GASKET TANK TO CORE 4N5572 - Caterpillar

Hoses and clamps must be inspected periodically in order to ensure safe operation and continuous operation of the engine. Take proper safety precautions before inspecting or replacing hoses and clamps.Note: Always use a board or cardboard when the engine components are checked for leaks. Leaking fluid that is under pressure can cause serious injury or possible death. Leaks that are the size of a pin hole are included. Refer to Operation and Maintenance Manual, "General Hazard Information" for more information.Inspect the Hoses and the Clamps
Inspect all hoses for leaks that are caused by the following conditions. Replace any hose which exhibits any of the following conditions. Failure to replace a hose which exhibits any of the following conditions may result in a hazardous situation.
Hoses which are cracked
Hoses which are soft
Outer covering that is chafed or cut
Exposed wire that is used for reinforcement
Outer covering that is ballooning locally
Flexible part of the hose that is kinked or crushed
Armoring that is embedded in the outer covering
Hoses which exhibit signs of leakage which are not the result of loose couplings or clampsInspect all clamps for the following conditions. Replace any clamp which exhibits signs of any of the following conditions.
Cracking
Looseness
DamageInspect all couplings for leaks. Replace any coupling which exhibits signs of leaks.Each installation application can be different. The differences depend on the following factors:
Type of hose
Type of fitting material
Anticipated expansion and contraction of the hose
Anticipated expansion and contraction of the fittingsDue to extreme temperature changes, the hose will heat set. Heat setting causes hose clamps to loosen which can result in leaks. A constant torque hose clamp will help to prevent loose hose clamps.Replace hoses that are cracked or soft. Replace hoses that show signs of leakage. Replace hoses that show signs of damage. Replace hose clamps that are cracked or damaged. Tighten or replace hose clamps which are loose.
