Description

Complete Maintenance & Overhaul Guide for Classic Cessna Single-Engine Aircraft

The 1962 & Prior Cessna 100 Series 150 172 175 180 182 185 Service Manual (Publication D138-13) provides 509 pages of exhaustive, authoritative technical procedures for servicing, inspecting, troubleshooting, and repairing the foundational fleet of Cessna high-wing aircraft manufactured through the 1962 model year. Covering the two-place Model 150, four-place 172 Skyhawk, 175 Skylark, 180, and 182 Skylane, as well as the heavy-duty utility Model 185 Skywagon, this service publication establishes the factory standards for maintaining airframe integrity, powerplant systems, mechanical and electrical flight controls, fuel metering, and landing gear assemblies. In addition to primary coverage for 1953 through 1962 models, the technical data serves as an invaluable servicing guide for earlier classic Cessna models such as the 120, 140, and 170.

For the professional aircraft technician, certified A&P mechanic, or dedicated restorer, this publication delivers complete technical clarity. Rather than offering basic field maintenance summaries, the manual delivers exact factory dimensions, tolerances, step-by-step tear-down sequences, component rebuild limits, and rigorous inspection criteria required to keep these vintage single-engine Cessna aircraft in compliant airworthy condition.

Airframe Rigging, Flight Controls & Structural Balance

Proper flight control rigging is critical to the safe operation and cruising performance of all Cessna single-engine aircraft. The 1962 & Prior Cessna 100 Series 150 172 175 180 182 185 Service Manual outlines the precise surface travel specifications, stop screw adjustments, and cable tensiometer readings across all control surfaces. Flight technicians will find detailed procedures for correcting a ‘wing-heavy’ condition utilizing the eccentric wing adjustment bushings located at the front spar wing root attachments, allowing angle-of-attack tuning without altering factory fuselage geometry.

The manual provides explicit surface angular limits: the Model 150 utilizes 20° up and 15° down aileron travel, 39° flap deflection, 16° left and right rudder travel, and 25° up to 15° down elevator travel. On the larger Model 180, 182, and 185 aircraft, technicians are provided with full data for both fixed and adjustable horizontal stabilizers. On models equipped with an adjustable stabilizer for pitch trim, the text outlines the mechanical screwjack travel parameters (such as the 0°45′ up to 8°45′ down stabilizer travel on late 180, 182, and 185 airframes) and instructions for coordinating elevator travel with the stabilizer in the full down position.

In Section 19, the manual presents precise instructions for airframe structural repair, covering spar cap doublers, rib replacement, bulkhead repairs, and the application of skin repair materials. Crucially, the manual provides comprehensive static control surface balancing procedures. Whenever ailerons, elevators, or rudders undergo metal repairs or repainting, technicians can utilize the detailed balance scale charts, jig arrangements, and maximum allowable overbalance/underbalance inch-pound tolerances to eliminate high-speed flutter hazards.

Powerplant, Fuel Injection & Electrical Architecture

Powerplant maintenance instructions span the entire family of Continental aircraft engines installed across early Cessna production. Technicians will find complete service protocols for the four-cylinder Continental O-200-A (rated at 100 HP at 2750 RPM) in the Model 150, the six-cylinder Continental O-300-A, O-300-C, and O-300-D (145 HP at 2700 RPM) in the Model 172 and Skyhawk, and the geared GO-300 series (175 HP at 3200 crankshaft RPM) powering the 175 Skylark. For heavy hauling and backcountry utility, detailed sections cover the Continental O-470 series (225 to 230 HP) in the 180 and 182, as well as the fuel-injected IO-470-F (260 HP at 2625 RPM) featured in the Model 185 Skywagon.

Detailed instructions walk the mechanic through engine removal and replacement, shock mount elastomer inspection, starter drive alignment, generator brush wear limits, voltage regulator point adjustments, and starting vibrator servicing. Ignition system maintenance includes complete timing and overhaul steps for both Bendix-Scintilla and Slick magnetos, including internal E-gap timing, breaker point clearances, and spark plug maintenance. For fuel systems, the manual breaks down gravity-feed carburetor installations alongside the continuous-flow fuel injection architecture of the Model 185, covering fuel/air control unit screens, fuel manifold distributors, injection line purging, and fuel tank sump drain safetying.

Landing Gear Servicing, Wheel Alignment & Brake Overhaul

Landing gear reliability is paramount for commercial training, cross-country flight, and rough-field operations. This manual provides extensive coverage of Cessna’s iconic chrome-vanadium spring-steel main landing gear legs. It covers the multiple fuselage attachment methods utilized across production changes, including U-bolts, wedge-and-shim retainers, and forged channel clamps. Mechanics will find exact instructions for replacing landing gear step brackets using Conley-Weld structural adhesive, complete with surface preparation, mix ratios, clamping pressures, and curing heat cycles.

To prevent premature tire wear and erratic taxi handling, the manual provides complete camber and toe-in alignment specifications for each individual airframe model, accompanied by engineering shim selection charts for correcting gear spring splay. Detailed servicing and overhaul procedures cover both Goodyear and Cleveland main wheels, tube-type and tubeless tires, internal gear-tooth drive discs, floating calipers, and brake master cylinder bleeding. Tricycle gear models receive dedicated instructions for servicing air-oil oleo nose struts, including fluid replenishment with MIL-H-5606 hydraulic oil, inflation pressures (ranging from 20 psi on the 150 to 50 psi on later 182 models), torque link bushing replacement, and shimmy dampener servicing.
