Tighten the bolts (139) to 62-72 pound-inches (7.0-8.1 newton-meters).
(l)
Hold the elbow of the manifold (135) and tighten the tube nut (136) to 650-700 pound-inches (73.4-79.1 newton-meters). 1) Safety the tube nut (136) with lockwire or safety cable and
safety cable ferrule.
(m)
Connect the harness connector (140), W5P13, to the oil temperature sensor of the No.3 bearing. 1) Connect the lugs of the harness connector (140), W5P13, to
the studs on the oil temperature sensor and loosely install the nuts.
CAUTION: DO NOT TIGHTEN THE NUTS OF THE HARNESS CONNECTOR TO
_______ MORE THAN THE MAXIMUM TORQUE. TOO MUCH TORQUE ON THE STUDS OF THE OIL TEMPERATURE SENSOR CAN LOOSEN OR DAMAGE THE STUDS.
2) Tighten the nuts on the alumel studs (larger studs) to 18-22 pound-inches (2.0-2.5 newton-meters). 3) Tighten the nuts on the chromel studs (larger studs) to 15-18 pound-inches (1.7-2.0 newton-meters).
