Tested control in the A-M valve zone
2.1 Check that the support surfaces of the A-M valves on
the head do not show any sag due to the "floating" of
the valves themselves.
2.2 Check that the diameters where the O-rings work
do not present abrasions or grooves due to the
passage of the liquid caused by leaks of the O-
Rings or the valve seat gaskets.
2.3 In case the problems indicated in points 1.3 - 2.1 - 2.2 are found, the head and / or the
covers must be replaced.
3.0
Reassembly
3.1 Replace all O-Rings gaskets which must first be
thoroughly lubricated with grease with the
exception of the pumps with surface treatment of
cataphoresis or lamination.
