Suzuki GV700GL Madura 1984 Service Manual (P/N 99500-36040-03E)

This 303-page PDF contains Suzuki's factory service manual for the GV700GL, Manual No. 99500-36040-03E, prepared by Suzuki Motor Co., Ltd.'s Service Publications Department and dated April 1984. It is dedicated to the GV700GL configuration: a liquid-cooled, DOHC TSCC 82-degree V-four, hydraulically operated wet multi-plate clutch, six-speed constant-mesh transmission, shaft drive, Full-Floater rear suspension, and fully transistorized ignition. Suzuki states that the manual was produced primarily for experienced mechanics, while apprentice and do-it-yourself mechanics can also use it as a repair guide; the overhaul sections assume sound workshop practice, precision measuring equipment, and access to the specified tools.

• Engine overhaul: Covers compression testing, engine removal and installation, complete disassembly and reassembly, cylinder-head and valve work, hydraulic lash adjusters, camshaft timing, pistons and rings, connecting-rod and crankshaft bearings, clutch service, and transmission-shaft repair.
• Shaft-drive setup: Details the secondary bevel gears, propeller shaft, and final gear case, with removal, teardown, inspection, bearing-preload setup, shim selection, backlash measurement, tooth-contact correction, and final assembly.
• Fuel and emissions: Provides fuel-pump and relay tests plus Mikuni BDS33SS carburetor construction, circuit operation, disassembly, float and fuel-level adjustment, and four-carburetor synchronization. The emission section distinguishes the close-tolerance jets and the sealed, factory-preset pilot-screw setting.
• Cooling and lubrication: Explains cooling-system leak and pressure checks, radiator-cap testing, thermostat inspection, water-pump repair, fan-switch and relay diagnosis, temperature-gauge testing, oil-pressure checks, sump-filter service, and lubrication routing.
• Electrical diagnosis: Addresses the charging system, AC generator, regulator/rectifier, transistorized ignition, signal generator, ignitor, starter motor and relay, instruments, indicator circuits, switches, battery, and the revised full-system wiring diagram.
• Chassis and scheduled service: Includes the factory maintenance schedule, wheel and brake repair, caliper and master-cylinder rebuilding, brake and clutch bleeding, front-fork overhaul, steering-stem bearings, rear suspension, swingarm, routing views, torque tables, and system-based troubleshooting.

Engine Overhaul and Shaft-Drive Setup

The engine material distinguishes the front and rear cylinder banks and identifies the four camshafts by their E, F, G, and H markings. Plastigage checks and code-based bearing selection cover the connecting rods and crankshaft journals, with a separate process for thrust-bearing selection. Cylinder and piston inspection, valve-seat cutting, valve-guide replacement, and transmission-shaft rebuilding have their own procedures. Reassembly coverage calls out the timing chains, oil jets, seals, retainers, and specified locking compounds. The oil-pump section also sets a clear scope limit: Suzuki warns that dismantling the thread-locked pump assembly may damage its screws, and only the complete pump unit is supplied for replacement.

Component-specific cautions matter during repair. The manual warns that the hydraulic lash adjusters must be bled with kerosene; using solvent, another fluid, or oil can cause engine damage. It also warns that driving a replacement valve guide into a dry guide bore can damage the guide or cylinder head. In the shaft drive, secondary and final drive/driven bevel gears are treated as matched pairs, and backlash must be checked again after correcting tooth contact.

Diagrams, Suzuki Tools, and Service Data

Named visual references include Secondary Bevel Gears Construction, Propeller Shaft Construction, Final Gear Case Breather Circuit, Carburetor Construction, and the Lubrication System Chart. Separate routing plates map the cables, main wiring harness, brake and clutch hoses, water hoses, and secondary-gearcase breather for correct reinstallation.

The 82-item special-tool catalog supplies factory part numbers and flags tools that were unavailable in the USA at publication. Notable examples are lash-adjuster air-bleeding tool 09913-10710, carburetor balancer 09913-13121 with adapter 09915-94511, and final-drive backlash measuring tool 09924-34510. The same list identifies ignitor checker 09930-70710 and fork-oil-seal installer 09940-50112.

The closing reference section consolidates component-specific torque tables, approved fluids and capacities, wear limits, clearances, bearing and shim data, carburetor settings, and electrical test specifications. Symptom/cause/remedy charts cover the engine, shaft drive, carburetors, radiator, charging and starting systems, battery, chassis, and brakes. Engine removal, wheel and suspension repair, hot cooling-system service, gasoline handling, and hydraulic brake or clutch work require stable support, proper shop equipment, and close adherence to the factory warnings.
