Installation of 6V-3075 Dial Indicator (2) 6V-3075 Dial Indicator (4) Synchronizing pin
Put 6V-3075 Dial Indicator (2) with 5P-7263 Contact Point (3) in 5P-4814 Collet clamp (1) .
Install the dial indicator (2) and the collet in the threaded hole at location (Y). When the contact point seats against fuel stop lever (7), slide the dial indicator inward or slide the dial indicator outward until the dial indicator gives a reading of 0.00 mm (0.000 inch). Tighten the collet enough in order to hold the dial indicator in position.
Remove synchronizing pin (4). Slowly move the actuator terminal shaft in the "FUEL ON" direction until the flat face of fuel stop lever (7) is against the end of the fuel setting screw (5). When the linkage is held in this position, the dial indicator reading will be the present fuel setting.

Engine information plateNote: See the information plate on the engine for the correct fuel setting for full static load.
If the fuel setting is correct, remove the dial indicator. Return the synchronizing pin and the washer to the original locations.
Install the plugs at location (Y) and (Z) .
If the fuel setting needs adjustment, go on to "Fuel Setting Adjustment".Fuel Setting Adjustment
A mechanic with governor and fuel setting training is the ONLY one to make adjustments to the engine fuel setting.
Note: Before the fuel setting adjustment is made, check the fuel setting. Refer to "Fuel Setting Check".Refer to Illustrations 2 through 4.
Cut the seal wire and remove fuel setting cover (6) and the gasket. Loosen the locknut. While "Surface A" of fuel stop lever (7) is held against the
