Mechanical inspection of DEB
When the engine is run without the
valve covers, hot lubricating oil may
escape from the engine. Make sure
you are adequately protected.
}
When the engine or parts thereof are
opened, it is possible for dirt to
penetrate which can result in serious
damage to the engine. Therefore, the
engine should be cleaned
thoroughly before any parts are
opened.
Note:
If the DEB was removed, the DEB must first be
switched on and off several times with the engine
running to bleed the DEB and fill it with lubricating
oil.
1. Remove the valve covers.
2. Start the engine and run it at idling speed.
Note:
When the DEB is mechanically switched on,
the fuel injection is not switched off. Each
DEB should therefore be activated for as
brief a period of time as possible.
3. Use a small screwdriver to push the pin in the
centre of the solenoid valve downwards. The
DEB has now been activated mechanically.
4. Visually check whether the main and
operating pistons of the DEB move and/or
the exhaust valve is opened.
5. When the DEB is switched off, check
whether lubricating oil is discharged from the
control valves.
6. Fit the valve covers.
