Oil Supply - Mercedes-Benz GLK-Class Service Manual

Oil exchange at vehicle standstill
1 Oil feed via oil return line from transmission cooler
2 Through-hole to side output chamber
3 Side output chamber
Because of their integrated design, the transfer case
and automatic transmission have a common oil
system.
Oil is fed from the oil return line of the transmission
cooler to the transfer case via a separate feed line on
the housing of the automatic transmission. The oil
feed is limited to approx. 100 ml / min by a throttle in
the connector of the oil line.
There is an oil sump in the chamber of the side output
which is regulated to a constant oil level of max.
700 ml. If the oil level rises above 700 ml when the
vehicle is at a standstill, the oil drains off into the auto-
matic transmission via the central tapered roller
bearing.
