Prepare for the Trim Balance Procedure.
S 485-082-N00
(1) Do the steps that follow to install the accelerometers (See Figures
501 and 502):
WARNING: DO THE THRUST REVERSER DEACTIVATION PROCEDURE TO PREVENT
_______ THE OPERATION OF THE THRUST REVERSER. ACCIDENTAL OPERATION OF THE THRUST REVERSER CAN CAUSE INJURIES TO PERSONS AND DAMAGE TO EQUIPMENT.
(a)
Do the deactivation procedure for the thrust reverser for ground maintenance (AMM 78-31-00/201).
(b)
Open the fan cowl panels (AMM 71-11-04/201).
NOTE: It is necessary to open the left and right fan cowl
____ panels if all other cowlings are opened.
(c) Open the core cowl panels (AMM 71-11-06/201).
WARNING: OBEY THE INSTRUCTIONS IN AMM 78-31-00 TO OPEN THE THRUST
_______ REVERSERS. IF YOU DO NOT OBEY THE INSTRUCTIONS, INJURIES TO PERSONS AND DAMAGE TO EQUIPMENT.
(d)
Open the thrust reversers (AMM 78-31-00/201).
(e)
Install the MTI 2825-4045 bracket and the MTI 5500-4001 accelerometer assembly on Flange A.
(f)
Connect the Turbine Pick-up Jumper with a routing down, near the drain mast.
(g)
Install the MTI 2825-4044 bracket and the MTI 5500-4001 accelerometer assembly on Flange P at the 9 o'clock position.
NOTE: The recommended location for the "P" flange
____ accelerometer is the 9 o'clock position (Fig. 502). It is not always possible to install the accelerometer bracket at the 9 o'clock position if the engine has an oil system tubing modification. If you cannot install the "P" flange accelerometer bracket at the 9 o'clock position, install the bracket at the 1:30 o'clock position as shown in (Fig. 502). The pick-up bracket can be installed on the forward or rearward side of "P" flange.
