Crankcase ventilation
The engines have ventilation devices to prevent over-
pressure and to disperse diesel fumes, water vapor and
other gaseous products of combustion.
On the TAMD162C and TAMD163A the crankcase gas-
es are ventilated by transfer from the engine compart-
ment via a pipe connected to the cylinder block.
On the TAMD163P there are two replaceable paper fil-
ters for crankhouse ventilation. These separate any oil
mist before the gases are led out. Any oil is returned to
the oil sump by a drainage hose.
The filter holder on the TAMD163P is installed on the
right side of the engine and connected to the air cleaner
(ACL). On the filter casing is also a relief valve which
opens if the pressure in the crankcase becomes too
high due to a blocked filter. If oil mist is escapes from
the relief valve then the filter must be replaced.
Alternatively the crankcase ventilation emissions can be
removed from the engine compartment by a hose in the
same way as for the TAMD162C, -163A. A pipe bend
with hose mounting is supplied with the engine for this
reason. This can be installed on the rear inspection
hatch on the right of the engine instead of the standard
crankcase ventilation device.

Air Cleaner (ACL)
– The TAMD163A and TAMD163P engines have a dry
filter with a filter element (disposable) of folded
paper.
– The TAMD162C engine has two air cleaners (ACL)
which are replaceable as a unit.
The air cleaner prevents harmful particles from being
sucked into the engine. A blocked air cleaner (ACL) re-
sults in reduced engine performace, incorrect fuel/air
mixture, incomplete combustion and smoke in the ex-
haust. A pressure drop indicator is located on the air
cleaner (ACL) unit. When the indicator shows all red on
an engine which is not running the air cleaner must be
replaced with a new one.
