• Chapter 2 — Engine Description: engine model number definition, cylinder numbering, crankcase, drive train, crankshaft, connecting rods, camshaft, cylinders, pistons, hydraulic tappets, lubrication system, engine cooling, induction and exhaust systems, and the Table 2-2 through Table 2-9 engine specification tables
• Chapter 3 — Special Tools and Supplies
• Chapter 4 — Airworthiness Limitations
• Chapter 5 — Engine Removal and Installation: aircraft and engine preparation, installation sequence, fuel injection system purge, preflight and run-up, and IO-550-A/B/C/G/N/P/R installation drawings
• Chapter 6 — Engine Inspection and Service: scheduled inspection items, induction/cylinder drain inspection, exhaust system inspection, Hartzell (Kelly) alternator inspection, unscheduled maintenance (propeller strike, hydraulic lock, overspeed, lightning strike, contaminated fuel, foreign object contamination), inspection checklists
• Chapter 7 — Engine Operation
• Chapter 8 — Troubleshooting: fuel injection, charging, starting, ignition, lubrication, cylinder, crankcase and exhaust system fault topics
• Chapter 9 — Engine Preservation and Storage: preservation checklist, new/unused engine storage, temporary and indefinite storage of installed and crated engines
• Chapter 10 — Non-Overhaul Repair: magneto installation, accessory drive adapter replacement, oil filter adapter stud replacement, oil pump/tachometer drive repair, oil sump and suction tube repair, oil cooler repair, oil pressure relief valve repair, oil temperature control valve inspection, rocker arm and hydraulic tappet removal, cylinder maintenance, and component service limits
• Chapter 11 — Engine Overhaul Introduction: overhaul sequence, removal and disassembly checklist, visual/fluorescent penetrant/magnetic particle/ultrasonic/dimensional inspection checklists, cylinder and drive train inspection checklists, replacement parts inventory
• Chapter 12 — Engine Disassembly: accessory drive adapter removal, fuel injection system removal by model, induction system removal, exhaust system removal, oil cooler removal
• Chapter 13 — Component Disassembly: starter and adapter disassembly, engine cylinder disassembly, accessory drive pad disassembly, crankcase disassembly, engine drive train disassembly (camshaft, crankshaft, counterweights), compressor mounting kit disassembly
• Chapter 14 — Engine Cleaning
• Chapter 15 — Overhaul Inspection and Repair: engine overhaul inspection, overhaul repair procedures for the fuel injection, induction, alternator, starter/starter adapter, ignition, exhaust and lubrication systems, stud height settings, cylinder repair vs. replacement guidelines, mandatory cylinder overhaul replacement parts, engine drive train parts replacement
• Chapter 16 — Component Assembly: fuel injection system, alternator, starter and starter adapter, exhaust system, lubrication system (oil pump, oil cooler), engine cylinder assembly
• Chapter 17 — Engine Assembly: crankcase hardware, hydraulic valve tappet and pushrod installation, rocker arm installation, cylinder drain tube and baffle installation, oil sump and suction tube installation, oil pump installation, accessory drive pad installation, starter and starter adapter installation, induction, fuel injection, oil cooler and alternator installation by model
• Chapter 18 — Post-Overhaul Test and Engine Operation Prerequisites
• Appendices A through D — including Appendix D overhaul dimensions and service limits for the fuel injection system, starter and starter adapter, ignition system, lubrication system, engine cylinder overhaul dimensions, crankcase, engine drive train, crankshaft counterweight assemblies, connecting rod dimensions, and detailed stud height setting tables and figures for each crankcase part number

Together these chapters give a technician everything needed to service a Permold Series IO-550 engine from the flight line through a complete bench overhaul — scheduled inspections and troubleshooting on one end, and full disassembly, cleaning, dimensional inspection, repair, reassembly and post-overhaul test on the other.

Engine Coverage and Specifications

The Continental IO-550 Permold Series Engine Maintenance and Overhaul Manual documents six-cylinder, fuel-injected, horizontally opposed, air-cooled engines built around the Permold crankcase casting, with a 5.25 in. bore and 4.25 in. stroke giving 550 cubic inches of displacement and an 8.5:1 compression ratio. The IO-550-A, B and C models use an updraft cylinder design, while the IO-550-G, N, P and R models use a crossflow cylinder design with inclined valves. The manual details FAA Type Certificate E3S0, installation drawing numbers for each model, magneto types and timing, spark plug references, exhaust back-pressure limits, and cylinder head temperature limits, along with rated and cruise horsepower figures, oil pressure/temperature limits and sump capacities, fuel system specifications, and dry weight/overall dimension data for every listed model.

Why Technicians and Owners Rely on This Manual

This Continental IO-550 Permold Series Engine Maintenance and Overhaul Manual gives a mechanic the ability to perform correct scheduled inspections, diagnose starting, charging, ignition, fuel and lubrication system faults, carry out non-overhaul repairs on components such as oil coolers, oil pumps, magnetos and starter adapters, and — when the time comes — remove, disassemble, clean, inspect, repair, reassemble and test-run a complete engine overhaul in line with the manufacturer’s Instructions for Continued Airworthiness. Because procedures, torque values, service limits and replacement-parts requirements are specific to the Permold Series IO-550-A/B/C/G/N/P/R family, working from this manual rather than a generic reference helps ensure the work is done to the correct specification. The Continental IO-550 Permold Series Engine Maintenance and Overhaul Manual downloads instantly as a PDF after purchase — no shipping wait, no physical copy to misplace — and can be read on a laptop, tablet, or phone in the hangar or printed for the shop floor.
