This completes the assembly of rotating unit.
6.4.4 Now lift the above rotating unit and fit it properly in the lower half casing so that
pins (610.1, 610.2) take their proper seating.
6.4.5 Fit the two bearing caps by means of bolts. Rotate the whole unit and see that there
is no friction between rotating and stationery parts.
6.4.6 Cut the paper packing to match the profile at the upper and lower half casing. Put
the paper packing (dipped in linseed oil) on the lower half casing. Keep the upper
half casing gently and neatly without disturbing the impellers or packing etc. Insert

6.4.7 Now insert the bolts and nuts for upper half and lower half casing and tighten them.
While tightening the nuts, take care to tighten the diagonally opposite bolts. Rotate
the impeller by rotating driving end of shaft and see that there is no friction between
the rotating unit and stationery parts.
