Hi, My name is***** will be glad to help. We can follow up as needed on here, Give me some time to review your information and follow up with my responses. Professionals are not employees of the site but users of the site and help on here as time allows in between jobs, family, etc. Response time can vary depending on my work load each day but I will always respond back on my next available login. Feel free to respond back at anytime if for any reason we seem to get separated, for status, etc.

Your 3116 needs to have the full synchronization procedure done which requires special dial indicators and tools to complete. You have to set control rack properly. If you do not have the injector synchronization tools, I recommend having somebody synchronize and do this for you as it's likely not even worth investing into the tools when you can just have somebody that knows the proper way to synchronize the rack and injectors.

What is your engine serial number prefix or in other words first three letters and numbers?

Use this procedure to determine if the governor is responsible for any of the following problems:

• Rough running

• Hunting

• Surging

• Idle instability

1. Determine the high idle rpm and record the rpm for future reference. Refer to Technical Marketing Information (TMI).

1. Remove the oil supply line from the rear of the governor. Check the screen at the oil inlet for plugging. Clean the screen, if necessary.

(1) Cover

(2) Dashpot adjustment screw

(3) Rear cover assembly

1. Remove cover (1) from the rear of the governor.

1. The dashpot adjustment screw has an orifice in the center. Determine if the orifice in the dashpot adjustment screw (2) is plugged or if the screw has backed out. Clean the orifice with a 0.05 mm (0.002 inch) or smaller wire, if necessary. Reinstall the adjustment screw. Tighten the adjustment screw. Stake the adjustment screw in order to secure the screw. Do not use thread lock compound to secure the adjustment screw. If the problem is not resolved, proceed to Step 5.

1. Remove rear cover assembly (3) from the governor.

(4) spring/">Spring seat

1. Remove the governor spring seat (4). Add one shim onto the front side of the spring seat. Reassemble the governor. Operate the engine at low idle in order to determine if the problem has been resolved. If the problem is still present, add an additional shim and check the engine performance again. If the problem is resolved, operate the engine until the normal operating temperature is reached. Reset the low idle and reset the high idle. If the problem is not resolved proceed to the Step 7.

Note: A maximum of three shims may be installed.

(5) Shutoff Assembly

1. Check the serial number from the Governor Information Plate. If the serial number for the governor is less than 100,000, install an improved shutoff assembly (5). Refer to Service Manual, SENR6454, "3114, 3116 & 3126 Engine Governors".

1. Check the governor for the following conditions:

   • Servo that is binding

   • Tight pivot shaft in the bearing block

   • Swivel that is binding

   • Sleeve that is binding

   • Plugged oil passages to the servo piston

Replace the governor if repairs do not resolve the problem and all other systems have been thoroughly checked.

The illustrations will not post to the page unfortunately.

I am mobile at the moment but when I get back to my office I will pull up some more information for you.

Refer to the Testing and Adjusting, "Governor (Type VII) - Adjust" section for the adjustment procedures.

   Note: Do not adjust the low horsepower setscrew during the high horsepower adjustment procedures. If the low horsepower setscrew is adjusted, the high horsepower setscrew will also need to be adjusted

Click the link below and also the one above. I'm still waiting for your serial number prefix as their is well over a page worth of serial number prefixes for this model engine.

This service manual contains instructions for servicing the 3114, 3116, and 3126 Engine Governors on the 1U-7326 Governor Calibration Bench. The final low idle speed may be adjusted with the governor on the engine. All other adjustments must be performed on this calibration bench.

Typical governor information plate

Governor information plate (1) is located on top of the governor. The information plate provides the following information:

• Serial Number and Type Code

   

• Group Part Number

   

• Production Codes

   

The information on governor information plate (1) and the physical appearance of the governor is used to identify the governor. The type code follows the serial number. There are seven different types of governors for the 3114, 3116, and 3126 Engines. The following information will aid in the proper identification of each of the seven types of governors.

Table 1

Governor Identification Chart

Governor Type Type Code Throttle Lever Components

Type I "A" Type I

Type II "B" Type I No Servo, 4 Flyweight's

Type III "C" Type I or II

Type IV "A", "0", "1" Type II

Type V "D" Type II Cast FRC Housing

Type VI (1) "D" Type II Dual Horsepower

Type VII (1) "D" Type II Dual Horsepower

( 1 )Both Type VI and Type VII Governors are variations of the Type V Governor.

