1. Aneroid compensator unit adjustment
(1)Select the push rod 2 to obtain L2.
(2)Screw in (A) to obtain L1.
2. Adjustment when mounting the governor.
(1)Set the speed of the pump to N1 r/min and fix the control lever at the full set position.
(2)Screw in the aneroid compensator to obtain the performance shown in the graph above.
(3)As there is hysterisis, measure when the absolute pressure drops.
(4)Hysterisis must not exceed rack position = h1.

Information:
Do not operate the machine if any guards or covers are missing or inadequately secured. Personnel could be seriously injured or machine damage may occur.
Observe the safe working load limits of all lifting and blocking devices and keep a safe distance from suspended/blocked loads. Personnel may be seriously injured or killed by falling loads.
Reference Section
Refer to Service Magazine, M0082326, "Diesel Exhaust Fluid (DEF) Contamination on C4.4 Machine Engines".Refer to Service Magazine, M0096547, "Diesel Exhaust Fluid (DEF) Pump Filter Maintenance on Certain C4.4 Machine Engines".Refer to Special Instruction, M0096185, "Diesel Exhaust Fluid (DEF) Pump Diesel Contamination Test on Certain C4.4 Engines".Problem
There have been instances of returned DEF pumps that have no fault found or indicating contamination.Resolution
Complete the form below and attach to any SIMSi claim in addition to a Product Status Report (PSR) from before any troubleshooting was performed or any diagnostic codes were cleared.
Use the electronic service tool to download a PSR with Histograms.
Enter the diagnostic codes that require troubleshooting: ___
Perform the correct troubleshooting procedure for any active diagnostic codes. Refer to Troubleshooting, Diagnostic Trouble Codes.
If the troubleshooting procedure requests that the DEF is tested for contamination or concentration , record the results in Table 1 and Table 2.
For other DEF-related troubleshooting procedures, follow the applicable troubleshooting steps and record the results in Table 3.
Table 1
DEF Contamination
Step Instruction Completed Result Units
1 Perform the test procedure for DEF contamination. Refer to Systems Operation, Testing and Adjusting, Diesel Exhaust Fluid Quality - Test.
2 Compensator measurements. Refer to Special Instruction, M0096185, "Diesel Exhaust Fluid (DEF) Pump Diesel Contamination Test on Certain C4.4 Engines".
Diameter (A) mm
Length (B) mm
3 If contamination is present, confirm that DEF system has been flushed. Refer to Systems Operation, Testing and Adjusting, Diesel Exhaust Fluid Tank - Flush
Table 2
DEF Concentration
Step Instruction Completed Result Units
1 Perform the test procedure for DEF concentration. Refer to Systems Operation, Testing and Adjusting, Diesel Exhaust Fluid Quality - Test. %
2 If the DEF concentration is out of specification, confirm that the DEF tank has been drained and filled with the correct specification of DEF. Refer to Operation and Maintenance Manual, Diesel Exhaust Fluid - Fill.
