SUPPLEMENTAL PARTS LIST

To Provide Parts Coverage for ModelO-320-E2G Lycoming Aircraft Engines

This supplemental parts list is written to provide an engine partscomparison between the O-320-E2D as listed in Lycoming PC-103, andengine model O-320-E2G. It is written to follow PC-103 page by page andpart by part. Figure reference numbers, part numbers and page numbersfollow exact construction of PC-103. Where necessary, because of numer-ous changes, all parts applicable to O-320-E2G model engines are listed.

If a part number in this supplement does not have a figure referencenumber, it denotes a new part, or a part not figure referenced in PC-103,or parts that are peculiar to O-320-E2G model engines. If a page inPC-103 is not applicable to O-320-E2G model engines, it is so designatedin this supplement.

NOTICE

The spark plugs listed herein, are those used in currentproduction only; this listing does not include additionalspark plugs that are approved for use in these engines.See latest edition of Service Instruction No. 1042 forcomplete listing of all spark plugs.

SUPPLEMENTAL PARTS LIST SSP2872

TO PROVIDE PARTS COVERAGE FOR LYCOMINGMODEL 0-320-D1F and 0-320-E1F ENGINES

This parts supplement is not arranged in the same format as PC-103, but it

is based on the same page and reference numbers listed in PC-103.

The departure appears when 0-320-D1F or ElF engine parts are referred to

under a particular column on the original catalog page. Parts listed under that

column are the same on both D1F and ElF engines unless otherwise specified.

Example: Parts onpage 1-7 under column 0-320-E2C are the same as onboth

0-320-D1F and 0-320-ElF engines.

Only those parts which are different, new, or require a different quantity

than in PC-103 are listed. Pages in the original parts catalog which do not apply

to 0-320-D1F or 0-320-EIF engines are so designated.

SUPPLEMENTAL PARTS LIST NO. SSP2771

To provide parts coverage for Lycoming

IO-320- DB MODEL ENGINES.

This parts supplement is not necessarily arranged in the same basic

format as the original publication PC-103. 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-320-D1B engine

parts are referred to a particular column on the basic catalog page.

For example: The piston assembly for IO-320- DB model engines may

be referred to as under column headed by IO-320-DIA. This means

that allparts listedunder this heading also apply toIO-320-D1B 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-103,

not applicable to the IO-320-D1B model engine, will be so designated

in this supplement.

INTRODUCTION

1. GENERAL.

This illustrated parts catalog lists and describes all procurable parts for the Lycoming engines listedherein.

2. SUPERSEDURE SECTION.

This section lists part numbers in numerical sequence, first by superseded number to the new, or supersedingpart number. The second portion of this section lists the superseding, or new part number to the old or supersedednumber.

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 listedin the order of engine assembly at the factory. Illustrations are on the page directly opposite or beneath the partdescription.

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. Sub-columns are employed here to differentiate parts of assemblies or sub-assemblies. Notes appearing in the textshould be checked prior to ordering parts. All references to Lycoming Service Bulletins, Instructions andLetters should be fully observed. The letters (STD) appearing beside the part description means this part fits anengine manufactured with the Standard cylinder base flange. The letters (WCF) means this part fits an enginemanufactured with the wide cylinder base flange. When neither appears in the description column, the part is ap-plicable to either configuration.

The "Quantity Per Assembly" portion of the text page indicates by model number the quantity required to com-plete the assembly on that page.

4. SERVICE REPLACEMENT SET SECTION.

This section consists of the seal and gasket set applicable to the 0-320 series engine. Individual parts con-tained in kits are also listed in the group assembly parts list and may be procured separately.

5. VENDOR ITEMS SECTION.

This section consists of assemblies produced by manufacturers other than Lycoming, for use onLycoming engines. Numbers in "Part Number" column are those of the particular vendor. Parts for these assem-blies can be obtained by ordering from Lycoming, Williamsport, Pa.

6. NUMERICAL INDEX.

This section lists all part numbers contained in the group assembly parts list (Sections 1 thru 7), in alpha-numerical sequence. Column headings are self-explanatory.

7. INSTRUCTIONS FOR ORDERING PARTS.

Use of this catalog is keyed to engine model number. The model number can best be determined by visual in-spection of the name plate located on the oil sump. Series of engines identified by the letter "A" following theserial number suffix are manufactured with the wide cylinder base flange. Example: 0-320-A, Serial NumberL- 12093- 39A.

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.
