5) After 48 hours, level and load distribution is
checked by measuring the height of the ele-
ments. The difference between the mountings
should be as small as possible and should not
exceed ± 2 mm from average.
6) The mounting(s) with the largest deviation (from
the average) should be adjusted first with steel
shims. Hereby it should be noted that with the
steel shims the mounting deflection can only
be increased. Therefore it can be necessary to
fit, not only one, but all mountings with steel
shims to release one mounting.
Method of fixing the generating set to the
base plates
7) After the final adjustment, fix the Generating
Set to the base plates by welding the filling
pieces to the base plates according to the
drawing from MAN Diesel & Turbo,
see also
page 4.
This method of fixing the Generating Sets to the
base plates is suitable for earthquake conditions up
to 7 on the Richter scale (If higher conditions is
required, please contact MAN Diesel & Turbo).
Instructions for maintenance
Generally speaking the mountings will not require
maintenance or reconditioning in service unless
mis-used or accidently damaged.
Oil contamination is the most likely cause of dam-
age and therefore the rubber elements are treated
with an oil resistant coating. Certainly elements
showing signs of severe swelling or evidence of
rubber to metal separation should be replaced.
