1956–1962 Cessna 172 / 175 Illustrated Parts Catalog

This Cessna illustrated parts catalog covers the 1956–1962 172, 172 Skyhawk, 175, and 175 Skylark. Publication P257-12 is dated February 15, 1963, with Temporary Revision 1 and Temporary Revision 2 material included.

Text search and catalog navigation: The PDF has a partial OCR text layer and six bookmarks for its main sections. Many part-number fields, numerical-index entries, and revision-cover details are not searchable. Check numbers against the page images; PDF page 120 is upside down and requires viewer rotation.

• Airframe structures: Wing Structure Assembly drawings and illustrated listings for fuselage sections, fin and dorsal assemblies, stabilizers, rudders, and elevators.

• Flight controls: Aileron Control System Installation drawings, rudder and elevator cable routing, flap mechanisms, and elevator trim components with attaching hardware.

• Landing gear and brakes: Nose-gear struts, shimmy dampeners, main-wheel and brake breakdowns, master brake cylinders, and wheel-alignment shim charts.

• Engine and propellers: Continental engine installations, baffles, exhaust stacks, and engine controls, plus fixed-pitch propeller listings and McCauley Propeller Assembly breakdowns.

• Fuel and lubrication: Main and auxiliary tank installations, vent lines, Fuel Selector Valve Assembly drawings, fuel strainers, six-cylinder priming, and oil-system components.

• Instruments and electrical equipment: Pitot System Installation drawings, instrument-panel layouts, venturi and engine-driven vacuum systems, rotating beacons, and stall warning indicators.

• Optional equipment: Tactair autopilot installations, floatplane fittings, ski landing-gear axles, winterization equipment, oxygen systems, dual venturi setups, and speed fairings.

This catalog is suited to aircraft mechanics and parts personnel familiar with airframe serial numbers and figure-specific parts-catalog usage codes.

Serial-Specific Parts Selection

Illustration callouts identify parts in the accompanying lists; the listed part number is the ordering reference. Cessna Standard hardware, vendor references, assembly quantities, and alternate-part notations appear alongside the component descriptions.

Usable-on codes apply only to the figure where they appear. Skyhawk- and Skylark-specific parts supplement or replace the corresponding basic-model items. Checking those codes against the aircraft serial number helps distinguish similar components before ordering repair parts.

Engine, Propeller and Landing Gear Variants

The engine listings distinguish Continental O-300-A, O-300-C, and O-300-D installations for the 172 series from GO-300-A, GO-300-C, GO-300-D, and GO-300-E installations for the 175 series. Coverage concerns installed engines and their associated equipment, rather than internal engine overhaul.

For 175 Skylark serials 17557003–17557119, separate illustrations cover the McCauley constant-speed propeller and its governor. Other propeller listings distinguish landplane and floatplane applications.

Nose-gear listings separate original and redesigned forks, their fairings, and cover plates. The catalog specifically excludes cover plate 0542117-5 from use with fairing 0743609-17.

Brake-system listings distinguish NF-thread and pipe-thread master-cylinder fittings, a useful check when selecting components for a repair.

Equipment Drawings and Catalog Limits

Fuselage Electrical Equipment Installation drawings identify equipment locations and mounting hardware. Electrical wiring diagrams and wire tables are excluded: the deletion notice for Figures 94–97 directs users to the maintenance manual. Radio and Nav-O-Matic references point to separate Cessna electronics documentation.

The exploded views identify components and their relationships; they do not establish a disassembly or reassembly sequence. This parts catalog does not provide repair procedures, troubleshooting tests, or internal engine overhaul instructions. Consult a qualified aircraft mechanic before flight-critical repair work.

Accessory-kit listings identify model and serial applicability. The introduction distinguishes factory installations from field-installed AK kits and directs readers to the applicable kit instructions for field-installation details.

Finish, Trim and Revision Changes

Paint and upholstery combination charts explain the finish-and-trim plate codes, including exterior paint and interior trim colors.

Temporary Revision 1 includes the corrected aileron push-rod-end listing on printed page 25. Temporary Revision 2 supplies separate corrections to part numbers and serial-usage codes, including a fuel-selector O-ring substitution. Those correction sheets need to be read alongside the original listings.

PDF Contents and Included Revision Pages

One printable, English-language 445-page PDF contains 435 pages from the introduction through the numerical index, including 36 intentionally blank pages and the revised page 25 from Temporary Revision 1. The remaining 10 opening pages comprise one cover, one revised-page register, five temporary-revision cover/correction pages, and three blank or logo-only pages; all are already included in the total.
