HYDRAULIC EQUIPMENT
This equipment consists of internal and
external circuits.
A gear pump is source of pressure oil.
Oil is delivered from common filling of
the gearbox and axle drive.
HYDRAULIC PUMP
Hydraulic pump cannot be stopped. In
case that engine is running, the pump
works as well.
Pump type Delivered volume
UD 20 50 l/min
Pressure, generated by the pump in the
hydraulic system, is limited by a relief
valve to 18MPa.
FILTRATION OF HYDRAULIC OIL
The hydraulic pump sucks oil through the
suction cleaner that is installed on the
left side of the gearbox under the cabin.
The cleaner cartridge can be replaced
without discharging oil from the gearbox.
When replacing the filtration cartridge,
you cannot avoid leaks of oil from the fil-
ter body. It is necessary to catch it into a
clean container with volume approx. 10
litres. Return the leaked oil back to the
gearbox (in case of necessary replace-
ment out of the recommended interval of
replacement of the cartridge and oil).
