TM 5-3805-262-34 2-5. FUEL SYSTEM TROUBLESHOOTING (CONT) MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION 1. FUEL INJECTION PUMP NOT OPERATING PROPERLY (Cont). Step 4. (Cont). Slightly rotate test bench drive by hand while observing plunger lift dial indicator until you get lowest dial indicator reading. When lowest dial indicator reading is obtained, roller tappet is at BDC; zero plunger lift dial indicator. Slowly rotate test bench drive by hand in a counterclockwise direc- tion as viewed from drive end until plunger lift dial indicator in- dicates port closure between 0.0847 to 0.0926 inch. Then, set test bench degree wheel pointer to zero. Watch plunger lift dial indicator and rotate test bench drive by hand until dial indicator indicates zero. Number 1 roller tappet will be at BDC. Remove plunger lift dial indicator and plunger lift device. Watch rack travel dial indicator and move control lever until a rack travel of 0.477 inch is obtained; lock control lever in this posi- tion. Turn test bench on but do not drive fuel injection pump. Set test bench for high pressure phasing. Watch test line for number 1 cylinder. There should be a steady flow of fuel from number 1 test line. Turn off test bench fuel flow. a. If there is not a steady flow of fuel from test line, turn off test bench and go to step 5 below. b. If there is a steady flow of fuel from test line, go to step 6 below. Step 5. Turn test bench on but do not drive fuel injection pump. Set test bench for high pressure phasing. Watch test line for number 5 cylinder. Rotate test bench drive by hand. There should be a steady flow of fuel from number 5 test line. Continue rotating test bench drive by hand. Fuel flow from number 5 cylinder should stop and fuel should flow from number 3 test line. a. If fuel does not flow from number 5 and 3 test lines, either fuel inlet port or internal fuel galleries of fuel injection pump are clogged. Disassemble fuel injection pump (page 3-140) and clean housing (page 3-148). b. If fuel flows from number 5 and 3 test lines, remove number 1 delivery valve holder and associated parts (page 3-145). Check parts for clogged or damaged condition. 2-53
