Lycoming Aircraft EnginesParts Catalog

INTRODUCTION

NOTE

This Parts Catalog supersedes PC-102 dated August, 1973 and PC-202 dated March, 1978.

This illustrated parts catalog contains a complete parts listing for the Lycoming 0-235series aircraft engines. For use in expediting of parts when ordering, the serial number and modeldesignation are stamped on the engine nameplate located on the oil sump.

The Group Assembly Section lists major assemblies and sub-assemblies in general sequence ofengine build-up. The "Quantity Per Assembly" column indicates the number required at thatparticular location only and is not to be construed to mean quantity for the complete engine.When the symbol "un" is listed, it means to use quanitity as necessary.

The Service Kit Section provides listings for seal and gasket sets and cylinder, piston and ringassemblies for use in ordering parts as necessary during overhaul.

The Numerical Index is provided for convenience in finding parts when only the part number isknown.

In the Oversize and Undersize Parts section, procurable oversize and undersize parts are listedpreceding the main group assembly parts list.

Parts coverage of Vendor Accessories used on Lycoming engines may be found in the ap-propriate Vendor's Parts Catalog. A list of the publications appear in the latest edition ofLycoming Service Letter No. L114.
