SEAL 4323246 - Caterpillar

Lubricate all points mentioned in the lubrication chart if the engine is to be stored or left standing for any length of time. This will protect against rusting.If the engine is to be stored or left standing for a long period of time, the lubricating oil may drain away from the cylinder walls and piston rings. This lack of lubricant permits the rings and liners to rust. It also permits unnecessary wear caused by metal-to-metal contact between the pistons, rings and liners when the engine is started before fresh oil has reached these surfaces. The lack of lubricant may not cause any noticeable change in engine operation after it has been started, but it does contribute to shorter engine life.The oil film should be renewed by running the engine once a week until it is thoroughly warm. This will circulate the oil and prevent rusting from condensation. COOLING SYSTEM: If temperature is expected to be below freezing, completely drain the cooling system or add sufficient antifreeze to give proper protection. BATTERY: Test the battery periodically and recharge if necessary. FUEL TANK: If the truck is to be stored or left standing longer than the normal work day, fill the tank with clean fuel to drive out moisture laden air. This will prevent condensation and rust from forming inside the tank. If the truck is to be stored with the fuel tank empty or partially filled, commercially available rust preventative Vapor Phase Inhibitor Crystals should be placed in a cloth bag and hung inside the tank filler opening to prevent moisture and rust from collecting. Crystals should not be dropped into the fuel as they will not function when saturated with fuel. Remove the crystals before the fuel tank is to be refilled with fuel.
