Installing the Adapter Plate
1. Mounting the Plate:
Weld or Bolt the adapter plate to the leveling weldment. If the adapter
plate is bolted to the weldment, coat the adapter plate surface that will
contact the weldment with approximately a 3 mm
thick coating of
caulking. Apply caulking to the four bolts (not supplied) and install the
adapter plate to the weldment. Remove excess caulking.
2. Mounting the
Uncoil
the
transducer
cable and feed it up through the adapter plate, the
weldment, and stuffing tube into the inside of the hull. Never pull of carry
the transducer
by
its
cable---this
may
damage internal connections. Do not
hold the transducer in place by applying tension to the transducer cable.
Apply a 3 mm
thick layer of caulking to that surface of the transducer
which will contact the adapter plate. Slide the rubber washers (to reduce
stress concentration in the resin
housing
the bold hole area)
stainless
steel washer supplied with the transducer onto the transducer mounting
bolts and then apply caulking to the threads of the two
x 1
long
stainless steel mounting bolts. See the figure above for the correct orien-
tation of the washers.
Holding the transducer against the adapter plate, thread the mounting
bolts into the adapter plate. Tighten the bolts with a torque wrench to
(7 newton-meters). Remove excess caulking.
