IO-360-P1A Engine Illustrated Parts CatalogIntroductionDO NOT USE THIS CATALOG AS AN ASSEMBLY OR INSTALLATIONDOCUMENT. THIS CATALOG MUST ONLY BE USED TO IDENTIFY PARTS INCONJUNCTION WITH THE APPLICABLE OVERHAUL MANUAL.Purpose of this CatalogThis Illustrated Parts Catalog (IPC) contains a complete list of spare parts for the Lycoming IO-360P1A engine model.How to Use this CatalogThis catalog is based on the Air Transport Association (ATA) Spec 100 format. In order to clarifyillustrations, Lycoming has taken discretion to classify non-system related assemblies andcomponents in the same chapters, because they are physically connected.This catalog is frequently updated by Service Bulletins (SB) and Service Instructions (SI). Theupdated information will be incorporated into subsequent full revisions of this catalog.The ATA two element numbering system provides consistency throughout various manuals. Thebottom of each page (beyond the frontal section) contains a two element number (##-##). In the twoelement numbering, the first two digits represent a chapter, and the next two digits subdivide thematerial into a more specific section.The ATA format specifies the subject matter for each chapter-section. According to the ATAStandards, the following chapters apply to the IO-360-N1A Illustrated Parts Catalog:24 (Electrical Power), 72 (Reciprocating Engine), 73 (Engine and Fuel Control), 74 (Ignition), and 80(Starting).EXAMPLE:74 — 20ChapterIgnitionNOTICE:SectionDistributionSee the IPC Table of Contents for the sub-systems identified in each section.Numerical IndexThe Numerical Index is a single list of part numbers, names and their locations within the IPC. It isuseful for locating parts when you only know the number or name of the part.Description columnIndentation of a part name represents a lower level of assembly. Attaching parts have the sameindentation level and are below their associated parts grouping or assembly. This column is oftenreferred to as the "Nomenclature" on other ATA Spec manuals.Units per Assembly ColumnWhere more than one assembly exists, this column contains the quantity of a specific part requiredin the build sequence of only one next higher assembly. The letters “AR” are for “as required”applicable to bulk items or non-illustrated select-from-range-parts. The letters “RF” identify itemslisted for reference.Effectivity: IO-360-P1A EngineCopyright, Lycoming EnginesLycoming Engines is a division of Avco CorporationIntroductionPage vJuly 2017
IO-360-P1A Engine Illustrated Parts CatalogRoller TappetsAs a product improvement, Lycoming is installing roller tappets on its aircraft engines. Wide deckengines with roller tappets are identified with an “E” suffix after the serial number dash number(Example – L-******-48E.) On rebuilt and Lycoming overhauled wide deck engines with rollertappets, the letter “A” suffix is replaced with the letter “E” suffix on the engine serial number.The new parts include roller tappet body assembly, crankcase, camshaft, shorter push rods, shroudtubes and shroud tube seal. The engines use the same hydraulic units and the dry tappet clearancedoes not change. Refer to Reference 618 in the Table of Limits (SSP-1776) for dry tappet clearancevalues.At this time, roller tappets are not installed in narrow deck engines.ROLLER TAPPET PARTS ARE NOT INTERCHANGEABLE WITH CURRENT FLAT FACEDTAPPETS.If it is necessary to remove the roller tappet bodies prior to overhaul, they must be reinstalled inthe same location in the crankcase. The roller tappets are indexed with flats in the newcrankcase. It is possible to assemble the roller tappet bodies in two different orientations 180degrees apart. Either orientation is acceptable while reinstalling. Lubricate all tappet bores, camlobes and roller tappets with engine oil mixture only. (Refer to the latest revision of ServiceInstruction No. 1059.) Install the shroud tube seal in the crankcase, then install the shroud tube.THE ROLLER TAPPETS ARE NOT FIELD REPAIRABLE AND NO DISASSEMBLY ISALLOWED. THEREFORE, MAGNAFLUX OR ZYGLO INSPECTIONS ARE NOT ALLOWED. AVISUAL INSPECTION FOR INTEGRITY AND FREE ROTATION OF THE ROLLER ACTION ISACCEPTABLE TO RETURN AN IN-USE ROLLER TAPPET TO SERVICE; HOWEVER, IT ISMANDATORY TO REPLACE ROLLER TAPPETS AT OVERHAUL.Vendor AccessoriesParts coverage of Vendor Accessories used on Lycoming engines are found in the applicableVendor’s Parts Catalog. A list of vendors’ addresses is included in the latest revision of LycomingService Letter No. L114.Any reference in this document to the supplier’s/part manufacturer’s product, by name, trademark,part number or other description is solely for the purpose of identification and does not indicate orinfer that Lycoming accepts responsibility for quality control and/or airworthiness of parts, which donot pass through the Lycoming quality control system.Environmental ComplianceLycoming is concerned with preserving the environment. Lycoming strongly urges engine ownersand repair/overhaul personnel to observe and comply with all federal, state, and local environmentalregulations when solvents, paint, fuel, oil, chemicals, or other consumables are used in operating,maintaining, or overhauling an engine component. Please share our concern for, and commitmentto a clean earth, clean water, and especially clean air for succeeding generations of flyers.IntroductionPage viJuly 2017Effectivity: IO-360-P1A EngineCopyright, Lycoming EnginesLycoming Engines is a division of Avco Corporation
