The entablature is the name given to the cylinder block which incorporates
the scavenge air space and the cooling water spaces. It forms the housing
to take the cylinder liner and is made of cast iron.
|
The castings are
either for individual cylinders which after machining on the mating
surfaces are bolted together to form the cylinder beam, or they may be
cast in multi - cylinder units, which are then bolted together. The
underside of the cylinder beam is machined and then it is aligned on the A
frames and fastened in position using fitted bolts. |
 |
It is important to remember that the fitted bolts used to bolt the
entablature, A frames and Bedplate together are for alignment and location
purposes only. They are not designed to resist the firing forces which
will tend to separate the three components. This is the job of the tie
bolts.

entablature. Note also the diaphragm plate and the stuffing box housing. |
