Remove nut from the top bolt of the right hand No. 4 hanger bearing shock mount and orient the accelerometerand bracket with the accelerometer pointing to the center of rotation and the connector pointed away from thecenter, (use the small hole in the AVA accelerometer bracket) and tighten nut. See figure 10.m. Repeat steps k and l for hanger bearings no. 5, 6 and 7.n. Connect a 50-ft accelerometer cable to each hanger bearing accelerometer.CAUTIONWhen routing cables, ensure that cables are securedand tied away from rotating assemblies.o.
