CAMSHAFT 10R3325 - Caterpillar

Cooling
Never add coolant to an overheated engine, allow engine to cool first.Measure specific gravity of antifreeze solution frequently in cold weather to assure adequate protection.When permanent antifreeze and water solutions are used in the cooling system, the solution should be drained and replaced EVERY 2000 SERVICE HOURS OR 1 YEAR.When additions of corrosion inhibitor are made to the cooling system EVERY 500 SERVICE HOURS OR 3 MONTHS, it is not necessary to drain and refill yearly. Cooling system drain period can then be extended to 4000 service hours or 2 years.Maintain a 3% concentration of Caterpillar Cooling System Inhibitor, or equivalent, in the cooling system regardless of antifreeze concentration.Do not use Caterpillar Cooling System Inhibitor with Dowtherm 209 coolant.If a machine is to be stored in, or shipped to an area with below freezing temperatures, the cooling system must be protected to the lowest expected ambient temperature or drained completely.
The engine cooling system is protected to -20°F (-29°C), with permanent-type antifreeze, when shipped from the factory. Pure undiluted antifreeze will freeze at -10°F (-23°C).Use clean water that is low in scale forming minerals, not softened water. Add Caterpillar Cooling System Inhibitor, or equivalent, to the water to provide corrosion protection. Follow the recommendations on the container for the quantity required.Whenever draining and refilling cooling system, always measure the coolant level when the engine reaches normal operating temperature.Filling at over 5 gpm (19 litres/min) rate can cause air pockets in the cooling system.When measuring the coolant level, inspect the filler cap gasket. Replace gasket if it is damaged.Premix antifreeze solution to provide protection to the lowest expected ambient temperature.Operate with a thermostat in the cooling system all year round. Cooling system problems can arise without a thermostat.Fuel
Fill fuel tank at the end of each day of operation to drive out moisture laden air and to prevent condensation. Do not fill the tank to the brim. The fuel expands when it gets warm and may overflow.
Water and sediment should be drained from the tank at the start of each shift or after the fuel tank has been filled and allowed to stand for 5 to 10 minutes.If engine fuel system is equipped with a water separator, drain water from water separator daily before starting the engine. Always drain water from separator before it becomes one-half full. Frequent draining may be necessary in areas of high humidity or when the fuel supply is contaminated with water.Drain water and sediment from the main fuel storage tank weekly, and before the tank is refilled. This will help prevent water or sediment from being pumped from the storage tank into the machine fuel tank.Measure fuel level with dipstick in filler opening.After changing fuel filter, always bleed fuel system to remove air bubbles from the system.Air Intake
Inspect air intake precleaner daily for accumulation of dust and debris.Service air cleaners when RED band in indicator locks in visible position.Electrical
When using external electrical source to start machines with direct electric starting, turn disconnect switch off and remove
