PEDESTAL STEERING
The optional pedestal steering system on your Cape Dory has been
carefully designed, installed, and aligned here at the factory to give
you excellent service with minimal maintenance.
The system is composed of a pedestal steerer with a 22 inch stainless
steel wheel. The chain and cable assembly travels through a pair of
idler pulleys thru bolted to the underside of the deck and connect to an
8" radial drive wheel. This system provides 1.6 turns hard over to hard
over.
The rudder itself is guided by an upper shaft and lower gudgeon bearing
with a stainless collar below the upper bearing to prevent the rudder
from jumping.
A 1-1/8" stuffing box guides the shaft through the hull. This stuffing
box requires 1/8" flax packing for replacement, 10-1/2" long. Replace
the packing when leaks cannot be controlled or once a year.
The radial drive stop limits the swing of the rudder to about 35 degrees
both to port and starboard. This is especially useful when motoring in
reverse, as the rudder would tend to swing completely to one side with
great force resulting in possible damage to either the hull or steering
system.
During installation, we have replaced many of the vendor supplied nuts
with self locking nuts as we have found they will otherwise loosen
during road transit, engine vibration, and general use.
It is imperative that the owner take the initiative to inspect the
steering system for proper wire tension, wire alignment, and fastener
tension during the sailing season. Periodic maintenance is also
required on all moving parts. In particular, the lubrication of the
bronze sheaves is critical to the smooth operation of the steering unit.
The keyway that is cut into the rudder shaft is purposely cut a little
long to accept an attachment for a number of automatic pilot systems.
This saves a very costly alteration from having to be performed in the
field were another keyway to be cut and eliminates the need to bolt
something through the shaft which would tend to weaken it.
The head of the rudder shaft above the pillow block bearing has been
keyed to accept an emergency tiller. Access for this is gained by
removing the bronze deck plate in the cockpit sole.
Should anything ever happen to your primary steering system, the key for
the deck access plate and the emergency tiller should be readily
accessible and not buried in the bottom of a locker.
Please review carefully the enclosed maintenance hints supplied by the
vendor. A thorough understanding of how your steering system works is
the only way you can be assured of its proper performance year after
year.
