16. Change gearbox oil
The figure shows ZF 16 S 151 transmission.
- With the gearbox warm, take off the plug(s) (1) and
drain the oil into a specific container.
- The oil should be drained off taking care not to soil the
cross member beneath as it is near the outlet on some
types of gearbox.
- It is therefore wise to use a tool to convey the oil away.
- Pour in fresh oil through the hole closed by the plug (2)
(for the quantity, see under the FLUIDS heading of the
GENERAL section).
- Tighten the plugs to the required torque.

Remove the oil filter as follows:
- unscrew the screw (5) fixing the filter;
- take off the cover and filter (1);
- remove the cover from the filter and replace it. Take care
not to lose the magnetic pad (4) on the outer edge of
the filter, as it has to be repositioned on the new filter;
- check the state of the o-ring (2) and replace it, if
necessary;
- grease the o-ring (3) inserted in the assembly opening of
the new filter;
- couple the new filter with its cover and insert it into its
seat as far as it will go. Secure the screw (5).

- Screw the plugs back on and tighten them to the
required torque.
- Pour in fresh oil through the hole closed by the plug (7)
until oil comes out of the hole of plug (6) and screw the
plugs back on to the required torque.
(The filling quantity is given under the FLUIDS heading
of the GENERAL section.)
- Clean the gearbox oil vapour breather.

- With the gearbox warm, take off the plugs (1) and drain
the oil into a specific container.
- Remove the Intarder filter following the procedure
described in the above paragraph.
- Screw the plugs (1) back on and tighten them to the
required torque. Pour in fresh oil through the hole of
plug (3) until oil comes out of the hole of plug (2).
(See the FLUIDS table in the GENERAL section.)
- Screw the plugs back on to the required torque.
- Clean the gearbox oil vapour breather.
!
Have a short test run on the roads (at least one
minute at least 10 km/h), briefly operating the
Intarder just once (level 6) and then disengage it
(level 0). At the end of the test, stop the vehicle
without operating the Intarder. Stop the engine,
check the level again (plug 2) and top up, if necessary.

16. Clean gearbox oil bleed
The figure shows ZF 16 S 151 transmission.
Remove the oil vapour breather (1) and clean it thoroughly.
Then fit it back on, checking it is in the right position, and
tighten it to the required torque.

The lubricating oil has to be drained with the oil warm.
Place a container under the plug (1), remove the plug and
drain off the oil.
Fit the plug (1) back on, remove the plug (2) and pour the
required grade and quantity of lubricating oil in through the
hole. Remove the oil vapour bleed and clean it thoroughly.

11. Change front, middle or rear axle wheel
hub oil (where applicable)
For the wheel hubs with the cover illustrated in the figure,
proceed as follows:
- turn the wheel hub so as to bring the plug (1) downward;
unscrew the plug and drain off the oil into an appropriate
container;
- then turn the hub and take the hole closed by the plug
(1) back upward and replenish with fresh oil; for the
quantity, see CHARACTERISTICS AND DATA in the
“AXLES” section;
- screw the plug down to the prescribed torque.

Use no chlorothene based solvents to clean the
cover.
For the wheel hub with the cover illustrated in the figure,
proceed as follows:
- remove the plug (1) and draw up the oil with a suitable
string;
- fill the wheel hub with new oil (for the quantity and type
of oil, see CHARACTERISTICS AND DATA in the
“AXLES” section.
The oil level is checked through the window in the plug (1)
with max. and min. on the cover in a horizontal position.
10. Check steering box fixing and mounting
Check that the fastenings of the steering box and
mounting are tightened to the required torque.

- Set the vehicle unladen with its tyres at the required
pressure on level ground facing a light wall.
- Mark two crosses on the wall corresponding to the
centres of the two headlights.
- Turn the switch onto 0.
- Set the vehicle at 10 metres and turn on the low beam.
The distance between the crosses and the points P,
which correspond to the angle of the headlights, has to
be 12.5 cm.

arrows.
After removing the control belts (3 and 5), take off the screw
(7) and change the backstand (8).
Fasten screw (7) and tighten it to the specified torque.

The backstands are automatic and so no further
adjustments are planned after assembly.

Place the vehicle on a bridge.
Remove the draining plug (2) of the check module and drain
the transmission oil at operating temperature (71
° to 93°C).
Once the oil has been drained, refit the plug (2) to a tightening

following prescriptions.
Lubricate the new O-rings before assembly. Tighten the
screws to the prescribed torque.
Once assembly has been completed, make sure the oil
draining plug (2) is well tightened and then pour 18 litres of
Tutela GI/A oil through the filling pipe.
