Maintenance & consumables
for the Cummins/Onan LSG-423 (Turbocharged)| Item | Spec | Capacity | Part # | Interval | |
|---|---|---|---|---|---|
| Air filter | The engine air intake components should be checked at the interval indicated in Table 5-1. The frequency of cleaning or replacing air cleaner filter elements is primarily determined by the conditions in which the genset operates. The standard air cleaner contains a paper cartridge filter element which can be cleaned and reused if not damaged, or discarded and replaced. | — | 90 hr | ||
| Fuel filter | Check for dirty fuel filter and replace if necessary (see Maintenance section). | — | |||
| Oil filter | Spin off oil filter and discard it. Thoroughly clean filter mounting surface. Apply a thin film of oil to filter gasket and install new element. Spin element on by hand until gasket just touches mounting pad and then turn an additional 1/2 to 3/4 turn. Do not over-tighten (Figure 5-2). With oil in crankcase, start engine and check for leaks around filter element. Retighten only as much as necessary to eliminate leaks but do not overtighten. | — | 200 hr | ||
| Battery | Check the battery connections to make sure they are clean and tight. A light coating of non-conductive grease will retard terminal corrosion. | — | |||
| Belt | An improperly adjusted fan belt can cause engine overheating and insufficient battery charging. Push on the fan belt in the middle and check that it deflects no more than 0.5 in. (13 mm) under a load of 15 lbs. (67 N). If belt is loose, loosen the two bolts on the battery charging alternator and adjust until proper tension is obtained. Retighten alternator bolts after adjustment. | — | |||
| Coolant filter | — | ||||
| Oil | Check the engine oil level during engine shutdown periods at the intervals specified in the Maintenance Table. The dipstick is stamped with FULL and ADD to indicate the level of oil in the crankcase. For accurate readings, shut off the engine and wait approximately 10 minutes before checking the engine oil level. | — | |||
| Spark plug | Remove the spark plugs and inspect for damaged or cracked insulators, worn electrodes, damaged gaskets or excessive carbon deposits. Replace the spark plug if any of these conditions are noted. | — | 90 hr |

Reduce load if possible by turning off non-critical loads. b. Check air inlets and outlets and remove any obstructions to airflow. 2B. Indicates engine oil pressure has dropped to 30 psi (207 kPa). If generator is powering critical loads and cannot be shut down, wait until next shutdown period and then follow step 4. If engine can be stopped follow procedure in Steps 3 and 4. |
| ENG TEMP | Hl ENG TEMP lamp lights. Engine shuts down. | Engine has overheated (engine temperature has risen above 215°F/102°C) or coolant level is low. | A. Check coolant level and replenish if low. Look for possible coolant leakage points and repair if necessary. b. Check for obstructions to cooling airflow and correct as necessary. c. Check for a slipping fan belt and tighten if loose. d. Reset control and restart after locating and correcting problem. Contact an authorized service center if none of the above. |
| LO OIL PRES | 4, LO OIL PRES lamp lights. Engine shuts down. | NOTE: See also step 5. a. Check oil level, lines and filters. If oil system is OK but oil level is low, replenish. Reset control and restart. Contact an authorized service center if oil pressure is not in the range of 40 to 65 psi (275 to 448 kPa). | |
| OVERCRANK | 5. OVERCRANK lamp lights and engine stops cranking. | A. Check for empty fuel tank (LPG Vapor), fuel or leaks, or plugged fuel lines and correct as required. | |
| LO OIL PRES | Engine runs, shuts down, and LO OIL PRES lamp lights. | B. Check for dirty fuel filter and replace if necessary (see Maintenance section). c.
