VENT CRANKCASE FILTER
Crankcase Ventilation is a system that was developed to
remove harmful vapors from the engine and to prevent
those vapors from being expelled into the atmosphere.
This is a very efficient way to reduce pollution as well as
engine oil consumption.
Crankcase vapors (red arrow) are sent into a specific
device. From there, light fumes are directed to the air
intake to be burned (velvet arrow), while heavy oil
vapors get into a filter trapping debris ( B ). Condensed oil
returns back to the crankcase (yellow arrow) by gravity.

The filter is made of a non woven fabric to avoid
introduction of flint in the engine.
REPLACING CRANKCASE VENT FILTER
The top of the crankcase filter is equiped with a sensor
poping up when the filter is full and needs to be replaced.
If the indicator has not surfaced, there is no need to
open the unit for inspection.
1. Open clamps ( A ) and remove the crankcase vent
housing ( B ).
2. While unit is opened, check that the inlet and outlet
ports are not cocked up, as well as the relevant ducts.
3. Remove old filter and discard it ( * ).
4. Install new filter into crankcase housing and snap it
into place. Make sure that the top O ring seal is in place
and in good condition.
5. Install housing and lock up side clamps.
6. Inspect bottom oil drain line for kinks, blockage, or
other damage.
( * ) Do not throw the used filter in domestic garbage bin.
Enquire with an authorized recycling center.
