Damage to the intake funnel after the installation process
The intake funnel must not come into contact with rotating or moving parts
after it is installed.
Premature contamination of the oil mist detector by splash oil
The intake position of the intake funnel must be outside areas with direct
splash oil.
Explosion in the crankcase
There is a risk of serious injury, including death, from explosion in the crankcase as a
result of incorrect assembly of the engine wall connection.
Loosening or removing the intake line from the engine wall connection is only
allowed when the engine is switched off, as an explosive atmosphere can
escape from the engine and lead to a risk of explosion.
Premature contamination of the oil mist detector
The intake funnels must be installed according to the customer drawing and
always aligned vertically and with the opening pointing towards the bottom of
the crankcase.
The allowed assembly tolerance is +/- 3 degrees deviation from the horizontal
alignment.
Blockage of the intake funnel
Constant flooding of the intake funnel with splash oil (caused by the rotating
crankshaft) negatively affect monitoring of the applicable crank segment and
must always be avoided.
Recommended installation for the engine wall connection, as shown in the figure below:
