4.2 REMOVAL AND INSTALLATION, INJECTOR
}
Due to the presence of overpressure
in the fuel tank, fuel may run into the
cylinders when removing injectors.
Therefore, when removing injectors,
always first remove the tank cap.
Collect any fuel from the injectors.
Removing the injector
1. Disconnect the earth lead from the battery
terminal.
2. Remove the injector pipes as a set.
3. Remove the valve cover.
4. Remove the DEB.
5. Remove the attachment bolt (3) from the
injector clamp. To remove the injector and
the clamping piece, only use the special
tools (DAF no. 1329412) and
(DAF no. 0694928).
Note:
If during removal one or more copper shims
(1) remain in the injector sleeve, the injector
will be reinstalled in a higher position.
As a result, instead of spraying into the
combustion chamber of the piston, the fuel
will be sprayed onto the piston ring. This may
seriously damage the piston.
There will be inadequate sealing between
the O-ring (2) of the injector and the cylinder
head. Fuel leaking from the injector can flow
freely into the engine and dilute the
lubricating oil.
