Checking oil level, servo pump
The oil recovery tank is a see-through reservoir, check
oil level without opening the reservoir. Oil should be
right below the neck of the recovery tank.
If oil needs to be added, first disconnect quick connect
coupling, before opening the cap.
Hydraulic hoses. Checking
Carefully check the steering system's hydraulic hoses
for wear and cracks. Check external hoses especially
carefully, as these have been exposed to water fatigue.
Hoses must be replaced if at all damaged.
WARNING! A leaking hydraulic hose can nega-
tively affect steering, and at worst steering can be
lost altogether. Cleanliness is extremely impor-
tant, no dirt must get into the hydraulic system.
Before removing, clean and check carefully how
hoses are routed and connected. Faulty routing
or dirt in the hydraulic system can negatively
affect steering, and at worst steering can be
lost altogether. Please contact your nearest au-
thorized Volvo Penta workshop for assistance.
Parallel strut. Checking
The parallel strut (twin and triple installation) is a vital
safety component. Inspect it carefully if the drive kick-
up function has been triggered by the boat going
aground or hitting an object in the water.
WARNING! If the parallel strut shows signs of
damage, run at reduced speed to harbor. The par-
allel strut is a vital safety component, damage
may affect steering characteristics. In the worst
case steering could be lost altogether. Never align
or weld a damaged parallel strut. Please contact
your nearest authorized Volvo Penta workshop for
assistance.
