Insert the O-ring on the inspection covers (pos. , Fig. 163)

2.2.5
Recovering the heads
If the insides of the piston chambers on the head show
clear signs of cavitation, due to incorrect pump feeding, it is
possible to recover the damaged head and avoid the need to
replace it.
In order to recover the head, perform the operations indicated
in Fig. 165 for LK36-40-45 and in Fig. 166 for LK50-55-60:
