2 INTRODUCTION The Avco Lycoming 76 series and LO-360 model engines depicted herein employ a modern unitized design crankcase. This incorporates all accessory drives in the crankcase eliminating a separate accessory housing and providing a compact, lightweight power unit. The parts catalog is constructed in the same familiar format as previous catalogs, the only difference being that the accessory drives section is now integrated with the Crankcase Group in Section 1. An oversize and undersize parts list shows available parts and their sizes. A Numerical Index is provided for convenience in finding parts when only the part number is known. Complete coverage of Vendor Accessories used on Avco Lycoming engines may be secured by referring to the publications listed in footnotes in this catalog on the page where the accessories are installed. A complete list of Vendor publications may also be found by referral to Service Letter No. L114. NOTE The illustrations, pictures and drawings shoun in this publication, are typical of the subject matter they portray; in no instance me they to be interpreted as examples of any specific engine, equipment or part thereof. SERVICE BULLETINS, INSTRUCTIONS AND LETTERS Although the information contained in this parts catalog is up-to-date at time of publication, users are urged to keep abreast of later information through Avco Lycoming Service Bulletins, Instructions and Service Letters which are available through all Avco Lycoming Distributors or from the factory by subscription. Consult the latest edition of Service Letter No. L114 for subscription information.
