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.

(1) 5P-0946 Box Assembly.(2) 1P-2375 Quick Connective Coupler Assembly.(3) 8S-4600 Quick Disconnect Nipple (two each)(4) 8S-4599 Quick Disconnect Coupling Assembly. Other nipples for gauge attachment: 2S-5244 Quick Disconnect Nipple, 1/4inch NPT External Thread.The 5P-8558 Pressure Gauge Calibrating Group consists of three gauges, each with 0.5 percent accuracy:Each gauge has a defined pressure range:* Gauge one...1100 kPa (160 psi)* Gauge two...4150 kPa (600 psi)* Gauge three...34,500 kPa (5000 psi)The two lower pressure gauges (gauge one and two) are protected from excessive pressure by two sensor valves. The sensor valves shut OFF the pressure signal to the gauges at a preset value.A separate source of pressure, such as the recommended 1U-5230 Pump Group
