• If the total weight for the combination exceeds
80 ton and the ambient temperature is above 30°C
for more than 1 month per year, the oil change
intervals shall be halved.
Replenishing oil level in gearbox
When the oil level in a gearbox is too low, it must be
topped up with oil. The following then applies:
• If the same oil is used to top up the gearbox as the
one already in the gearbox, there is no limit to how
much oil can be filled or how many times the oil
level can be replenished.
• If approved oil other than the one already in the
gearbox is used for topping up, then no more than
one litre may be used. This applies regardless of
how many times the oil is topped up to the correct
level. If more oil needs to be added, carry out a
complete oil change instead
Oil and filter changes after a repair to the
gearbox
If a component has been repaired or renovated, or if
the gearbox has been opened, an extra oil and filter
change must be carried out. This change must be
carried out at 10,000 km or 4 weeks, whichever is first,
after a component has been repaired, overhauled or
opened. When the extra oil and filter change has been
completed, the component's normal service
recommendation applies.
Checking the oil level
1
Remove the sound baffle, if fitted, from
underneath the gearbox
2
Check that the oil level is between the centre and
the maximum level on the transparent level plug
in the gearbox (A) (maximum and minimum oil
level, see picture)
3
Top up with oil as necessary, but first clean
round the filler plug (B)
