2.2 Fluid End Repair
2.2.1 Disassembly of the head - valve units
The head requires preventive maintenance as indicated in the Owner’s Manual. Service operations are
limited to valve inspections or replacement if needed.
To extract the valve units proceed as follows:
Unfasten the 8 M12x35 cover screws, and remove the covers (fig. 30).
Failure to perform operations described in section 2.1.6 compromises the functionality of the pump
and operator safety.

Extract the valve units using the same slide hammer used for the valve plugs; it is applied to the M10 holes of
the valve guide (fig. 32).
