NOTE 1: Remove the existing green wire from pin 167 on the SCB2 and connect it to the green
wire on the multi-core cable. Connect the yellow wire from the cable to SCB2 pin 167.
NOTE 2: Remove the existing black wire from pin 26 on the SCB2 and connect it to the brown wire
on the multi-core cable.
Connect the white wire on the multi-core cable to SCB2 pin 26.
The electrical circuit diagram is given in Figure 3.5
NOTE:
The A182A175 interlock connector MUST be permanently plugged into the EXT1 connector to
enable normal AVM2-PC testing. The connector is replaced by its equivalent on external
systems (EUI and Common Rail kits) when non-standard AVM2-PC testing is required.
The HB418 kit can be distinguished from the original AE33 kit by different colour labels for
EXT1/EXT2.
The HB418 EXT1/EXT2 labels are BLACK letters on WHITE background.
2.2 Installing the Filter Assembly (HB378 & Machine No. <2285 Only).
Specific Equipment/Material Required

drill diameters: 6mm, 12mm, 30mm
The filter is installed outside the machine on the rear panel, with hoses going through the rear panel
into the machine, as shown in Figure 2.2. Figure 2.3 shows the rear view of the AVM2 upper rear
panel. If the AVM2 already has the filer mounting holes pre-drilled, start at point 3.
1. Remove the machine left-hand top panel to access the fuel tanks. Cover the tanks to prevent any
metal shavings going into the test oil or lube oil.
2. Mark out and drill new holes in the rear panel as indicated in Figure 2.3. File off any sharp edges.
3. Remove the hose assembly currently connected between the fuel pump and the pressure control
valve. This hose is no longer required.
4. Offer the filter assembly up to the machine from the outside, see Figure 2.2, passing the 2 hoses
through the 2 larger holes. Secure the filter-mounting bracket to the rear panel using the four M5
nuts and washers provided.
5. Feed the filter inlet hose up around the back of the pump and motor and connect onto the test oil
pump outlet.
6. Connect the filter outlet hose to the pressure control valve inlet.
7. Ensure all hydraulic connections are secure. Switch on the machine, start the test oil pump, and
check that there are no leaks in the circuit.
