0000001601 BOOST COMPENSATOR ADJUSTMENT
BCS adjustment procedure
1. At full boost pressure, set so that the full injection quantity is within the specifications (adjusting point).
2. Perform boost compensator intermediate operation point adjustment (pump speed N1, boost pressure P1).
3. When injection quantity at boost pressure P2 and pump speed N2 is not as specified, loosen nut (A) and adjust position of screw (B) so that injection quantity is as specified. The screw position should be within +-1 turn of initial position.
4. The nut tightening torque is T.

3. Set the control lever at the adjusting point. Position the dummy bolt against the lever and fix.
4. Assemble the potentiometer to obtain output voltage V1 at the fixed position.
5. After mounting the potentiometer, remove the dummy bolt.

Introduction
The 7C8966, 7C8972, 8N5651, 8N5887, 9N0495, and 9N5864 Fuel Injection Pump Groups (new), or the 0R0766, 0R0902, 0R0903, 0R2374, and 0R2385 Fuel Injection Pump Group [remanufactured - (reconditioning has been done to a used fuel injection pump and governor group to give the same quality as a new pump group)] are service replacements for the fuel injection pump and governor groups used on 3208 engines, according to the adaptability shown in the chart. These service groups have only those gaskets and seals that are needed to install the fuel injection pump and governor on the engine.Reference: Parts Manual, Service Manual, Engine Information Plate, Fuel Setting Information Microfiche, Fuel System and Related Information MicroficheDo not perform any procedure, outlined in this publication, or order any parts until you read and understand the information contained within.Service Group Chart
Removal and Installation
1. Remove the pump and governor from the engine. Refer to the Service Manual.
When a replacement fuel injection pump and governor is installed on an engine (or when replacement parts are put in a fuel injection pump and governor), use the information on the engine information plate and always check engine low idle speed, set point and the fuel setting dimension. These settings and dimensions must be checked and adjustments made by a mechanic that has the necessary training in fuel system maintenance. Before the fuel system checks and adjustment are made, remove the original factory fuel system seal. After all fuel system work has been completed, install your Dealer seal as a replacement seal. Refer to Fuel System and Related Information or Fuel Setting Information for additional specifications.
2. Put the new service pump group in a 2P8315 Bracket Assembly (1) so it will be easier to work on. Remove the shut-off solenoid and the solenoid ground wire from the old fuel system. Remove the fuel line fittings from the old fuel system. Install these parts in the same location on the new fuel system.3. Locate the engine serial number and write it down. Make reference to the Fuel Setting Information or Fuel System and Related Information to find the part number of the governor high idle spring that is needed for the engine. The same part number governor high idle spring given in the Fuel Setting Information, or the Fuel System and Related Information must be installed in the new service pump group. The 9L6508 High Idle Spring is already installed in the service pump and governor groups. The governor high idle spring needs to be changed only if the needed part number is different than 9L6508. If it is necessary to change the high idle spring, refer to the Service Manual. The part number of the low idle spring is 4N5663 and is the same for all fuel systems.4. A 4N0527 Overfueling Spring is installed in the service pump and governor groups. Refer to the Parts Manual to determine which overfueling spring is required. If the overfueling spring must be changed, refer to the Service Manual for the
