the oil systems work in V- and radial-type engines, and in wet- and dry-pump systems. Traces oil flow from tank through external and internal system, pointing out oil tanks, screen and self-cleaner type strainers, pressure-relief valves, pressure gages, oil-temperature regulators, oil lines, oil coolers, viscosity valves, and spring-loaded type valves. Closes by showing periodic oil-system check-up and how to trace simple oil-line failures.
