5 Installation of Seal (Method 1)

5.1 Remove the seal assemblies from the box. Inspect for any obvious signs of

mishandling or damage.

5.2 Set aside the sleeve gaskets 19 , ange gaskets 18 , and lock pins 5

for installation later.

5.3 Spin the spanner nuts 9 until there is a .375 inch gap between the

retaining rings 54 and the ange shoulders. This simulates the installation

of the .375 inch wide ange gaskets 18 .

5.4 Lower the seal assemblies into the proper grooves in the turbine casing per

the assembly drawing. The setting devices 103 should be oriented at the

12 O'clock position. Lower the bearing caps into place to insure proper t

of the assemblies. The spanner nuts should not interfere with the bearing

caps.

5.5 The seals should seat fully in the turbine case. If they do not, the turbine will

not seal at the split line. Measure the turbine bore diameters and the seal

OD diameters to ensure adequate clearance. Compare with the information

on the assembly drawing.

5.6 Mark the location of the lock pins 5 . These lock pins will prevent the seal

anges from rotating in the turbine casing. A small slot must be milled or

ground into the casing for each pin so that the pins do not interfere with the

lowering of the top half of the casing. The slots should not be any larger

than necessary to contain the pins and should not break into the adjacent

gasket sealing areas.
