Measure Injector Coil Resistance; Install Injectors In The Fixture - Hartridge HK900 Operating Manual

Operating Manual

4.3.3 Measure Injector Coil Resistance

If you wish to measure the injector solenoid resistance this should be done before installing the
injectors in the fixture. Connect the resistance measurement cable to the AE32, then press the []
button and follow the on-screen instructions (a series of dialogs will appear asking you to connect one
injector at a time to the resistance cable). When you press [OK] to go on to the next injector, the
resistance value will be transferred to the main screen.
NOTE Resistance measurement is only valid for solenoid coil injectors, not for piezo injectors.

NOTE: The height of the test rail is adjustable via the two screws in the central pillar. For the
majority of injectors the rail should be left in its lowermost position. For Delphi injectors

Figure 4.2: Testplan Menu
Figure 4.4 shows a general schematic of the injector
installation. The exact parts required will depend on the
injector type - full details are given in Technical Bulletin
195/11. Select the right parts for the injector you have and
mount as shown.
NOTE: Remove any sealing washers from the injector
nozzle and use the seals supplied in the relevant
Nosepiece Adaptor Kit.
The clamp block screws A should be tightened to a torque of
25Nm.
Tighten the main drawbar nut (24mm socket) to bring the
lower section of the fixture up to clamp the injector. Tighten
until you reach a dead stop (i.e. when the stop tube and
spacer are clamped between the upper and lower blocks) –
no torque setting is required.
NOTE: The clamping load is set by the distance D between
the upper and lower blocks.
D
injectors a 9kN clamp load is recommended,
therefore the 9kN Spacer NTA5002 should be fitted
unless advised otherwise.

Now connect the high pressure pipes from the rail to the
injectors, the backleak piping, and the electrical cable.
