Proper protection of the components from corrosion is important. Corrosion will start in as little as one hour after the components have been cleaned.When the components will not be inspected for one hour or less the components should be coated with a rust or corrosion inhibitor or coated with clean engine oil. The components should be individually wrapped to prevent contamination, and should be stored in a protected area to avoid damage. See Illustration 43.When the components will not be inspected in two days or more the components should be coated with a rust or corrosion inhibitor or coated with clean engine oil and should be placed in a container which is clean and structurally solid. The container should be covered or wrapped in plastic to prevent damage and contamination to the components. See Illustration 44.Refer to SEHS9031Special Instruction, "Storage Procedure for Caterpillar Products" for more information.
