High temperature bolt lubricant "Rivolta G.W.F“ *
* or comparable product
Procedure:
1. Remove exhaust pipe sheathing.
2. Check tightness of all bolt connections.
NOTE
In order to prevent longitudinal strain of the expansion joints, they should not be sub-
jected to bending and/or radial forces during disassembly and assembly.
However, for the expansion joint ahead of the turbine, a slight preload in axial direc-
tion (strain) is required during installation.
Coat all bolts with high temperature bolt lubricant "Rivolta G.W.F." before installation
in order to protect them from seizure.
DANGER
Caution, hot engine components can cause burns!
Always check temperatures before beginning work on exhaust pipes! Let exhaust
piping cool sufficiently!
