1.
Carbon steel bolts do not require lubrication. Stainless steel bolts are factory-coated with a
lubricant to ease installation. Do not apply any additional lubricant when installing either
type of bolt.
2.
Finger-tighten the bolts.
3.
Torque the bolts to the initial torque value using a crossing pattern. See
Table 2-3
for initial
torque value.
4.
Torque the bolts to the final torque value using the same crossing pattern. See
Table 2-3
for
final torque value.
5.
Verify that the flange bolts protrude through the sensor module before applying pressure.
