Ensure that the foundation that will support the installation is level within 10 mm (0.3937 inch). Intermediate plates between each isolator and the foundation can provide a level foundation. Refer to the engineering print for the installation that is specific to the engine application.
Remove nut (2) and washer (3). Place adjusting nut (4) in the neutral position by turning the nut until the top of the nut is above the top casting (7) by 20 mm (0.7874 inch).
Attach each mount to the mounting holes on the rail. Install washer (3) and nut (2) onto the internal limiter (5). Hand tighten nut (2). Take care to bring the internal limiter (5) in the upper position by turning the internal limiter counterclockwise with a spanner on the top hexagon. Ensure that the identification plate is visible.
Turn the four lower nuts (10) clockwise about two turns. Turning the nuts allows the top casting (7) to move when the mounts are loaded. After installation of all mounts, gently lower the equipment until the mounts take the load.
Check that all the bolts (6) are free to rotate manually. If bolts (6) are not free to rotate manually, refer to Steps 5.a and 5.b.
Turn the internal limiter (5) clockwise by one and half turns.
Turn four bolts (6) until the four bolts are free to rotate manually.
