A. Installation of the T5 Sensor:
(a) Clean the component interfaces and the adjacent area.
(b) Do an inspection of the component interfaces and the adjacent area.
(c) Remove the blanking cap from the T5 sensor (10) connector.
(d) Apply a thin layer of graphite grease (Material No.CP2101) to the threads of the 4 screws (120).
(e) Engage the T5 sensor connector through bracket (170). Attach the bracket to the connector with screws (120) and half-plates (160).
(f) TORQUE the screws (120) to between 10.5 and 9.5 lbf.in (0.12 and 0.11 m.daN )
. Safety the screws in pairs with a CP8004 lockwire 0.6 mm (0.0236 in.) dia or CP8005 lockwire 0.6 mm (0.0236 in.) dia .
(2) Installation of the T5 Sensor Assembly

(b) Engage the T5 sensor probe (10) in the recess of turbine frame boss. Install the bolts (110) and nuts (100). Tighten the nuts by hand.
(c) Lubricate the threads of the bolts (20, 60) with graphite grease (Material No.CP2101) .
(d) Attach the T5 sensor (10) to the bracket (40) at flange T with the clamp (30), the bolt (20) and the nut (50). Tighten the nut by hand.
(e) Attach the T5 sensor (10) to the bracket (80) at flange S with the clamp (70), the bolt (60) and the nut (90). Tighten the nut by hand.
(f) Lubricate the threads of bolts (150) with graphite grease (Material No.CP2101)
(g) Attach the bracket (170) and the T5 sensor (10) assembly to the bracket (140), at flange R, with the bolts (150) and the nuts (130). Tighten the nuts by hand.
(h) Make sure the T5 sensor rigid lead is installed stress-free on the engine and, from rear to front:
(j) TORQUE the coupling nut of CJ13 harness connector to between 160 and 150 lbf.in (1.81 and 1.70 m.daN )
. Safety the coupling nut with a CP8004 lockwire 0.6 mm (0.0236 in.) dia or CP8005 lockwire 0.6 mm (0.0236 in.) dia .
