1. General
The test bench 94272 and calibration fluid must be used for the tasks that follow:
D To do checks
D To disassemble
D To assemble.
The properties of the calibration fluid (e.g. Shell Calibration Fluid S.9365, Univar
Calibration Fluid 1487) are as follows:
D The density at 15_C is 827 kg/m
3
(ISO 12185)
D The kinematic viscosity at 40_C is 2.6 mm2/s (ASTM D445)
D The pour point is −27_C (ISO 3016).
If calibration fluid is not available, you can use clean diesel oil (gas oil). If clean diesel
oil (gas oil) is used, install the injection valve immediately after you complete the
checks.
Note: It is not recommended that diesel oil (gas oil) is used if the injection valve
is put into storage after these checks. The injection valve can get
corrosion.
On some injection valves the quantity of leakage flow can be more than others. If the
test bench flow is not sufficient to open the needle, you can use a clean additive-type
crankcase (system) oil of SAE 30 viscosity. For more data, refer to the Operation
Manual 0750, paragraph 2 System Oil).
