106672-9684 ZEXEL 9 400 611 454 BOSCH INJECTION-PUMP ASSEMBLY 9400611454 1066729684

The following installation procedures are to be used in conjunction with Special Instruction, SEHS9173, "Installation of Automatic Ether Injection System (AEIS)". This instruction outlines the extra steps needed to install components of the MPPS system along with routing and clipping of harnesses.
Before starting the installation procedure, make certain that the machine disconnect switch is in the off position.Do not perform any procedure, outlined in this publication, or order any parts until you read and understand the information contained within.Reference: Service Manual, SENR4705-02 and Special Instruction, SEHS9173.Necessary Parts
The following parts list shows some part numbers in the deleted column. This means that these parts are called out on the Automatic Ether Injection System (AEIS) retrofit instructions but should not be ordered, since they are replaced by different parts for Multipoint Pressure Sensing (MPPS). This only applies if an AEIS retrofit is also being performed. Installation of 3E3778 Ether Control Group
* The 3E3778 Control Group is required for the MPPS system.If MPPS is being installed in conjunction with an AEIS retrofit, substitute the 3E3778 Control Group for the 9X5303 Control Group called out in the Automatic Ether Injection System Special Instruction, SEHS9173. Substitute a 3E3779 Film for the 9X4542 Film.If MPPS is being added to an existing AEIS system, check the electronic control box installed with the AEIS system to see if it is a 3E3778 or a 9X5303 Control Group. If a 9X5303 Control Group is installed, replace it with a 3E3778 Control Group and 3E3779 Film. Follow the control box installation instructions outlined in the AEIS installation Special Instruction. Be sure to install the 8R7105 Wire As. between the control and mounting plate to ground the control box to the frame. If an MPPS identification film is needed for a language other than English, refer to the following chart for the part number of the film for a specific language. Installation of 3E3530 Electronic Control Group [(PWM) Oil Pressure Sensor]
1. Remove the 6T4949 Oil Pressure Switch and the O-ring port adapter from the turbo oil adapter on the right rear of the engine (switch on the bottom port with 405-GY attached to it)2. Install a 3E5276 Adapter (1) in the port using a 3J7354 Seal (2) and a 6V4589 O-ring Seal (3).3. Install 3E3530 Electronic Control Group (4) [PWM Oil Pressure Sensor] onto 3E5276 Adapter (1).4. Using a 5P7854 Clip (5), loosely install the 3E3530 Control Group on the flywheel housing as shown using a 1T0720 Bolt (6) and 5P1075 Washer (7).Installation of Wiring Harnesses
Installation of 8E7966 Ether (Engine) Wiring Harness
* The 9N4537 Engine Harness on the AEIS is replaced with 8E7966 Harness Assembly.If MPPS is being installed at the same time as AEIS, substitute 8E7966 Harness Assembly for 9N4537 Harness Assembly called out in the AEIS installation Special Instructions.If MPPS is being added to an existing AEIS, disconnect the old 9N4537 Harness Assembly from the 9X0377 Control Group (water temperature sensor), 6T4361 Speed Sensor and the ether chassis harness.Install the 8E7966 Harness Assembly following the same installation
