3 LYCOMING MODEL 0-30 SERIES AIRCRAFT ENGINES INTRODUCTION The parts lists and Illustrations in this catalog provide an easy method of identification, for procurement and servicing purposes, of any part used on Lycoming Model 0-30 Series Aircraft Engines. The catalog contains six sections which are described in the following paragraphs. THE ILLUSTRATED PARTS SECTION consists of explodedviews of thebasic 0-30 Series engines. These views illustrate all procurable parts which are indicated and identified by part number. THE NUMERICAL PARTS SECTION contains the part number of allprocurable partsused on these engines and are arranged in numerical sequence. Following each part listing a complete dimensional description is given. along with the quantity required for each engine. If the part is anassembly the quantity, part number andname of its components are given. Certain components of these assemblies may be prefixed by an (*) which indicatesthat the detail part cannot be procured as such but can be obtained only by ordering the next higher assembly of which it is a component. THE NUMERICAL STANDARDS PARTS SECTION is similar to the NumericalParts Section excepting only that the part numbers are prefixed by the symbol "STD". This symbol indicates that the part is a Lycoming standard part and is not necessarily peculiar to these engines. The standard parts include such items as nuts, bolts, washers, and seals. THE OVERSIZE AND UNDERSIZE PARTS SECTION consists of a list of such parts that are available in sizes other than nominal or standard. This list states the part name or number of the part and the non standard sizes in which it may be procured. THE SERVICE REPLACEMENT SET SECTION consists of a list of service replacement sets such as seals, gaskets or complete cylinder, piston and ring combinations. The individual items in these sets are listed separately in the Numerical Section of the catalog and may be individually procured. THE ATTACHING PARTS SECTION consists of a complete listing of all assemblies and subassemblies contained in the engine, along with their attaching parts. These assemblies and subassemblies are arranged in an alphabetical sequence and immediately beneath each listing are shown the parts that are required to attach each assembly. The quantity shown under the "No. Required" column are for one assembly only. INSTRUCTIONS FOR ORDERING PARTS Always, when ordering parts, state the part number, its correct name, and quantity desired. In addition state the complete model and serial number of the engine. This information will be found on the Name Plate which is attached to the sump. Unless credit has been established with Textron Lycoming, all parts will be shipped C.O.D. or with sight draft attached to bill of lading on freight shipment. WHEN ORDERING PARTS BE CERTAIN TO INCLUDE ENGINE MODEL AND SERIAL NUMBER. iii
