Check of Accumulators:
4. Measuring the nitrogen pre-pressure canonly be done with
stopped engine and pres-sure-free lubrication system.
Stop both oil pumps. Close the inlet valveand open the
equalizing valve on the re-spective lubricator.
The nitrogen pressure in the inlet accumu-lator (0.7 litre) can
be checked without dis-mounting the accumulator. For use of
thepressure setting tool, see Step 5.
5. To measure the nitrogen pressure in theoutlet accumulator
(0.16 litre), the accumu-lator or the lubricator with
accumulatormust be dismounted. See Procedure 903-2.2.
For nitrogen pressure in the accumulators,see Data.
6. Use of Pressure Setting ToolAssemble the pressure setting
tool asshown in Figure 5, and mount the reducingvalve on the
nitrogen cylinder. If necessary,use a threaded adaptor.
Mount a 0-60 bar pressure gauge on the fill-ing valve when the
inlet accumulator (0.7 li-tre) is to be checked, and a 0-10
barpressure gauge when the outlet accumula-tor (0.16 litre) is to
be checked.

7. Before mounting the filling valve on the ac-cumulator, check
that the accumulator topis clean.
Mount the filling valve on the relevant accu-mulator with the
union nut. Check thatvalves C and F are closed.
Loosen the plug screw in the accumulatorusing a square drive
handle in socket E.
It is now possible to read the actual nitro-gen pressure in the
accumulator on the dialgauge on the filling valve.
8. If the accumulator needs to be refilled withnitrogen, open
valve A and increase theoutlet pressure from valve C on spindle Bto
1-2 bar above the pressure stated in Da-ta.
Open valve C until the accumulator is filledto the correct
pressure.
Close valve C and tighten the plug screwwith socket E to the
torque stated in Data.
Release the pressure in the filling valve atbleed screw F.
Unscrew the filling valve from the accumu-lator. Retighten the
plug screw to the torquestated in Data. Remount the
accumulator.
