General Information Section
Introduction
The Fuel Injection Equipment Test Stand (FIETS) is used to efficiently and accurately test all of Caterpillar's fuel injection pumps. These include forged body fuel pumps, compact fuel injection pumps, scroll fuel injection pumps, sleeve metering injection pumps, and 3000 Series fuel pumps.The maintenance and verification procedures in this Tool Operating Manual apply to 6V-7900, 6V-7901, 6V-7902, 6V-7903, 6V-9440, 1U-8212, and 1U-8213 Fuel Injection Equipment Test Stands.Assuring Accuracy
Obtaining accurate and usable results from the FIETS is only possible if the test stand is properly and accurately maintained. If the test stand is not regularly calibrated to factory specifications, the data provided may not be accurate. Test stand maintenance must include testing the quality of the calibration fluid, gauges, and calibration tubes, in addition to changing filters, tightening drive belts, and replacing worn parts.This Tool Operating Manual provides procedures to test, adjust, clean, and maintain the test stand in proper working order. The manual also contains forms to accurately record the history of the maintenance procedures.Remember, test results are only as good as the equipment used to test the fuel injection pump.Test Stand Repair Information
If the test stand needs more than general maintenance or adjusting, contact the original equipment manufacturer. USA and CanadaLucas Aftermarket Operations

Operation Section
Testing A Pump
Bench testing verifies the condition of the plunger and barrel as well as the cam profile. If the plunger and barrel is worn, the delivery rate will be low. Insufficient delivery rates can also be caused by worn cam lobes.Governor settings can also be verified and adjusted using the test stand. Refer to SEHS8200, "Caterpillar Fuel Injection Equipment Test Stand" for complete instructions on testing fuel injection pumps.TMI Data Specifications
Test specification data for newer Caterpillar fuel injection pumps can be found on the Technical Marketing Information (TMI) system. Refer to TMI Manual, LEBQ0724, for additional information on using TMI. Also refer to Tool Operating Manual, NEHS0594, "Using the TMI System to Retrieve Off Engine Injection Pump Test Specifications for the Fuel Injection Equipment Test Stand" for information on using TMI to obtain test specifications using the FIETS.Specific lines and master nozzles must be used for for testing pumps using TMI data.
