1. Check the head valve ( A-Fig.1) and the seat ( B-Fig.1) conditions; if necessary, replace the valve or remake the
seat.
To clean the valves, proceed as follows:
•position the valve on a pillar drill. Before securing the valve to the drill, wrap tin foil around the drill-
valve contact area on the valve.
• Start the pillar drill.
• While the valve is turning, clean with a scouring pad.
• Remove the valve from the drill and wash completely.

This is a differential device with a diaphragm, located in the front part of each fuel manifold and set by the manufacturerto a pressure of 4.00 ± 0.05 bars.
The fuel under pressure coming from the pump pushes onto the diaphragm ( C-Fig.3 R I W K H G R Z Q À R Z Y D O Y H '
Fig.3 ), opposed by the calibrated spring ( % ) L J ).

Furthermore, through the pressure tap ( A-Fig.3), the vacuum in the intake manifold (where the injector shutter is
also located), operating on the regulator diaphragm, proportionally reduces the load from the calibrated spring.
In this way the pressure difference is kept constant between the fuel and the environment in which the injector is located (intake manifold) under all engine operating conditions.

Injectors
The task of the injector is to deliver the amount of fuel required for the engine operation: The fuel is injected into theintake duct, immediately upstream of the intake valves.
As the pressure differential is constant between inside and outside the injector (due to the regulator), the quantity of
fuel delivered, with the same electric power depends only on the opening time, established by the control unit.
The injector is the “top-feed” type with the fuel supplied from the rear of the body ( H-Fig.4), where the electric
winding ( ' ) L J ) is also located, connected to connector ( ( ) L J ). The needle ( % ) L J ), integral with the anchor
( C-Fig.4 ), is thrust against the seal seat by a spring ( I-Fig.4).
