Introduction
This instruction gives the recommended procedure for replacing the folded core modules of the folded core radiator with multiple row modules.In some applications, dust, fibrous or fluffy debris can cause air side plugging of the folded core modules. This can result in increased maintenance intervals.The multiple row modules have a lower fin density of approximately 3.5 fins/cm (9fins/in) versus approximately 13 fins/cm (33 fins/in) on the folded core module. The lower fin density of the multiple row modules are more open to air flow through the core, making it more resistant to plugging by fine, fibrous or fluffy debris. The use of multiple row modules will improve resistance to debris plugging on the air side of the radiator.However, unlike the folded core module, the multiple row modules have no locating pins on the end tanks to correctly position the modules. Therefore the locating depressions (dimples) in the radiator bottom tank are used.This procedure applies to all vehicular engine applications that currently have multiple row modules available for conversion, However, no modules or procedures are available at this time for Off-Highway Trucks and Tractors.Do not perform any procedure, outlined in this publication, or order any parts until you read and understand the information contained within.Reference: Service Manual, Parts Manual, Operation and Maintenance Manual.Installation Procedure\Applicable Models: All vehicles except 627E, 637E, and 657 Scrapers
Correct location of the module is required because of the unequal spacing between adjacent module openings in the end tanks.
(A) Typical hole spacing in the top and bottom tanks. (B) Air flow. (C) Trash gap. (D) Folded core modules. (E) Smaller spacing. (F) Larger spacing.The unequal spacing exists because of the folded core "trash gaps".The diagonal cut (notch) on the stiffener tab and the two ribs in the end tanks represent the wide spacing for the trash gaps.
Location of the two ribs and typical dimple locations. (G) 2 small ribs. (H) Center stiffener notch. (J) Former trash gap.Dimples (solid dots) are shown for illustration purposes only. Also notice that the location of the dimples are staggered.Positioning the modules may be confusing because some modules have a trash gap formed by the first and second folded core modules while other models form the trash gap with the second and third modules.
Position of multiple row modules in D4H Tractors, 916, 926 Loaders and IT 18, IT28 Toolcarriers. (H) Center stiffener notch. (J) Former trash gap.Trash gaps located between the second and third, fourth and fifth module. Typical dimple locations (solid dots). Dimples shown above for illustration purposes only. Also notice that the location of the dimples are staggered.This means that regardless of the position of the first module, the multiple row modules should have the "narrow" sides toward each other and the wide sides toward each other.
End view of multiple row module. (G) Embossed ribs on end tanks. (H) Center Stiffener Notch. (L) End view of multiple row module. (M) Neck.Dimensions for positioning the module with the "narrow" side toward each other, and the "wide" sides toward each other,
