5 INTRODUCTION This illustrated Parts Catalog provides parts coverage for all current models of the IO, AIO, LIO and AEIO-30 wide cylinder flange (WCF) series engines. These wide cylinder flange engines are identified by the suffix letter "A" on the engine serial number (e. g. L A). The serial number as well as the model designation may be found on the engine nameplate located on the oil sump. It is this model designation by which parts application is governed throughout the parts catalog. Group Assembly Section: engine build-up. This section lists major assemblies and sub-assemblies in the general order of Service Kit Section: Seal and gasket sets and cylinder, piston and ring kit are provided in this section. Supersedure Section: This section lists a history of part numbers that have been superseded and gives a brief description of the change involved. Numerical Index: Quick determination of part location in the catalog is possible thru this section when only the part number is known. Vendor Accessories: Complete part breakdown vendor part in the catalog. of vendor parts using vendor numbers follows each Oversize and Undersize Parts List: Procurable oversize and undersize parts are listed preceding the main group assembly parts list. SERVICE BULLETINS, INSTRUCTIONS AND LETTERS Although the information in this catalog is up-to-date at the time of publication, users are urged to keep abreast of later information through Avco Lycoming Service Bulletins, Instructions and Letters which are available from all Avco Lycoming distributors or from the factory by subscription. Consult the latest edition of Service Letter No. L for subscription information. NOTE The illustrations, pictures and drawings shown in this publication are typical of the subject matter they portray; in no instance are they to be interpreted as examples of any specific engine, equipment or part thereof. IMPOR TANT NOTE Coverage for the AEIO-30-EIB and -EB models is provided within this catalog. These models use the same parts as their comparable 0-30-EB and -EB models except for differences in the accessory housing, oil sump and inverted oil systems which are listed herein. Parts required other than those special areas mentioned are found under the appropriate 0-30-EIB or -EB column. i
