1977–1981 Cessna R172K & FR172K Hawk XP / XP II Illustrated Parts Catalog (P698-12)

Cessna Illustrated Parts Catalog P698-12, issued October 1, 1996, covers the 1977–1981 R172K and Reims/Cessna FR172K Hawk XP and Hawk XP II. This reissue replaces P669-12 and its temporary revisions. Its purpose is replacement-parts identification.

• Airframe structure: Wing assemblies, wing struts, fuselage bulkheads, fin and rudder assemblies, with separate illustrations for conventional fuel tanks and integral fuel cells.

• Landing gear and brakes: Main and nose gear breakdowns, shimmy dampener components, master brake cylinders, and wheel/brake combinations with application notes.

• Flight controls: Aileron and elevator bellcranks, rudder and trim systems, flap actuators, and the floatplane rudder-aileron interconnect.

• Engine and fuel equipment: Continental engine mounts and accessories, induction air box, exhaust, propeller/spinner installation, fuel strainers, and selector-valve parts.

• Electrical equipment and instruments: Battery boxes, alternator components, strobe lighting, instrument clusters, and pitot and vacuum system parts with installation illustrations.

• Cabin and trim: Pilot and passenger seat assemblies, interior panels, cabin heating and ventilation, finish/trim charts, and registration-marking guides.

Suited to aircraft maintenance technicians and parts personnel who can match illustrated assemblies and applicability codes to an aircraft's configuration.

Serial Applicability and Parts Lookup

The alphabetical and numerical indexes connect component names and part numbers to figure/index references. Exploded views and installation drawings identify items in the group assembly lists, where indentation distinguishes assemblies, subassemblies, and attaching hardware.

The catalog's Usable On codes separate US-built and Reims/Cessna serial blocks. Each figure has its own code definitions, helping parts staff distinguish noninterchangeable components before ordering. The introductory notes also explain WEU replacement references and items marked NP as nonprocurable.

Airframe, Fuel Cells and Landing Gear

Wing Structure Assembly – Integral Fuel Cell and Fuel Valve Assemblies show the relevant structural and valve components. Integral-cell listings distinguish installations with and without SK172-119; the catalog directs readers to the service manual for repair and sealing procedures.

Main Landing Gear Wheel & Brake Assembly includes explicit wheel/brake pairing restrictions. Replacement hardware for landing gear and flight controls must match the specified aircraft application before return to service.

Floatplane Fittings Installation and Rudder-Aileron Interconnect System–Floatplane identify the listed factory floatplane equipment. Inspection, maintenance, and parts requirements for STC installations are outside this catalog's coverage.

Powerplant, Instruments and Electrical Equipment

Engine Installation & Assembly details mounts, shock mounts, and controls. The engine-accessory list identifies Bendix Scintilla magnetos, ignition harnesses, starters, and fuel-injection components. It refers readers to the Continental parts catalog for engine components outside that list.

McCauley propeller details also require a separate manual. Autopilots, avionics communications, and navigation equipment are covered by separate publications, although associated panel hardware and some instruments appear here.

The electrical pages provide component installation views rather than circuit troubleshooting diagrams. Battery-polarity placards warn that reversed polarity can damage electrical components.

Finish, Trim and Ordering Details

The publication explains finish and trim plates, exterior paint combinations, and interior upholstery codes. Upholstery & Interior Trim describes second-dash-number selection for upholstered, painted, and plastic parts, with separate ordering rules for earlier and later interiors.

Registration-marking pages distinguish slanted and vertical Gothic stencils from adhesive-backed vinyl decals. Bulk-item notes identify material types and cut lengths used in individual installations.

Selected Fuel-and-Oil Hose Sizes

The following fuel-and-oil hose entries are two examples of the component dimensions provided for parts identification. The bulk-material listing specifies a 1/4-inch inside diameter for S51-4 and a 3/8-inch inside diameter for S51-6.

PDF Indexes, Readability and Page Count

Search and drawing detail: PDF text search and embedded bookmarks are unavailable. Navigation uses the printed alphabetical and numerical indexes. Small callouts in dense assembly views benefit from zooming; some fine lettering on the operating-limitations placards remains indistinct even when enlarged.

Supplied as one printable, English-language 432-page PDF: one title page, one effective-page list, 36 preliminary pages, and 394 catalog/index pages. The 21 blank pages are already included in that total.
