Figure 11. Forward Transmission Impeller Accelerometer Installation
d. Mount an accelerometer (28110900) to the accelerometer bracket (29339500).
e. Install the accelerometer bracket on the stud with the accelerometer pointed to the center of rotation and the
connector pointed away from the center. See figure 11.
f.
Connect a 25-ft accelerometer cable (29105605) to the accelerometer.
CAUTION
When routing cables, ensure that cables are secured
and tied away from rotating assemblies.
g. Run the cable from the accelerometer through the most convenient cabin access to the DAU. Tie-wrap the
cable clear of all rotating components and flight controls.
h. Connect the accelerometer cable to ACC1 connector on the DAU.
i.
Mount an accelerometer (28110900) to the accelerometer bracket (29339500) for hanger bearing No. 1.
j.
Remove nut from the top bolt of the right hand No. 1 hanger bearing shock mount and orient the
accelerometer and bracket with the accelerometer pointing to the center of rotation and the connector pointed
away from the center, (use the small hole in the AVA accelerometer bracket) and tighten nut. See figure 11.
k. Repeat i and j for hanger bearings Nos. 2 and 3.
l.
Connect a 50-ft accelerometer cable to each hanger bearing accelerometer.
CAUTION
When routing cables, ensure that cables are secured
and tied away from rotating assemblies.
