In each
system the descriptions will concentrate on the hydraulic system found on units
that have (or originally had) the Mk-I EHC systems. Discussion will
include the reservoir construction / major components, the hydraulic pumping
system, fluid actuating supply, the fluid to cooler drain, the transfer / fluid
earth filtering unit, instrumentation and operating procedures. For each
typical alarm, discussions will include the alarm implications, probable
causes, and actions to be taken.
