DESCRIPTION AND OPERATION
IN-LINE AIR FILTER - PRE EU3
3
MODELS
1. To modulator vent port
2. Filter element
3. To atmosphere
The in-line air filter is placed in the ventilation line from the EGR modulator. The modulator needs to be able to
vent to atmosphere in order to release the vacuum supplied to the EGR valve. The filter prevents contamination
entering the modulator via the vent port which could cause failure. The filter should be periodically changed in
accordance with the recommended service intervals. The filter is attached to the RH inner front wing, and is held
in position by a clamping bracket. The filter must be mounted vertically.
NOTE: EU3 models are not fitted with an in-line air filter. The ventilation line connects directly to
the air cleaner housing, where it vents to atmosphere.
