1950–1982 Piper PA-18 & PA-18A Super Cub Illustrated Parts Catalog (P/N 752-451)

This Piper Aircraft Corporation illustrated parts catalog covers the 1950–1982 PA-18 Super Cub and PA-18A Agricultural models. P/N 752-451, revised November 1982, organizes replacement parts into eleven sections, with exploded views, application codes and serial-number listings.

Search, bookmarks and illustration detail: The PDF has searchable OCR text, with gaps and recognition errors in some tables and drawing labels. Embedded bookmarks open the main sections and individual figures. Small numbered callouts in electrical and radio illustrations benefit from zooming.

• Airframe parts: Wing and Fuel Tank Installation illustrations, fuselage framework, exterior panels, fairings, spars, flaps, ailerons and tail-surface components.

• Power plant components: Separate Lycoming and Continental installation groups identify engine mounts, exhaust assemblies, cowls, baffles, oil-cooler plumbing and propeller spinners.

• Flight controls: Elevator, aileron, rudder and flap component listings, plus stabilizer adjustment cables, crank, yoke and bungee assemblies.

• Landing gear and brakes: Hayes wheel and brake drums, Cleveland wheel and brake assemblies, Hydrasorb shock struts, and Scott and Maule tail wheels.

• Agricultural equipment: PA-18A fluid spray pumps, booms, sprayer and duster equipment, hopper, cargo compartment and emergency-dump components.

• Electrical and instruments: Generator and alternator equipment, strobe lights, radio and ELT installations, standard and gyro instrument panels, and wet and dry vacuum systems.

This catalog suits aircraft mechanics and experienced restorers who can interpret illustrated parts lists and configuration codes when planning a repair.

Serial Applicability and Airframe Parts

The “Serial Numbers Affected” column connects individual part numbers to aircraft production changes. Together with equipment codes and assembly quantities, it helps distinguish the parts needed for a particular aircraft before repair parts are ordered.

Wing construction: Fabric and Ceconite listings are separated from the aluminum flap and aileron assemblies used from S/N 18-7809001. Figure 6A, Flap Assembly, and Figure 6B, Aileron Assembly, identify their skins, spars, bulkheads and attachment parts.

Aircraft S/N 18-2520 through 18-2524 have special flap-handle, toe-brake and seat installations. The catalog directs parts identification for these aircraft to separate Piper drawing SK-449.

Brakes, Tail Wheels and Fuel-Valve Changes

Cleveland conversions: Cleveland 30-60 brakes and 40-60 wheels are listed from S/N 18-7609137. They also apply to specified earlier Model 150 aircraft fitted with conversion kit 761-081, so original serial applicability alone does not identify every installed brake configuration.

Scott and Maule tail-wheel listings distinguish assemblies and their internal components. Piper calls for identification from the installed tail-wheel nameplate before replacement parts are ordered.

Fuel valves: Valve 11383-03 and replacement valve 77413-02 use different seal components. The catalog identifies the later parts for earlier aircraft fitted with replacement kit 764-295.

Power Plant and Agricultural Configurations

Engine-installation parts distinguish Continental C-90-8F and electrically equipped C-90-12F configurations, along with the covered Lycoming installations. EDO 89-2000 float applicability notes identify differences in cowling, induction and oil-cooler components.

Working on a crop duster? The PA-18A sections separate Oberdorfer gear-pump equipment from the 3/4-inch and 1-inch Simplex centrifugal-pump configurations. Their application codes distinguish pump hardware, propeller brakes, hopper connections and sprayer-to-duster conversion kits.

Electrical Equipment, Radios and Gyro Systems

The electrical listings distinguish 20-, 35- and 50-amp generator equipment from the later 60-amp alternator installation. Wet vacuum-pump components and dry-pump installations have separate illustrations; the dry system starts at S/N 18-8020.

Radio coverage identifies mounting and connection components for Bendix, Lear, Narco and Genave NAV/COMM installations. Piper Automatic Locator sections distinguish Garrett, Communications Components Corp. and Narco ELT equipment.

Figure 36, Electrical System Installation, and Figure 53A, Radio Installation, Genave, show component locations and numbered parts. These are installation illustrations, not circuit schematics.

Reference Drawings and Repair Limits

Rigging diagrams, aircraft-dimension and control-surface-travel drawings, radio-harness drawings and EDO float-installation drawings are referenced by drawing number; they are not reproduced as separate technical drawing sheets. The included Standard Paint Charts identify original finishes and paint part numbers.

This is a parts-identification reference, not a step-by-step repair manual. Piper expressly prohibits using the catalog for rigging or installation. Check current part supersessions and applicable FAA airworthiness directives before installing components or returning an aircraft to service.
