Disassemble the suction and outlet valve units, screwing a
sufficiently long M8 screw in such a way as to be able to reach
the valve plate and extract the valve guide from the valve seat
(Fig. 22, pos. ).
If the M8 threaded holes should not be present on the valve
guide, dismantling can be easily carried out by levering with
simple tools (Fig. 23).
Note. Before extracting from the seats, always unscrew the
handle code 27513400.
