Honda CB750K/F/C/SC Factory Repair Manual Set, 1979–1983

The addendums work with the base manual and earlier sections, supplying model-specific changes rather than repeating unchanged procedures.

Coverage ends with the 1982 model year; 1983 models are not covered. Tubeless-tire repair is referred to a separate Honda manual, which is not included.

PDF Access and Wiring Detail

Search, navigation, and diagram labels: PDF text search and embedded bookmarks are not available. Small wiring-diagram labels need magnification, and some wire-color codes and component labels remain difficult to read when enlarged.

The ZIP contains one printable English PDF with 442 pages, including the base manual, all six addendums, 16 memo pages, and one blank page. These additional pages are already included in the total.

Engine Overhaul, Carburetor Service, and Electrical Testing

The following selected service topics outline the repair coverage. Other documented work includes control-cable replacement and headlight and instrument servicing.

• Engine repair: Engine removal and installation, DOHC cylinder-head and camshaft work, valve-guide replacement, seat refacing, cylinder/piston inspection, and crankcase separation.

• Carburetor service: VB carburetor-bank separation, vacuum-cylinder and float-chamber work, air-cutoff valves, accelerator pumps, linkage assembly, and synchronization.

• Clutch and transmission: Clutch and starter-clutch disassembly, external shift-linkage service, internal transmission inspection, and shift-drum and shift-fork work.

• Chassis and brakes: Wheel bearings, steering-stem service, fork repairs, model-specific swingarm procedures, shock inspection, brake bleeding, and master-cylinder and caliper overhaul.

• Electrical diagnosis: Model-specific wiring diagrams, harness routing, charging and transistorized-ignition tests, starter-circuit checks, switch continuity, and CB750SC fuel-gauge diagnosis.

• Workshop reference data: Component torque tables, fluid capacities, adjustment specifications, pressure checks, electrical test values, and standard dimensions with wear limits.

With select-fit bearing work and live electrical testing, this set is suited to professional technicians and mechanically qualified owners equipped for metric repairs. Honda recommends authorized-dealer service for certain safety-related maintenance items.

Engine Teardown and Bearing Selection

Oil-pressure troubleshooting is supported by oil-pump removal, rotor inspection, assembly, and lubrication-system checks. Top-end procedures address valve lifters, cam timing, shim adjustment, and cam-chain tension.

Crankshaft and connecting-rod bearing selection uses identification codes and color tables, followed by Plastigauge clearance verification. Primary-shaft service includes the damper and primary-chain tensioner.

The cylinder-head instructions identify two assembly risks: damage to new valve-stem seals and loss of valve-spring tension from excessive compression.

Fuel Delivery and Driveability Diagnosis

Step-by-step carburetor procedures cover disassembly and reassembly, with separate adjustments for float level, fast idle, pilot screws, choke operation, and synchronization. Symptom charts connect starting and running complaints with fuel supply, ignition, and compression checks.

The 1981 addendum adds fuel-line diaphragm troubleshooting, vacuum testing, and tube-routing illustrations. This distinguishes faults in the fuel supply from problems inside the carburetors. The 1982 material also addresses slow-jet service and high-altitude adjustment.

Suspension and Brake Variants

Wheel and suspension material includes hub and rim inspection, bearing replacement, fork seals and bushings, steering-head bearings, and shock-spring checks. The 1980 K/F addendum contains needle-bearing swingarm disassembly and assembly; the original CB750K swingarm procedure listed in the base manual is absent from this PDF.

Later sections describe air-assisted front forks, adjustable CB750F F.V.Q. rear shocks, and CB750SC T.R.A.C. anti-dive disassembly and inspection. Shock servicing covers the spring and external components; Honda instructs against dismantling the sealed damper.

Brake coverage distinguishes CB750F front and rear hydraulic systems from the other configurations. The 1982 K/C material identifies Type I and Type II calipers with different pads and inspection specifications, helping match service information to the installed brake assembly.

The CB750SC front-wheel instructions warn that incorrect caliper-holder-to-disc clearance can damage the discs and impair braking.

Electrical Fault Finding, Illustrations, and Tools

Electrical tests address the battery, generator, regulator/rectifier, ignition coils, pulser generator, spark units, starter motor and relay, and switches. CB750SC procedures distinguish fuel-gauge function testing from sender inspection.

Factory illustrations include the lubrication-system flow view, carburetor and accelerator-pump assemblies, camshaft/cylinder-head layouts, transmission and shift-drum/shift-fork views, front-fork and steering-stem assemblies, and the T.R.A.C. mechanism.

Tool lists provide names, part numbers, and section references. Examples include primary gear holder 07924-4220000, rotor puller 07933-4250000, vacuum gauge set 07404-0020000, and oil-pressure gauge 07506-3000000 with attachment 07510-4220100.

Fuel-system, battery-charging, hydraulic-brake, and spring-loaded fork work should follow the manual’s safety precautions and final operational checks before a test ride.

Selected Ignition and Fuel-Sender Test Values

The base ignition section specifies pulser-generator coil resistance of 530 ± 50 Ω at 20°C (68°F), with separate lead-pair identification for the two ignition circuits.

For the 1982 CB750SC, sender resistance is specified as 1–6 Ω with the float at F (FULL) and 103–117 Ω at E (EMPTY). These are sender-position checks; the separate fuel-gauge function test uses measured fuel quantities and gauge readings.
