3.38 CHECKING THE CLUTCH FLUID LEVEL

Hydraulic fluid is toxic and can 
therefore have a damaging effect on 
your health.
Hence avoid any direct or indirect 
physical contact.
As hydraulic fluid is also a corrosive 
fluid, it may damage the paintwork of 
the vehicle.
Avoid any contact between 
hydraulic fluid and paintwork.
Always use new and clean hydraulic 
fluid which has been kept in a sealed 
container and meets the 
specifications.
Hydraulic fluid which has absorbed 
water (from the ambient air) may 
have an adverse effect on the 
operation of the clutch system.
Avoid any contact with mineral oil.
Even one drop of mineral oil in the 
system will damage the seals. 

1.

Check that the fluid level is between the (A) 
and (B) marks when the cab is in the driving 
position.

2.

Mark (C) applies to fully tilted cabs.

3.

Hand tighten the reservoir sealing cap.

Note:
There is an air bleed vent in the cap that may 
be closed if the cap is tightened with too 
great a force.
If the air bleed vent is closed off, residual 
pressure will build up in the system.

3.39 INSPECTION AND ADJUSTMENT, CLUTCH WEAR INDICATOR

Checking the clutch wear indicator
1.

Visually check that the lock nut (12) makes 
contact with the housing. If the lock nut (12) 
no longer makes contact with the housing, 
the clutch plate is approximately 80% worn.

Note:
It is not permissible to remove the circlip, or 
to move the circlip over the pin. This is to 
prevent inaccurate indication.

Adjusting the clutch wear indicator
1.

Press the circlip (12) against the clutch 
servo.

Note:
It is not permissible to remove the circlip, or 
to move the circlip over the pin. This is to 
prevent inaccurate indication.

3.40 CHECKING THE GEARBOX FOR LEAKS

1.

Visually check the gearbox for leaks.

3.41 CHECKING THE CENTRAL AXLE OF THE TANDEM AXLE UNIT FOR LEAKS

1.

Visually inspect the central axle for leaks.

3.42 INSPECTION OF OIL LUBRICATED WHEEL HUBS FOR LEAKS

1.

Check the wheel hubs for leaks.

Note:
If leaks occur in the oil lubricated wheel hubs, 
the wheel hub should be refilled to the 
correct level - once the leak has been 
repaired, see chapter: "Draining and filling". 

3.43 CHECKING THE GREASED WHEEL HUBS FOR LEAKS

1.

Check the wheel hubs for leaks.

Note:
If there are serious grease marks on the brake 
disc side of the wheel hub, this could indicate 
excessive use of assembly grease on new or 
recently assembled wheel hubs.
On wheel hubs that have not been assembled 
recently, serious grease marks could indicate a 
leak in the seal (1). This means that the entire hub 
unit must be replaced.
Serious oil leakage on the driven rear axle hubs 
could indicate that the O-ring (2) is not sealing 
correctly.
If there is an oil leak the hub unit should be 
dismantled to remedy the problem.
