Hydraulic fluid cooler
The oil radiator is installed behind the diesel engine (Fig. 82).
The left part contains hydraulic oil; the right part is intended
for cooling for the engine. Should the loader get too hot dur-
ing long drives on the road or at high outside temperatures,
check whether the fan‘s V-belt is taut and in good condition
and whether the radiator air flow is blocked.
Ventilation filter / hydraulic fluid filler neck
The ventilation filter is located on the hydraulic fluid reser -
voir item 1 (Fig. 83). It ensures that the hydraulic reservoir
is ventilated and exhausted when the hydraulic fluid level
fluctuates. The air filter contains a filter element which pre -
vents dust and dirt from penetrating and oil spillings from
escaping. The air filter has a valve that keeps the reservoir
pressure at approx. 0.5 bar (7 psi). This pressure will escape
if the hydraulic fluid filler neck is opened.
Replace the ventilation filter after 1000 operating
hours.
