How to remove and to fit an atomiser
How to remove
Warning! The combustible material of some components of the engine (for example certain seals) can become
extremely dangerous if it is burned. Never allow this burnt material to come into contact with the skin or with
the eyes.
Cautions:
• Atomisers must be removed and fitted by a person with the correct training.
• Do not allow dirt to enter the fuel system. Before a connection is disconnected, clean thoroughly the
area around the connection. After a component has been disconnected, fit a suitable cover to all open
connections.
1.
Release the atomiser cover setscrews (AD1) and remove the atomiser cover (AD2).
2.
Release the fastener (K3) and remove the breather pipe (AD4).
3.
Remove the fuel leak-off hose from the conn ection (AE2).
4.
Remove the union nuts of the high-pressure pipe from the atomiser (AE1) and from the fuel injection pump.
Do not bend the pipe. If necessary, remove the pipe clamps. Fit a plastic cap to cover all open connections.
5.
Remove the setscrew (AE3) and remove the clamp (AE4) from the cylinder head.
6.
Remove the atomiser and its seat washer (AF1) from its recess in the cylinder head.
Caution: Remove and discard the seat washer (AF1). If the original seat washer remains in the recess, the
nozzle protrusion will be incorrect when a new seat washer is added.
