This Cessna service manual covers the 1970–1976 210K, T210K, 210L and T210L Centurion series, including Centurion II, Turbo Centurion and Turbo Centurion II configurations. The cover carries D2004-13-RAND-350-2/76 and identifies Change 4, dated October 1, 1975.

Supplied as a single 646-page PDF in English.

• Landing gear and hydraulics: Gear and door rigging, actuator repair, hydraulic power-pack bench testing, pressure adjustments and troubleshooting for both hydraulic configurations.

• Wheels and brakes: Cleveland and McCauley wheel service, wheel-bearing repacking, brake bleeding, wheel alignment and nose-gear shimmy-dampener repair.

• Engine and propeller service: Engine removal and installation, fuel-injection diagnosis, magneto timing, turbocharger control checks and McCauley propeller-governor adjustments.

• Flight controls: Aileron, flap, elevator and rudder cable rigging, elevator trim-tab free-play inspection, electric trim adjustment and simulated air-load testing.

• Electrical systems and instruments: Charging-system troubleshooting, electrical load analysis, pitot-static leak testing, instrument-panel circuits and system-specific wiring diagrams.

• Structural repair: Fuselage, wing and empennage repair criteria, skin and spar repair illustrations, and control-surface balancing after repair or painting.

• Utility systems: Heating and ventilation troubleshooting, wing and propeller de-icing checks, oxygen-system purging, functional testing and leak testing.

Written for mechanics, the manual combines reference information for experienced personnel with step-by-step procedures for those with less experience.

Landing Gear, Brakes and Hydraulic Tests

The landing gear chapter separates the engine-driven hydraulic system through S/N 21059502 from the hydro-electric power pack beginning with S/N 21059503. Separate schematics and troubleshooting charts help match a gear or door sequencing fault to the correct system before selecting tests or replacement components.

Hydraulic repair procedures and exploded assembly views cover uplocks, downlocks, door actuators, manifolds and the emergency hand pump. The Power Pack Bench Test Harness Schematic Diagram supports the valve and handle-release tests; Hydro Test unit instructions cover system and component leak testing.

The manual also warns that excessive filling pressure can damage the power-pack reservoir seals.

Engine, Fuel System and Propeller Service

Separate sections cover the Continental IO-520-L and turbocharged TSIO-520-H engines. Fuel-air control units, fuel manifold valves, injection pumps and discharge nozzles receive component-specific service coverage, supported by the Fuel Injection Schematic.

Turbocharger material covers the controller, waste-gate actuator, troubleshooting and operational checks, with a Turbocharger System Schematic. Propeller coverage includes removal, installation, damage assessment and governor-control rigging.

The airframe fuel-system chapter adds integral fuel-bay leak classification, sealing and testing, plus auxiliary fuel-pump circuit differences and flow adjustment. Major engine repairs and engine, accessory and propeller overhaul require the separate manufacturers' publications.

Airframe, Flight Controls and Inspections

Ground handling, cleaning and lubrication procedures are accompanied by jacking details, reference station diagrams, servicing charts and periodic inspection charts. The inspection section covers 100-hour inspections and explains Progressive Care program selection; the required Progressive Care manuals and forms are separate publications.

Cabin doors, windows, interior upholstery and seat installations are covered alongside wing and empennage work. Structural repair guidance addresses skin, stringer, rib and spar damage, with Control Surface Balancing illustrations and exterior painting information.

Flight-control sections provide cable-tension and surface-travel data, trim adjustments and wear or free-play limits. The torque table distinguishes steel-nut thread sizes and types and states the thread-condition limits for its use.

Electrical, Instruments and Utility Systems

The electrical chapter distinguishes 14- and 28-volt supply systems; the wiring sections are labeled 12-volt and 24-volt. Coverage includes split bus bars, alternator regulation, lighting, warning circuits and electrical load analysis.

Instrument diagnosis includes wet and dry vacuum systems, fuel-quantity calibration and pitot-static testing, supported by the Static System Test Equipment illustration. A specific caution explains how compressed air applied to connected vacuum-system lines can damage the gyros.

Utility-system procedures address de-ice boots, propeller de-icing timers and brush alignment, plus oxygen-system components. Nav-O-Matic autopilot and electronic communications/navigation equipment service information is supplied in separate manuals.

Always consult a certified aviation mechanic before servicing this equipment, particularly the landing gear and flight controls. This documentation is an informational reference.
