Change retarder oil
The oil should be changed every 120,000 km if single-
grade oil is used, 180,000 if synthetic oil is used.
1. Activate the retarder fully (stage 5) for about 5 seconds.
Repeat twice. Disengage the retarder and turn off the
battery master switch.
2. Unscrew the oil drain plug (4) from the bottom of the re-
tarder while the oil is still warm. Drain off the oil.
3. Unscrew the plug for the oil pan blocking valve (5),
which is located on the bottom of the retarder at the rear.
Drain off any leak oil.
Note that the plug (6) in the bottom of the heat exchanger
is for draining
coolant
.
4. Fit a new sealing washer to each plug. Tighten the large
plug to 150 Nm and the small one to 66 Nm.
5. Measure up exactly 6 litres of oil. Fill either through the
filler hole on top of the retarder (3), the dipstick hole (1)
or the level hole (2) on the left-hand side.
6. Check the oil level as described on the previous page.
7.
NB!
Directly after changing oil: Engage the retarder in
stage 2 at least three times so that the oil will be distrib-
uted to all the bearings and seals.
It is extremely important to have the correct oil level in
the retarder as the oil directly affects the braking capac-
ity of the retarder.
