Hydraulic Steering Pump
Located under the aft center cockpit storage com-
partment is the steering system hydraulic pump
system. Each pump controls the port or starboard
steering cylinder. The Optimus steering system
uses the HA5482 EPS power steering fl uidl. Do
not use any substitutions. It is a good idea to have
extra fl uid, funnel and cloth on board for emer-
gency fi lling of the system. Also, note that there is a service valve lo-
cated on each pump. It allows for manual realignment of the engines
during service or a system fault. Use the decal information as needed
for manual realignment situations. Engine(s) must not be running
while performing these realignment procedures.
