The generator set manufacturerreserves the right to change this publication and theproducts represented without notice and without anyobligation or liability manual includes the following main sections: Table of the sections of the (and other information sections).Contains introductory material about part numbers,illustrations, and the engine models and Parts the part numbers of parts in System SignificanceThis manual uses the following numbering systems:Engine product identification numberlocated on the engine nameplate. Engines break downinto unique number representing a partsgroup needed to assemble an engine function.

For example, a 12-voltalternator and 24-volt alternator both perform the samefunction, but, with different parts. Each differencerequires a group variation or module part number identifies an individualassembly, subassembly, component, or accessory (or exploded-view drawings) bestrepresenting the widest range of variations accompanymostgroupsinthismanual.

4 Theheadings identify the groups of parts that make upthe the groupmost likely to include theservice part the group variation numberat theintersection of the model row and the groupcolumn. Note the variation number. If 2 or morevariation numbers are listed, note all forward to locate the groupidentified instep 3 or find the appropriate page in the Table the part on the illustrationand note the itemnumber of the part orfind the part description inthe parts Selectthe part number that corresponds toyour group variation. The first column lists theillustration item number. Find the variation(s)identified in the Specification Number Index in theappropriate column on the right side ofthe partslisttable.

5 Find the quantity used at the intersection ofthe item number row and the variation column. Ablank space at the intersection means thevariation/module does not use that part ReferencesMany common hardware items do not appear in partsmanuals or will appear as common hardware entries. Acommon hardware entry lists the size of the example, an item that appears as Hardware,3/8-16 in the text means that the piece is 3/8-16 common hardware hardware items require a specific size or someother characteristic. In that case, use the part replacing hardware, do not substitute equal to or better than the grade of themanufacturer s original 3/14 Model Number Index, Engine Model 4024/5030 Group 10 11 12 13 14 Variation NumberGroup Title20/30 REOZJC (Specification Numbers GM57153-GAxx)4024TF28117032001 220124062301B860387012999460449071101B16 3220/30 REOZJC (Specification Numbers GM73381-GAxx)4024TF28117032001 220124132304860487012999460449071101B163 240/50 REOZJC (Specification Numbers GM57153-GAxx)4024HF285 2001 2201243523098603870129994618490711091662 40/50 REOZJC (Specification Numbers GM73381-GAxx)
