Table36: Tightening torque (51087)
1) Pre-tightening torque of the screws
1. Coat threaded stud (51086) with high-temperature grease, screw in up to the stop in the
gas outlet casing (61001) and tighten hand-tight.
2. Loop around the gas inlet casing(51001) with the lifting gear and secure it to the crane.
3. Dismantle and remove support(90451) from the gas inlet casing.
4. Push gas inlet casing over the threaded studs up to the gas outlet casing.
5. Coat two nuts (51087) with high-temperature grease and fix gas inlet casing in two op-
posite positions.
6. Coat remaining nuts with high-temperature grease, fit and then tighten crosswise, ini-
tially to the pre-tightening torque and then to the tightening torque.
7. Remove the lifting gear.
8. Connect the flange of the gas inlet casing and the bellows.
9. Fit the insulation segments(51215).
