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.
