(3) Lubricate the thermocouple probe bolts (80) with graphite grease (Material No. CP2101).

 (4) Install the four bolts (80) in the thermocouple probe flange. TORQUE the bolts (80) to between 55 and 70 lbf.in (0.62 and 0.79 m.daN). Wirelock the bolts (80) with lockwire 0.8 mm dia (Material No. CP8001) or lockwire 0.8 mm dia (Material No. CP8002).

 (5) Lubricate the electrical cable connector unit bolts (20) with graphite grease (Material No. CP2101).

 (6) Attach the electrical cable connector unit to the forward bracket with bolts (20) and nuts (10). TORQUE the nuts (10) to between 55 and 70 lbf.in (0.62 and 0.79 m.daN).

 (7) Lubricate the mid-conduit bracket bolt (50) with graphite grease (Material No. CP2101).

 (8) Install the bolt (50), washer (60) and nut (70) at the mid-conduit bracket. TORQUE the nut (70) to between 55 and 70 lbf.in (0.62 and

 0.79 m.daN).

 (9) Remove the blanking caps from the electrical connectors.

 (10) Make sure that the electrical connectors are clean and in the correct condition.

 (11) Connect the 2 electrical cable connectors (30, 40). Tighten the connectors by hand. If necessary, use soft-jawed pliers to fully seat the connectors.

R **ON A/C 001-049, 052-099, 101-149, 151-199, 201-299, 301-399, 401-499,
 The engine vibration measurement channel comprises :
 - two transducers (piezoelectric accelerometers)

 - an Engine Vibration Monitoring Unit

 - two vibration indications N1 and N2.
 They appear on the lower display unit of the ECAM, on the engine and cruise
 page.
 The engine vibration system provides the following functions :

 - vibration indication due to rotor unbalance via N1 and N2 slaved tracking filters

 - excess vibration (above advisory levels)

 - fan trim balancing

 - shaft speed (N1 and N2)

 - storage of balancing data

 - BITE and MCDU communication

 - accelerometer selection

 - frequency analysis when the printer is available (option).
