TM 9-2910-226-34 Table 3-3. Typical Test Stand Accessory Kit d. All fuel injection pump assemblies, including fuel density compensator where applicable, shall be tested and adjusted on the fuel metering and distributing pump test stand prior to assembly on an engine or returning the pump assembly to stock. e. Depot overhauled pump assemblies shall be tested in accordance with paragraphs 3-51, 3-57, and 3-58. f. Repaired pump assemblies shall be tested in accordance with paragraphs 3-51 through 3-58. g. Pump assemblies removed from engines shall be tested in accordance with paragraphs 3-51, 3-57, and 3-58 to determine if pump repair is necessary. If repair is necessary, follow procedures in f above. 3-51. Installation of Fuel Injection Pump on Test Stand. a. Remove the fuel injection pump drive gear and hub (if on pump to be tested). b. Install adapter ring, Part No. 11020376, on the fuel injection pump. Torque tighten the three mounting bolts to 27-35 foot-pounds. c. Install fuel injection pump and adapter ring on the test stand adapter bracket, Part No. 11020392. Torque tighten the four mounting bolts to 27-35 foot-pounds. d. Lubricate the adapter ring oil seal and install the test stand pump hub, Part No. 11020384, and Woodruff key on the injection pump shaft and secure with retaining nut and lockwasher. Torque tighten nut to 65-70 foot-pounds. NOTE Do not remove any elbows or fittings from the pump. Fabricate necessary connections and fittings to install pump on the test stand. e. Lubricate the test stand rails with test oil and place the fuel injection pump and bracket on the rails. f. Position the fuel injection pump on the test stand drive coupling allowing a minimum of 1/16 inch clearance between the hubs. Clamp pump bracket securely in position. g. Improvise a manifold composed of a 3/8 in. flare tube to ¼ in. 45-degree pipe elbow (G, fig. 3- 163), ¼ in. pipe tee (H), ¼ in. pipe to ½ in. flared tube adapter (J), and ¼ in. pipe to ¼ in. flare tube adapter (K) (on all pumps except code G). On code G pumps only, install improvised adapter manifold into hydraulic head inlet fitting after hydraulic head port closing test, delivery valve test, and hydraulic head leak test. 3-52. Preparation for Hydraulic Head Tests. a. Disconnect density compensator overflow line at pump overflow valve. b. Remove overflow valve and plug openings with ¼ in. and 1/8 in. pipe plugs. c. Remove density compensator to hydraulic head fuel line. d. Position the nozzle tester on the right corner of the test stand (fig. 3-164).
