INTRODUCTION

The Avco Lycoming 76 series 0-360 and LO-360 model engines depicted herein employ a modemunitized design crankcase. This incorporates all accessory drives in the crankcase eliminating a separateaccessory housing and providing a compact, lightweight power unit.

The parts catalog is constructed in the same familiar format as previous catalogs, the only differencebeing 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 referringto the publications listed in footnotes in this catalog on the page where the accessories are installed. Acomplete list of Vendor publications may also be found by referral to Service Letter No. L114.

NOTE

The illustrations, pictures and drawings shown in this publication, are typical of the subject matter theyportray; in no instance are they to be interpreted as examples of any specific engine, equipment or partthereof.
