4 SUPPLEMENTAL PARTS LIST To Provide Parts Coverage for Model O-30-EG Lycoming Aircraft Engines This supplemental parts list is written to provide an engine parts comparison between the O-30-ED as listed in Lycoming PC-03, and engine model O-30-EG. It is written to follow PC-03 page by page and part by part. Figure reference numbers, part numbers and page numbers follow exact construction of PC-03. Where necessary, because of numerous changes, all parts applicable to O-30-EG model engines are listed. If a part number in this supplement does not have a figure reference number, it denotes a new part, or a part not figure referenced in PC-03, or parts that are peculiar to O-30-EG model engines. If a page in PC-03 is not applicable to O-30-EG model engines, it is so designated in this supplement. NOTICE The spark plugs listed herein, are those used in current production only; this listing does not include additional spark plugs that are approved for use in these engines. See latest edition of Service Instruction No. 0 for complete listing of all spark plugs. SSP76 February, 976

Page numbers here correspond to page numbers in PC-03. Reference numbers here correspond to reference numbers in PC-03. Where reference numbers listed in PC-03 are not used in this parts list it indicates those references are not applicable to O- 30- E3D engines. Where parts are listed in this parts list without reference numbers it indicates those parts are not illustrated in PC-03. Use all parts, but only those parts listed in this parts list for model - 30-E3D engines. Where the notation "use column 0-30-ED" for a particular page appears (eg.: Page -7), all parts applicable to 0-30-ED engines also apply to 0-30-E3D engines.

40 SUPPLEMENTAL PARTS LIST NO. SSP77 To provide parts coverage for Lycoming IO-30- DB MODEL ENGINES. This parts supplement is not necessarily arranged in the same basic format as the original publication PC-03. However, it is arranged to provide parts coverage by using the same page as listed in the basic catalog. The departure, therefore, appears when IO-30-DB engine parts are referred to a particular column on the basic catalog page. For example: The piston assembly for IO-30- DB model engines may be referred to as under column headed by IO-30-DIA. This means that allparts listedunder this heading also apply toio-30-db model engines and the only listings present in the supplement will be those parts that are different, new or parts that require a different quantity per engine assembly. Any pages listed in the basic catalog, PC-03, not applicable to the IO-30-DB model engine, will be so designated in this supplement. SSP 77 PC-03 November, 97

50 LYCOMING AIRCRAFT ENGINE GROUP ASSEMBLY PARTS LIST 0-30, IO-30, LIO-30 SERIES INTRODUCTION. GENERAL. This illustrated parts catalog lists herein. and describes all procurable parts for the Lycoming engines listed. SUPERSEDURE SECTION. This section lists part numbers in numerical sequence, first by superseded number to the new, or superseding part number. The second portion of this section lists the superseding, or new part number to the old or superseded number. 3. GROUP ASSEMBLY PARTS LISTS. This catalog is laid out in graph format indicating engine model number on each text page. The sections of this catalog divide the engine into various assemblies and related parts. These parts are listed in the order of engine assembly at the factory. Illustrations are on the page directly opposite or beneath the part description. The "Figure Reference Number" column (with heading "REF") provides cross reference to the part illustration. Those parts not numbered in this column are not illustrated. The "Part Number" column contains the Lycoming, AN, MS, or vendor part number. The "Description" column provides description or dimensional information required to describe the part. Subcolumns are employed here to differentiate parts of assemblies or sub-assemblies. Notes appearing in the text should be checked prior to ordering parts. All references to Lycoming Service Bulletins, Instructions and Letters should be fully observed. The letters (STD) appearing beside the part description means this part fits an engine manufactured with the Standard cylinder base flange. The letters (WCF) means this part fits an engine manufactured with the wide cylinder base flange. When neither appears in the description column, the part is applicable to either configuration. The "Quantity Per Assembly" portion of the text page indicates by model number the quantity required to complete the assembly on that page.. SERVICE REPLACEMENT SET SECTION. This section consists of the seal and gasket set applicable to the 0-30 series engine. Individual tained in kits are also listed in the group assembly parts list and may be procured separately. parts con- 5. VENDOR ITEMS SECTION. This section consists of assemblies produced by manufacturers other than Lycoming, for use on Lycoming engines. Numbers in "Part Number" column are those of the particular vendor. Parts for these assemblies can be obtained by ordering from Lycoming, Williamsport, Pa. 6. NUMERICAL INDEX. This section lists all part numbers contained in the group assembly numerical sequence. Column headings are self-explanatory. parts list (Sections thru 7), in alpha- 7. INSTRUCTIONS FOR ORDERING PARTS. Use of this catalog is keyed to engine model number. The model number can best be determined by visual inspection of the name plate located on the oil sump. Series of engines identified by the letter "A" following the serial number suffix are manufactured with the wide cylinder base flange. Example: 0-30-A, Serial Number L A. After engine model number and type cylinder flange is determined, look in the Table of Contents for the part, or for the assembly on which it would normally be found. If the part number is known, look in the numerical index (Section 0) in the back of the catalog. The illustrations can also be used to aid in finding the part.. OPTIONAL ITEMS. Those optional items, such as electrical system components, vacuum and hydraulic dual drives etc., are catalogued by engine model number as the engine was assembled at the factory. See appropriate Service Instructions for further information. Use the illustrations to aid in determining the option you desire. i
