Electrical Troubleshooting Procedures LTC Repair 6.7 Checking Engine Speed See Graphic: wc_gr001625, wc_gr001634, and wc_gr002441 Using either a photo (strobe) tachometer, a frequency meter (60Hz = 1800 rpm; 50Hz = 1500 rpm), or a vibration tachometer such as a Sirometer (a) (Wacker P/N 0053397), check engine rpm. Refer to the instrument instructions. If necessary, adjust engine rpm using adjusting screw [(b) Lombardini engines, (c) CAT engines]. No load engine speed should be 1850 rpm for 60Hz and 1550 rpm for 50Hz models. NOTICE: Do not adjust the engine speed to be higher than that listed above. The electrical components are frequency sensitive. Running at higher speeds will lead to component damage. Also check the condition of the engine air, fuel, and oil filters. Change the filters if necessary. See maintenance section. 76
