This document provides guidance for reconnecting the control yoke on an Embraer 170 aircraft. It notes that the specified task procedure should be followed. The area around the disconnect device is clear and accessible without removing parts. Using a multimeter with long leads can help detect when the device is reconnected by listening for a sound. When reconnecting, the wrench jaws should move outward from each other and the wrench should be turned for 2-3 turns after hearing the sound to ensure a strong reconnection.
2. The Task
Task 27-11-12-840-801-A gives all steps and
procedure to carry out the Control Yoke Disconnect
Device Reconnection.
In this presentation we will focus on some points which
might be help, where we carried out this task few days
ago.
But you have to obey the task.

3. The Practices Note
You do not need to remove any parts to reach the
Disconnect Device. The Area is clear to set the tools.
It will be good to use a Multimeter with long terminal
leads, to be far enough to hear the sound, as result of
Close Circuit between pins A & B.
You have to know that the Reconnect Wrench jaws
movement should be out of each other.
When you hear the sound of the Multimeter, do not
stop. Wait for seconds, and turn the Reconnect
Wrench for more 2 or 3 turns. You will feel a strong
reaction, then stop.
