Most generators use a vented lead-acid battery to supply power to electronic controls and the starting system. Proper maintenance is required to ensure that your battery reaches its normal useable life. Typically, we recommend replacing emergency standby generator batteries every 2-3 years to ensure your emergency system is reliable during utility outages. Because Emergency Standby Generator batteries are used in stationary applications, the testing, maintenance, and replacement recommendations are different than typical automotive recommendations. A good source for battery maintenance procedures is the IEEE Std 450-2002 manual, which defines the IEEE (Institute of Electrical and Electronics Engineers) Recommended Practice for Maintenance, Testing, and Replacement of Vented Lead-Acid Batteries for Stationary Applications. Don't let poor battery maintenance and overdue useable battery life prevent your generator from providing power during an emergency!
We always use new replacement batteries and return the old batteries to our distributor for recycling!
Hoses are used on many components of every engine. They carry liquids (fuel, coolant, and oil), and gases (liquid propane and natural gas).
Hose should be replaced:
• When you replace a water pump
• When you replace a thermostat
• Every four years of service
• Anytime you notice damage or leakage
Some causes of hose failure are:
There is a difference between Light Duty Automotive Coolant and Heavy Duty Diesel Engine Coolant! Industry experts estimate that over 40% of a heavy-duty engine's downtime is related to coolant system problems, virtually all of which is preventable with proper preventative maintenance! To reduce engine downtime and lost revenue, heavy-duty/industrial engines should use a coolant specifically formulated for use in diesel engines. This type of antifreeze is referred to in the industry as a "low silicate" antifreeze.
Heavy Duty engine coolant requires a "pre-charge" of a supplemental coolant additive (SCA) added to it. SCA's contains additives not included in the low silicate antifreeze, such as nitrite, that are essential to trouble-free operation of diesel engines.
Some symptoms of using or mixing improper Diesel engine coolant are:
We only use Fully Formulated coolant in Diesel engine coolant systems.
Timing & Fan Belts
Belts should be checked for improper wear, improper tension, and physical condition during every maintenance inspection. The accessory belt plays an important role in engine and generator cooling by spinning the water pump and cooling fan. It also powers the engine Direct Current (DC) voltage alternator, which maintains the battery for engine and control functions.
Diagnosing spark plugs is really pretty straight forward, based on the appearance of the electrode end of the spark plug. A good technician can determine a lot about how an engine is operating, based on the appearance of the spark plug. Some engine conditions that can be determined by reading a spark plug are:
Fuel & Oil Filters
Modern oils play vital functions in protecting engines, especially in a heavy-duty situation. Lubricating oil acts to reduce friction and wear, cool engine parts, seal combustion chambers, clean engine components and inhibit corrosion. These functions are carried out by special additives in the oil, which complement the action of the oil itself. The protective action of the lubricating oil and its additives are supported and balanced by the work of the lube filter.
Oil & Fuel filters, particularly those designed for heavy-duty applications, have the sole purpose of keeping damaging contaminants away from sensitive engine parts.
Filters trap oil & Fuel contaminants!
Some particles adhere to filter media as the Oil & Fuel flows through the filter. Such particles attach themselves to the media surface without plugging up the media pores.
Air is necessary for successful combustion in your engine. There are operational signs that an air filter has become completely plugged. The engine begins to lose power, and fuel consumption increases. Black smoke may blow from the exhaust. Continued operation with a plugged air filter may very well damage the engine.
It is impossible to determine, just by looking, when air filters should be changed. An element that looks relatively clean may be almost totally plugged with ultra-fine particles from exhaust smoke or air pollutants.
Diesel Fuel Analysis
Colonies of fungus and bacteria, both aerobic and anaerobic, feed on your fuel. Commonly known as humbugs, they spread rapidly in the presence of moisture. They ride along with the fuel, easily pumped from one tank to another. As the micro-organisms accumulate, they will spread through the fuel system and quickly plug the fuel filter. A coating of slime will develop over the entire surface of the media. Chemical treatment with a biocide is the only effective solution to the problem of bacterial and fungal growth.
Contaminants arrive in your fuel in two forms - precipitates and particulates. Precipitates are non-combustible materials formed when fuel oxidizes. They may also form if, as sometimes happens, two incompatible fuels are blended. Significant swings in temperature accelerate the precipitation problem. Because precipitates are generally heavier than fuel, they tend to settle to the bottom of tanks. Decanting or carefully drawing off the fuel will leave the precipitates behind. Particulates, sometimes called "asphaltines," are black, tar-like contaminants. A residue of the refining process, particulates plug filters quickly. There is no known chemical treatment for the removal of these contaminants.
