(1)Temporary idle lever position setting 1. Refer to the RLD type governor service manual (Publication no. EE13E-11083). (2)Idling spring adjustment 1. Refer to the RLD type governor service manual (Publication no. EE13E-11083). (3)Governor spring setting adjustment 1. Temporarily fix so that the governor shaft's guide screw B protrudes L2 (18 mm) from the end of the governor. 2. Set the control lever where it contacts the idle stopper bolt. 3. Increase the speed to Nh2+100 r/min or more. 4. Adjust using the two nuts C and D so that L1 = 0.3+0.5 mm and fix temporarily. 5. Adjust the protrusion L2 of the guide screw (B) so that the rack position at Nh1 is Rh1 and at Nh2 is Rh2. Then fix using the nut (E). 6. Further increase the speed and readjust the two nuts (C) and (D) so that there is no change in L1 until Nf+50 r/min. Then fix temporarily. [Advice] When L1 becomes smaller while speed is increasing to Nf+50 r/min, decrease speed by Nh2+100 r/min. Adjust so that L1 is even smaller, then again increase speed to Nf+50 r/min and confirm that L1 does not change. (4)Full load position setting 1. Refer to the RLD type governor service manual (Publication no. EE13E-11083). (5)Torque control spring adjustment 1. Set the control lever so that it contacts the full speed stopper bolt. 2. At the specified speed Nf, adjust using the full speed stopper bolt so that governing begins, then fix temporarily. 3. Increase the speed and adjust using the two nuts (C) and (D) so that the rack position Rg can be obtained at the specified speed Ng. Fix temporarily. 4. Decrease the speed and confirm the governing point (the beginning of governing point) at the specified speed Nf. 5. Set the speed at Nf-50 r/min. 6. Measure the torque control stroke (L1) and adjust to the specified stroke (L1) using the shim (A). 7. After completing shim adjustment, repeat the above adjustment using the two nuts. 8. After confirming the specifications Nf and Ng, fix the two nuts (C) and (D). 9. In this condition, increase the speed and confirm that R = 0 can be obtained. (6)Full speed lever position setting 1. Set the control lever so that it contacts the full speed stopper bolt. 2. At the specified speed Nu, adjust using the full speed stopper bolt so that governing begins, then fix temporarily 3. Increase the speed and confirm that the specified rack position Ru can be obtained. 4. Adjust using the full speed stopper bolt so that governing begins at the specified speed Nf, then fix. 5. Confirm that the result is the same as that in '(5) Torque control spring adjustment.' 6. Confirm that the control lever operating angle is within the specifications. (7)Rack limit adjustment 1. Refer to the RLD type governor service manual (Publication no. EE13E-11083).

Illustration 8 g00281837
Circuit breaker
(1) Reset button
(2) Disc in open position
(3) Contacts
(4) Disc in closed position
(5) Battery circuit terminals A circuit breaker is a switch that opens the circuit if the current in the electrical system is higher than the rating of the circuit breaker.A metal disc that is controlled with heat and a contact (3) will complete the circuit through the circuit breaker. If the current in the electrical system is too high, the metal disc becomes too hot. The heat causes a distortion of the metal disc which opens the contacts (2). Open contacts break the circuit. A circuit breaker that is open can be reset after the circuit breaker cools. Push the reset button (1) in order to close the contacts (4) and reset the circuit breaker.
Find and correct the problem that causes the circuit breaker to open.Correcting the problem before running the engine will help prevent damage to the circuit components caused by too much current.

(5) Air shutoff solenoid that is mounted in the air intake pipe.
The air shutoff solenoid (5) is located in the air inlet system on the top of the engine. When the air shutoff solenoid ("ASOS") is energized, the inlet air to the engine is mechanically shut off. The ASOS can be energized in the following two ways:
The ASOS is energized by the overspeed switch (OS).
The ASOS is energized by the emergency stop switch (ES).Fuel Solenoid (FS)

(5) Shaft
Illustration 12 g00293070
(4) Fuel solenoid (FS) that is mounted on the governor.
The fuel solenoid (FS) (4) is located on the governor or on the fuel injection pump of the engine. When the FS is energized, the spring (2) and the shaft (5) will cause the fuel rack to move directly or the fuel rack will move through the governor drive to the FUEL ON position. The FS must remain energized or the fuel flow will be stopped to the engine. 2301A Electric Governor Control
Illustration 13 g00293071
(1) 2301A Electric Governor Speed Control
Illustration 14 g00293069
Electric governor actuator (EGA) (2) and fuel solenoid (FS) (3). The components are mounted on the top of the engine.
The 2301A Electric Governor Control system consists of the following components:
2301A Control
Actuator (EGA)
Magnetic pickup (MPU)The 2301A Electric Governor Control system provides precision engine speed control. The 2301A Control constantly monitors the engine rpm. The control makes the necessary corrections to the engine fuel setting through an actuator that is connected to the fuel system.The engine rpm is measured by the magnetic pickup ("MU"). The magnetic pickup makes an AC voltage that is sent to the 2301A Control. The 2301A Control then sends a DC voltage signal to the actuator in order to adjust the fuel flow.The actuator changes the electrical signal from the 2301A Control to a mechanical output. The mechanical output of the actuator causes the linkage from the actuator
