Suppliers are required to assume all patent liability. 2016 by Navistar, Inc. JUNE 2016 Page 5 of 5 A.0 GENERAL INFORMATION (Not a Requirement) A.1 Type I material is a
41、 solvent borne general purpose corrosion inhibitor used to prevent corrosion of machined and unpainted parts during outdoor exposure. It is also used extensively to inhibit galvanic corrosion between steel and aluminum surfaces in contact. This type of material is specified in Parts Lists F100011133
42、 and R100011133. Type I material requires a one hour drying time. When shorter drying times are anticipated Type III material is used in place of Type I. A.2 Type II material is used for fasteners. It provides a torque-tension relationship similar to phosphated and oiled fasteners. The Type II mater
43、ial is used to inhibit galvanic corrosion between steel fasteners in contact with aluminum parts. Its use is also specified in Parts Lists F100011133 and R100011133. A.3 Type III material is a faster drying version of Type I and used in similar applications when the need for shorter drying times are
44、 anticipated. A.4 Types I, II and III materials are similar and substitution of one of these types for another is permissible. However, the using International facility is responsible to select product suitable for the intended application and to insure that all requirements of this specification ar
45、e satisfied. A.5 Type IV is a pigmented (black) corrosion inhibitor used as a primer on springs and other unpainted parts. Its use is specified on suspension springs in MPAPS A-1037 and MPAPS A-1044. A.6 Type V is a special surface corrosion inhibitor used in wheel assemblies. Its use is specified i
46、n Engineering Drawing WA00032698 as P/N 2644068R1. A.7 Type VI is a special adhesive tape product which may be coated with an anti-corrosion wax product or impregnated with a surface chemical to provide a dielectric barrier to prevent contact between the dissimilar metal surfaces.
