1979–1983 Honda CB750K, CB750F, CB750C, and CB750SC Factory Repair Manual (P/N 4496 8206)

• Factory publication and file structure: Honda Motor Co., Ltd. shop manual, publication reference MSV 4496 8206, supplied as a 442-page PDF. The base material was issued in August 1978, with dated model-year addendums and revised pages through June 1982.
• Exact model coverage: 1979 CB750K, CB750K LTD, and CB750F; 1980-1981 CB750K, CB750C, and CB750F; 1982 CB750K, CB750C, CB750F, and CB750SC. Coverage ends with the 1982 model year; this publication does not cover 1983 models.
• Engine repair procedures: Covers engine removal and installation, DOHC 16-valve cylinder-head and camshaft service, valve-guide replacement and seat refacing, cylinder and piston work, crankcase separation, and color-coded crankshaft and connecting-rod bearing selection.
• Fuel and drivetrain work: Details VB carburetor-bank removal and separation, vacuum-cylinder, float-chamber, air-cutoff-valve, and accelerator-pump service, linkage assembly and synchronization, clutch and starter-clutch repair, and transmission/shift-drum/shift-fork service.
• Chassis and brake service: Documents wheel and bearing work, steering-stem repair, fork and swingarm service, shock inspection, brake-fluid replacement and bleeding, master-cylinder and caliper overhaul, model-specific tubeless-wheel procedures, and CB750SC T.R.A.C. anti-dive inspection.
• Electrical diagnosis and reference data: Provides model-specific wiring diagrams and harness routing; charging-system, transistorized-ignition, starter, switch-continuity, and CB750SC fuel-gauge tests; plus torque tables, capacities, clearances, wear limits, pressure checks, and electrical specifications.

Honda organized this publication around the CB750K base shop manual, with sequential addendums for model- and year-specific changes. Later addendums are not stand-alone: they send the mechanic back to the base sections and earlier addendums for unchanged procedures. With full engine teardown, select-fit bearing data, live electrical testing, and Honda special tools, this manual is best suited to professional technicians and experienced owners comfortable with metric motorcycle repair.

Engine, Fuel, and Drivetrain Depth

The engine chapters go beyond scheduled maintenance. Oil-pressure diagnosis leads into oil-pump removal, inspection, assembly, and lubrication-system checks. Top-end coverage follows camshaft and cylinder-head removal through valve and lifter inspection, guide replacement, seat refacing, reassembly, cam timing, and final valve and cam-chain adjustment. Lower-end chapters cover crankcase splitting, connecting rods, the primary shaft and chain tensioner, and select-fit main and rod bearing identification with Plastigauge verification.

Fuel-system service follows the four-carburetor bank from removal and separation through vacuum pistons, float chambers, air-cutoff valves, the accelerator pump, and throttle linkage. Factory adjustments address float level, fast idle, pilot screws, choke operation, and carburetor synchronization. Symptom-based troubleshooting links starting and driveability faults to fuel, ignition, and compression checks. Clutch and starter-clutch procedures are separated from external shift-linkage work and internal five-speed transmission repair.

Chassis, Brake, and Electrical Coverage

Wheel and suspension chapters cover bearing replacement, hub and rim inspection, fork seal and bushing work, steering-head service, the swingarm, and shock-spring checks. Model-specific sections address CB750F front and rear hydraulic brakes, 1981 front-fork air-pressure service, and the 1982 CB750SC T.R.A.C. system. The 1980 CB750C section covers tubeless-wheel handling, but Honda refers puncture repair to the separate Honda Motorcycle Tubeless Tire Repair Manual.

Electrical material combines model-specific circuit drawings with on-motorcycle tests for the battery and charging system, generator, voltage regulator/rectifier, ignition coils, pulser generator and spark units, starter motor and relay, and motorcycle switches. The CB750SC addendum adds fuel-gauge and sender testing.

Factory Illustrations, Tools, and Addendums

Representative factory illustrations include the engine 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 exploded assemblies, and the CB750SC T.R.A.C. mechanism. Model-specific wiring diagrams and cable/harness routing views support electrical diagnosis and correct reassembly.

Honda tool listings give 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.

The 442 PDF pages are allocated as follows: 257 pages for the base manual; 56 for the 1979 K LTD/F addendum; 30 for the 1980 K/F addendum; 14 for the 1980 C addendum; 48 for the 1981 K/C/F addendum; 12 for the 1982 K/C/F addendum; and 25 for the 1982 SC addendum.

The cylinder-head section warns that forcing a valve through a new stem seal can damage the seal and that overcompressing a valve spring can reduce its tension. The CB750SC front-wheel instructions require a caliper-holder-to-disc clearance check after installation because misalignment can damage the brake discs and reduce braking efficiency. Fuel-system, battery-charging, hydraulic-brake, and spring-loaded fork work should be performed with the manual's safety precautions and final operational checks in place before a test ride.
