4.0 General Preparations
Read and understand all instructions before installing and tensioning studs
4.1 Machine Preparation
The flange to be tensioned must be fully closed prior to positioning of studs in the flanges.
Turning the shafts of the turbine and the generator are not required, but may be useful. Also, it
will be advantageous to remove as many obstructions as possible from the flange area, such as
speed probes, shipping plates, and conduit.
4.2 Hardware – Balance
Hardware is supplied as weight balanced sets
Studs and Nuts are interchangeable within sets
Do not intermix sets
Save weight certification supplied with each set for the purchase of spares
4.3 Tensioner – Care and Handling
When not in use, the tensioner shall be maintained in a clean environment and all caps
and plugs for hydraulic openings and fittings must be in place.
Use ISO 32 grade oil.
When in use, the tensioner shall be protected from sand and grit.
Long term storage – coat tensioner with oil, return to original container, seal container
and protect from moisture.
