Rack sensor adjustment
1. Flange type rack sensor (rack sensor adjustment -5*20)
(1)These types of rack sensors do not need adjustment. Confirm the performance with the following procedures.
(2)Mount the rack sensor main body to the pump main body.
(3)Fix the pump lever at full.
(4)At supply voltage V1, pump speed N1 and rack position Ra, confirm that the amp's output voltage is Vist.
(5)Move the pump lever two or three times.
(6)Set again to full.
(7)Confirm that the amplifier output voltage is Vist.
(8)Fix the caution plate to the upper part of the rack sensor.
(For those without the caution plate instructions, make sure the nameplate of the rack sensor carries the "Don't hold here" caution.)
(9)Apply red paint to the rack sensor mounting bolts (2 places).

4. Install a new seal washer (6).Use 6V-4979 Carbon Stop Seal Tool (4) to install new carbon dam (5) on nozzle (2).7000 Series Nozzles
The part number for compression seal (3) is not the same for all nozzles. If the correct seal is not installed, the result will be high emissions. This is NOT acceptable.
Troubleshooting (Pencil-Type Fuel Nozzles Only)
A. To troubleshoot these nozzles, refer to the Troubleshooting Guide For Pencil-Type Fuel Nozzles located in this manual.B. Refer to Special Instruction SEHS8627 "Use of 8S-2245 Nozzle Cleaning Tool Group" for the correct procedure (according to the part number of the nozzle) in order to clean these nozzles. C. If VO is LESS than the specified value for a specific part number, DO NOT use the nozzle.Troubleshooting Guide For Pencil-Type Fuel Nozzles

Repair/Calibration Information For 5P-4150 Tester Group
For the repair and/or calibration of the 5P-4150 Tester Group, contact the manufacturer: U.S. Mail:OTC Division
SPX Corporation
655 Eisenhower Drive
Owatonna, Minnesota 55060, U.S.A.
Telephone:(507) 455-7000(800) 533-6127 Fax:(800) 955-8329Test Equipment Calibration
Caterpillar fuel nozzle and unit injector testers feature premium quality, liquid filled gauges for high accuracy and durability.Pressure gauges, in this application must be of high quality in order to provide accurate and consistent test results.To maintain this high degree of accuracy, gauge calibration should be checked at a MINIMUM of once a year. Additional information can be found in NEHS0631 "General Maintenance And Troubleshooting For Fuel Injection Equipment Test Stands (FIETS) And 5P-4150 Nozzle Tester". However, calibration should be checked at any time when the test results have become INCONSISTENT or if the gauge needle does NOT return to the 0 (zero) range when the test pressure is relieved.Calibration
Two methods are available for gauge calibration:* Method 1: Calibration by gauge manufacturer.* Method 2: 5P-8558 Pressure Gauge Calibrating Group. Additional information can be found in NEHS0631 "General Maintenance And Troubleshooting For Fuel Injection Equipment Test Stands (FIETS) And 5P-4150 Nozzle Tester".Calibration By Gauge Manufacturer (Method 1)
Certified calibration services are offered by Carrier - Oehler Company, a Caterpillar certified supplier of premium quality gauges.The Carrier - Oehler Company can promptly check and recalibrate gauges at a low cost.The Carrier - Oehler Company will also repair and recalibrate damaged gauges at a fraction of the cost of a new gauge.When sending gauges to Carrier - Oehler Company, include the following information:* Person or department that gauges and/or correspondence is to be directed to.* List the quantity and a brief description of the gauge(s) problem or the service requested.* Dealer name and address.* Telephone number.* Fax number. The Carrier - Oehler Company will advise you if repair costs exceed 50 percent of a new gauge.
