TM 9-2360-261-20-l Table 2-1. Unit Level Preventive Maintenance Checks and Services for M113A2 FOV Item Interval Item To Procedure Not Mission No. Be Capable If: Inspected 3 Semi- Idle Test CAUTION Annual Avoid lengthy engine idling . This causes coolant temperature to drop below operating tem- peratures and can shorten en- gine life. Run engine at 800 rpm for 3-5 minutes with range selector in 2-3 range and brakes locked until normal operating temperature is reached. Engine runs hot or rough. If outside air temperature is less than 85°F (29°C), normal operating tem- perature should be 160° to 200° F (71° to 93°C). If outside air temperature is greater than 85° (29°C, normal oper- ating temperature should be 160° to 23O°F (71” to 110°C). With range selector in N, engine should idle smoothly at 650 to 700 rpm. High or low engine idle speed is usu- ally caused by accelerator linkage be- ing out of adjustment. Adjust linkage if necessary (page 23-34). Rough idling is usually caused by faulty injector timing and rack setting, faulty injectors, or air in the injection system. Contact next higher level maintenance. Change 3 2-43
