Drive Axle Wheel Bearing Oil Level; Front And Tag Axle Wheel Hubs; Coolant Fluid Level - PREVOST H3-45 2023 Operator's Manual

8-10 Care and Maintenance
FIGURE 9: POWER STEERING RESERVOIR
FIGURE 10: POWERSTEERING FLUID TANK
Check fluid level as follows:
1. Stop engine;
2. Open compartment door;
3. Thoroughly clean the reservoir and its immediate
vicinity to protect the fluid from being soiled by
impurities;
4. Check fluid level through the clear bowl and
compare with the MIN & MAX marking affixed on
the bowl;
5. Remove the breather cap and top up level to "MAX"
mark;
6. Reinstall the breather cap.

DRIVE AXLE WHEEL BEARING OIL LEVEL

Drive axle wheel bearings are lubricated by the
differential oil. Maintain differential oil at correct
level to ensure adequate lubrication of drive axle
wheel bearings at all times.

FRONT AND TAG AXLE WHEEL HUBS

The unitized hub bearings used on the NDS
range of axles are non- serviceable items.
Bearings are pre-adjusted, lubricated and have
seals fitted as part of the manufacturing process.
The bearings are greased for life and there is no
need or facility for re-lubrication.

COOLANT FLUID LEVEL

The cooling system has two tanks; the surge tank
(A) and the recovery tank (B).
FIGURE 11: COOLANT TANKS ARRANGEMENT
Coolant level is checked through the recovery
tank (B) when the engine is cold (ambient
temperature). If the coolant level into the recovery
tank is lower than the MIN LINE, remove the
recovery tank filler cap and add coolant until
reaching the FULL LINE.