Which governor type? For some reason that information did not make it to your question. As you can see there are 7 different types. Your type for MUI or mechanical injectors.

All seven of those types above are for mechanical injectors unfortunately. The serial number prefix will be very helpful so I can post the right one out of the seven. I have to do a road call for a few hours today so I will be in and out throughout the day.

(5) Inlet fitting for the fuel transfer pump from the fuel filter base

1. Remove the large O-ring seal from the front of the governor. Align the drive coupling on the calibration bench with the governor drive gear by rotating the governor until the two drive pins in drive coupling (1) engage with the governor drive gear.

1. When the drive pins engage with the governor drive gear, rotate the governor in order to align the mounting holes in the governor housing with the mounting holes in the governor calibration bench.

1. To fasten the governor to the calibration bench, use the same bolts and washers that are used to fasten the governor to the engine. If the governor mounting bolts are not available, use three 6V-5218 Bolts with three 9M-1974 Hard Washers .

1. Install fittings (2), (3), and (5) in the governor. Install fitting (4) if the governor is equipped with a fuel ratio control.

Note: Step 6 is optional. If the governor calibration bench can successfully perform the entire procedure, then the fuel transfer pump can remain in position on the governor.

1. Remove the fuel transfer pump from the governor housing. Refer to the Disassembly and Assembly, "Governor (Type) - Disassemble" section in this manual for additional information.

1. Connect line (8) from the filter base to fitting (5) for the oil inlet on the governor.

1. Connect line (6) from the fuel transfer pump to fitting (2) for the inlet fitting of the fuel transfer pump.

1. If the governor is equipped with a fuel ratio control, connect a regulated air supply (hand pump or squeeze pump) to the fuel ratio control. Turn on the regulated air supply in order to pressurize the fuel ratio control.

   Note: A regulated air supply of 140 to 210 kPa (20 to 30 psi) must be used to avoid damage to the fuel ratio control.

1. Install the pressure gauge that is supplied with the governor calibration bench on the quick disconnect fitting on the filterhousing for the lubricating oil.

   Note: Ensure that the fuel shutoff solenoid is latched in the RUN position. To latch the fuel shutoff solenoid in the RUN position, refer to the Systems Operation, "Fuel Shutoff Solenoid" topic in this manual. If the fuel shutoff solenoid is a nonlatching solenoid, remove the fuel shutoff solenoid with a 9U-5120 Spanner Wrench and plug the opening.

1. Place the 1U-8815 Indicator Contact Point on the stem of the 6V-6106 Dial Indicator Gp (18). Install dial indicator (18) into bracket (10). Adjust the position of bracket (10) so that the contact point on the dial indicator stem is positioned in the center of the clevis pin.

1. Refer to the TMI data for the governor test bench in order to determine the load stop settings for the governor. If the governor load stop settings are 9.00 mm or higher, refer to the Testing and Adjusting, "Setting the Governor Load Stop Dimension for More Than 9.00 mm" topic in this manual.

   Note: The calibration dimension is the reference point for all other adjustments that are performed on the calibration bench. The calibration dimension is normally 8.00 mm (0.315 inch). The initial calibration dimension must be correct. If a governor load stop setting of 9.00 mm (0.354 inch) or greater is required, an alternate calibration method must be performed in order to allow the dial indicator to read the extra travel.

1. Adjust the position of dial indicator (18) on bracket (10) so that the dial indicator reads 8.00 mm (0.315 inch). Tighten screw (19) in order to lock the dial indicator in position. Check the adjustment dimension and adjust the dial indicator, if necessary.

1. When the dial indicator remains at the 8.00 mm (0.315 inch) dimension, rotate the throttle lever clockwise toward the low idle position. Remove calibration pin (13) and the collar.

1. Turn the switch on the pump to the OFF position.

Note: For previously adjusted governors or for field return governors that need to be checked, refer to the appropriate Testing and Adjusting, "Governor (Type) - Check" section of this manual.

Note: If a new governor or a rebuilt governor requires a change of the settings, refer to the appropriate Testing and Adjusting, "Governor (Type) - Adjust" section of this manual.

Yes, that is correct. Anytime you disturb the settings on disassembly or assembly, it needs to be reset unfortunately.

Thanks for the update. Glad to hear that you get this resolved. I provided you information from the manual to give instructions on how to set up your governor.

Glad you got this resolved.

Anytime.
