20. Use 6V2105 Rack Adjustment Tool Group (17) to turn Fuel Setting Screw (20) and/or Full Torque Adjustment Screw (21) the amount necessary to get the correct adjustment dimension. Be sure to tighten the locknut for each adjustment screw, after adjustment is complete.21. Make reference to step (16) to check each adjustment that was made. Make any corrective adjustments that are necessary. If adjustments are made, there is a zero tolerance for both the Fuel Setting dimension and the Full Torque Setting dimension. If the adjustment procedure is being done with the fuel system on the engine and it is difficult to see the adjustment screws, use outer edge (D) of the opening in the governor housing as a guide to put 6V2105 Rack Adjustment Tool on the Fuel Setting Adjustment Screw. Use inner edge (E) as a guide to put the 6V2105 Rack Adjustment Tool on the Full Torque Adjustment Screw.22. If the fuel injection pump and governor is equipped with a fuel ratio control, refer to Governor Linkage Adjustment For Fuel Ratio Control to check linkage adjustment. After adjustment is complete, remove compressor assembly (13), adapter (10), dial indicator (5) and dial indicator bracket assembly (3). Install the plugs and covers that were removed from the pump and governor.Governor Linkage Adjustment for Fuel Ratio Control -3406 Engines
Governor adjustment for the fuel ratio control can be done with the fuel injection pump and governor either on, or off the engine. Adjustment of the fuel ratio control is done dynamically. Refer to the Service Manual for the correct procedure. If the correct dynamic adjustment cannot be obtained, use the following procedure to do a check/adjust of the internal governor linkage.If the governor adjustment tools are already installed on the fuel injection pump and governor, start with the procedure in Step 13. If it is necessary to install the governor adjustment tools, start with Step 1 that follows. 1. Remove cover (1) from the side of the fuel injection pump housing. Remove plug (2) from the timing pin hole. 2. Install 5P4814 Collet (2) on 8T9198 Bracket Assembly (3). Install bracket assembly (3) on the fuel injection pump housing as shown.

Put 9S8903 Contact Point on 6V2030 Extension (7), then install the extension on dial indicator (69). The 9S8903 Contact Point will not go through the collet, so it must be installed after the dial indicator stem is put through the collet.4. Tighten collet (2) just enough to hold the dial indicator. 5. Remove the shutoff solenoid if so equipped, or the cover, and install 6V6151 Adapter (8) in its place. Move governor control lever to SHUTOFF position.6. Put 6V4186 Timing Pin (9) in the hole where plug (2) was removed. Push the timing pin IN until it comes in contact with the fuel rack. 7.
