Cleanliness of the Engine
It is important to maintain extreme cleanliness when working on the fuel system, since even tiny particles can cause engine or fuel system problems.
The entire engine should be washed with a high pressure water system in order to remove dirt and loose debris before starting a repair on the fuel system. Ensure that no high pressure water is directed at the seals of the injectors.Environment
When possible, the service area should be positively pressurized in order to ensure that the components are not exposed to contamination from airborne dirt and debris. When a component is removed from the system, the exposed fuel connections must be closed off immediately with suitable sealing plugs. The sealing plugs should only be removed when the component is reconnected. The sealing plugs must not be reused. Dispose of the sealing plugs immediately after use. Contact your nearest Caterpillar dealer or your nearest approved Caterpillar distributor in order to obtain the correct sealing plugs.New Components
High pressure lines are not reusable. New high pressure lines are manufactured for installation in one position only. When a high pressure line is replaced, do not bend or distort the new line. Internal damage to the pipe may cause metallic particles to be introduced to the fuel.All new fuel filters, high pressure lines, tube assemblies and components are supplied with sealing plugs. These sealing plugs should only be removed in order to install the new part. If the new component is not supplied with sealing plugs then the component should not be used. The technician must wear suitable rubber gloves. The rubber gloves should be disposed of immediately after completion of the repair in order to prevent contamination of the system.Refueling
In order to refuel the diesel fuel tank, the refueling pump and the fuel tank cap assembly must be clean and free from dirt and debris. Refueling should take place only when the ambient conditions are free from dust, wind and rain. Only use fuel, free from contamination, that conforms to the specifications in the Operation and Maintenance Manual, "Fluid Recommendations" Fuel Specifications.
