Table34: Tightening torque (61009)
1) Pre-tightening torque of the screws
1. Fit two guide studs(90317) in the upper area on the gas outlet casing(61001).
2. Loop around the gas inlet casing(51001) with the lifting gear and secure it to the crane.
3. Push gas inlet casing over the guide studs up to the gas outlet casing.
4. Screw in two opposite screws (61009) with high-temperature grease.
5. Remove the guide studs (90317) and fit the remaining screws (61009) with high-temper-
ature grease.
6. Fit the screws (61009) by tightening them crosswise, first to the pre-tightening torque,
then to the tightening torque.
