NOTE
Regardless of the nature of the contamination, proper and complete flushing
of the steering system is critical to avoid future down time and repairs.
NOTE
Do not use a SeaStar power purge unit to flush the system if there are
signs of contamination. Doing so may damage the power purge unit and
re-introduce contaminants into the system.
7.
Replace steering cylinders
• If cylinder replacement is required then replace with the same
cylinder or updated -3 model. Consult with your owner’s and
installation instruction manual for part numbers.
8.
Cure fluid leak
• If the cylinder shafts are clean and free of any pitting, corrosion or
marks, and, the cylinder end glands are leaking. Replace seals with
appropriate seal kit.
• If you see fluid leaks coming from the elbow hose fittings (see figure
8-2, item 5). Remove elbow fitting completely, clean off threads of
elbow fitting, then apply a “liquid” Teflon based pipe sealant to the
threads going into the cylinder body only. Torque fitting to the
appropriate value.
•
If you see fluid leaks coming from the bleeder fittings. Tighten bleeder
fitting. If leak persists, replace bleeder fitting with part # HF5548.
9.
Flush steering system
•
DO NOT re-use any of the fluid used to flush the system out. Dexron III
ATF can be used for flushing, but should not be used for the final
bleeding procedures. Dispose of fluid in a manner consistent with
your local regulations.
• Flushing can be achieved via running several bottles of fluid through
the system, pumping fluid and contamination out of the cylinder
hoses (cylinder hoses to be removed). Once several bottles of fluid
`have been run through the system, in both the starboard and port
directions, it is highly suggested that the steering lines are blown out
using air pressure.
10.
Ground Strap
• Installation of a ground strap on every cylinder in the system will
assist with the prevention of stray current corrosion. Stray current
corrosion is the leading contributor to pitting of the steering cylinder
shafts. Part # HA5477 contains one ground strap for non -3 cylinders.
For -3 cylinders contact Dometic technical services.
