2.2.2 Assembling the Head - The Valve Assemblies

Check the state of wear of the various components very carefully and replace them if

necessary. At each inspection of the valves, replace all the O-rings, both for the valve

assemblies and for the valve plugs.

Before repositioning the valve assemblies, clean their seats in the head, located by the

arrows (pos. 1, fig. 115), and then dry these seats completely.

Proceed with the assembly, following the reverse of the disassembly procedure shown in 2.2.1.

Assemble the inlet and outlet valve assemblies (fig. 116 and fig. 117), taking care not to reverse the springs

that were previously removed.

To facilitate insertion of the valve holder into the seat, place a pipe on the horizontal flat surface of the

holder (fig. 118) and use a mallet/striking hammer around the entire circumference.
