Maintenance & consumables
for the Cummins/Onan NT855| Item | Spec | Capacity | Part # | Interval | |
|---|---|---|---|---|---|
| Air filter | If the engine is equipped with an oil bath type air cleaner, fill to the level indicated with oil of the same viscosity as used in the crankcase. However, a non-detergent (straight mineral) oil is recommended. | — | 1000 hr | ||
| Fuel filter | — | 500 hr | |||
| Oil filter | — | 1000 hr | |||
| Battery | Batteries will self discharge very quickly when installed where the ambient temperature is consistently above 90°F, such as in a boiler room. To lengthen battery life dilute the electrolyte from its normal 1.275 specific gravity reading at full charge to a 1.225 reading. | — | 1440 hr | ||
| Belt | — | 1000 hr | |||
| Coolant | For units which use either a radiator or heat exchanger (city water cooled), fill the cooling system with clean soft water, The standard radiator and block capacity is 21 U.S. gallons. Use a good rust and scale inhibitor. If there is any possibility of a radiator cooled plant being exposed to freezing temperatures, use antifreeze with ethylene glycol base as instructed in the Cummins manual. | 80.63 L | — | 5000 hr | |
