2.2 REPAIRING HYDRAULIC PARTS
2.2.1 Dismantling the Head - Valve Units
Operations are limited to inspection or replacement of valves, if necessary and, however, at the intervals
indicated in the “Preventative Maintenance” table in chapter 11 of the use and maintenance manual. The
valve units are assembled vertically inside the head.
Operate as follows to extract them:
Unscrew the 8 M14x40 valve cover fixing screws (fig. 16).
Using the extractor hammer, p/n F26019400, extract:
A) Valve plugs (fig. 17)
B) Outlet valve units (fig. 18)
C) Valve bushings (fig. 19), combined with tool p/n F27513600
D) Suction valve units (fig. 20) Since the valve outlet units, being without threading for extraction,
should they remain glued in place on the head, use a simple tool as indicated in fig. 21.
