2.2.2 Assembling the Head-Liners-Valves
To reassemble the various components, reverse the operations listed previously, paying particular attention to
the correct assembly of the spacer for liners: the two as-cast discharges present on one of the two sides
must be facing towards the lower part of the casing (the pump support side) after assembly.
Head-liners: proceed with assembly and setting of the head affixing screws and then proceed with setting the
affixing screws for the liners.
For the tightening torque values and for the tightening sequence of the screws, follow the specifications given
in Section 3.
