Replacing the I/P Converter

1. Refer to figure 7-2. Inspect the condition of the
O-ring (key 39) and screen (key 231) in the module
base (key 2). Replace them, if necessary. Apply
silicone lubricant to the O-rings.
2. Ensure the two boots (key 210) shown in figure 7-3
are properly installed on the electrical leads.
3. Install the I/P converter (key 41) straight into the
module base (key 2), taking care that the two electrical
leads feed into the guides in the module base. These
guides route the leads to the printed wiring board
assembly submodule.
4. Install the shroud (key 169) over the I/P converter
(key 41).
5. Install the four socket-head screws (key 23) and
evenly tighten them in a crisscross pattern to a final
torque of 1.6 NSm (14 lbfSin).
6. After replacing the I/P converter, calibrate travel or
perform touch-up calibration to maintain accuracy
specifications.

Printed Wiring Board (PWB) Assembly

Refer to figure 8-2 for key number locations. The PWB
assembly (key 50) is located on the back of the
