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 3-4).
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 Figure 3-5).
8. If replacing T-21 or T-22 transducers, install the keyed transformer module into the
transducer holder (see Figure 3-5).
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.

9. For T-21 and T-22 transducers, place the retainer over the transformer assembly.
Ensure the retainer threads are aligned correctly and hand-tighten. Use a 1 ⅛”
