{"title":"Lycoming","description":"\u003cp\u003eLycoming, the American aircraft-engine manufacturer of Williamsport, Pennsylvania, builds the air-cooled flat engines that power a large share of the world's general-aviation fleet. This page offers workshop, service, overhaul and parts manuals for Lycoming aircraft engines, from small four-cylinder trainers to large turbocharged sixes.\u003c\/p\u003e\u003c!--more--\u003e\u003cp\u003eThe Lycoming name comes from Williamsport, Pennsylvania, where an industrial works that traced its origins to the nineteenth century began building engines in the early 1900s. The company later produced automobile engines as well, but it is best known today as one of the two great American makers of piston aircraft engines, now part of the Textron group.\u003c\/p\u003e\u003cp\u003eLycoming engines are air-cooled, horizontally opposed four-, six- and eight-cylinder designs such as the O-320, O-360, IO-540 and their turbocharged variants. They power hundreds of thousands of aircraft, from trainers and light singles to twins, and are prized for predictable maintenance and a vast installed base supported by parts and documentation worldwide. The models documented in this collection cover much of today's trainer and light-aircraft fleet.\u003c\/p\u003e\u003cp\u003eThe manuals on this page provide factory-level documentation for Lycoming engines, including cylinder and valve service, crankshaft and bearing overhaul, fuel and induction systems, lubrication, ignition and electrical systems, torque specifications and inspection procedures. Overhaul and parts-catalog listings support both major work and routine scheduled maintenance. Because engine life is measured in operating hours rather than miles, the inspection limits and overhaul data in these manuals are especially important.\u003c\/p\u003e\u003cp\u003eThese documents are intended for aircraft owners, flight schools, aviation maintenance technicians and engine-overhaul shops. Following the manufacturer's procedures and specifications is essential to safety, reliability and the continued airworthiness of these engines.\u003c\/p\u003e","products":[{"product_id":"lycoming-to-360-lto-360-series-engine-parts-catalog","title":"LYCOMING TO-360 \u0026 LTO-360 Series Aircraft Engines Parts Catalog Manual-","description":null,"brand":"Lycoming","offers":[{"title":"Default Title","offer_id":44022698148020,"sku":"209760","price":16.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/4746\/1044\/files\/209760-lycoming-to-360-and-lto-360-series-aircraft-engines-parts-catalog-manual-download-pdf.jpg?v=1756360969"},{"product_id":"lycoming-o-235c-and-o-290d-overhaul-manual-pdf","title":"Lycoming O 235C and O 290D Overhaul Manual PDF","description":"\u003cdiv style=\"font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,Helvetica,Arial,sans-serif;line-height:1.65;color:#1f2933;\"\u003e\n  \u003cdiv style=\"background:linear-gradient(135deg,#172033,#26364f);color:#fff;border-radius:14px;padding:26px 24px;margin-bottom:18px;\"\u003e\n    \u003cdiv style=\"font-size:12px;letter-spacing:.12em;text-transform:uppercase;font-weight:700;color:#d7e6ff;margin-bottom:9px;\"\u003eLycoming · Piper · Service Repair Manual\u003c\/div\u003e\n    \u003ch2 style=\"margin:0 0 10px;font-size:27px;line-height:1.2;color:#fff;\"\u003eLycoming O 235C and O 290D Overhaul Manual PDF\u003c\/h2\u003e\n    \u003cp style=\"margin:0;font-size:15px;color:#eef3fb;max-width:760px;\"\u003eDownloadable workshop manual with repair, maintenance and troubleshooting information for owners, technicians and restoration work.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv style=\"display:grid;grid-template-columns:repeat(auto-fit,minmax(160px,1fr));gap:10px;margin-bottom:20px;\"\u003e\n    \u003cdiv style=\"background:#f8fafc;border:1px solid #e2e8f0;border-radius:10px;padding:13px 15px;\"\u003e\n\u003cstrong\u003eFormat\u003c\/strong\u003e\u003cbr\u003eDigital PDF Manual\u003c\/div\u003e\n    \u003cdiv style=\"background:#f8fafc;border:1px solid #e2e8f0;border-radius:10px;padding:13px 15px;\"\u003e\n\u003cstrong\u003eMake\u003c\/strong\u003e\u003cbr\u003eLycoming\u003c\/div\u003e\n    \u003cdiv style=\"background:#f8fafc;border:1px solid #e2e8f0;border-radius:10px;padding:13px 15px;\"\u003e\n\u003cstrong\u003eModel\u003c\/strong\u003e\u003cbr\u003e300 Series\u003c\/div\u003e\n    \u003cdiv style=\"background:#f8fafc;border:1px solid #e2e8f0;border-radius:10px;padding:13px 15px;\"\u003e\n\u003cstrong\u003eAccess\u003c\/strong\u003e\u003cbr\u003eInstant Download\u003c\/div\u003e\n  \u003c\/div\u003e\n  \u003ch3 style=\"font-size:20px;margin:24px 0 12px;border-bottom:2px solid #e2e8f0;padding-bottom:8px;\"\u003eAbout this manual\u003c\/h3\u003e\n  \u003cp\u003eLycoming O 235C 290D Service Repair Workshop Manual VEHICLE INTRODUCTION: This professional service repair manual provides comprehensive coverage for the premium.
