Note
Replacing the O-rings at this point minimizes the chances of damaging the
transducer by dropping it.
6. Apply a small amount of nickel anti-seize (N.A.S.) compound (P/N 2-9-9960-134) to
the outer threads of the transducer holder (see Figure 3-2).
7. Carefully install the transducer holder assembly into the transducer mount. Make
sure the threads of the holder and mount are correctly aligned. Use a 1 ¼” socket
and screw the transducer assembly into the mount. Tighten to securely seat the
assembly in the mount. Do not over tighten (see #unique_46/
unique_46_Connect_42_fig_sym_lzl_cmb).
8. Install the keyed transformer module into the transducer holder (see #unique_46/
unique_46_Connect_42_fig_sym_lzl_cmb).
a) Apply a small amount of Molykote 111 to the transformer module O-ring.
b) Insert the keyed transformer module into the back end of the transducer
holder.
