This component supplies the hydraulic pressure necessary to
keep the third axle wheels aligned on a straight.
Nitrogen pressure checking and recharging
Discharge the oil pressure from the circuit, working as
described on page 96, Figure 18.
Remove the protective lid (1).
Fit the adapter (4) to tool 99366918 (5). Fit tool (5) complete
with adapter (4) onto the accumulator (3).
Make sure that discharge valve (2) is closed.
Open the hydraulic accumulator nitrogen pressure checking
and recharge valve (3) by working on the knob (1) and read
the pressure on the pressure gauge.
Close the checking and recharge valve.
Discharge the nitrogen pressure from tool (5) by opening
valve (2).
If the reading on the pressure gauge is lower than 8.5 bar,
connect the tool to the nitrogen cylinder piping (3).
Make sure that the discharge valve (2) is closed, open the
checking and recharge valve by working on the knob (1).
Open the nitrogen cylinder and charge the hydraulic
accumulator (4) up to the required value of 8.5
±1.
Having charge the accumulator, close the nitrogen cylinder
and the checking and recharge valve.
Open the discharge valve (2) to release the nitrogen pressure
from the tool.
Finally, disconnect the tool, fit back the plug and the
protective lid.
