1. General
For checking, dismantling, assembling and adjusting the injection valve, test
bench 94272 as well as test & calibration fluid has to be used (e.g. Shell Calibration
Fluid S.9365) complying with the data according to the following table:
Physical characteristics for test & calibration fluid:
Kinematic Viscosity ASTM D445
at 40 _C
mm
2
/s 2.6
Density at 15 _C
kg/m
3
ISO 12185 827
Pour Point
_C
ISO 3016 −27
Clean diesel oil (gas oil) can be used if no calibration fluid is available. The use
however is not recommended, if the injection valve will be stored and not directly
installed on the engine (corrosion reasons).
On some injection valves the leakage flow amount might be bigger than on others.
In case of the test bench flow is not sufficient to open the nozzle needle, a clean
additive-type crankcase (system) oil of the SAE 30 viscosity grade (for additional
data see 0750−1 ’System oil’ in the Operating Manual) can be used for testing
instead of the above mentioned fluids.
