1986 Kawasaki ZL 500/600 Service Manual (P/N 99924-1073-51)

• Genuine Kawasaki factory publication Part No. 99924-1073-51, supplied as a 131-page PDF, for the 1986 ZL500-A1 European model and ZL600-A1 US and non-US models.
• Coverage starts at frame ZL500A-000001, ZL600A-000001, or US VIN JKAZL4A1[variable digit]GA000001; the manual distinguishes European, US, Canadian, California, and Swiss specifications where applicable.
• Fuel and cooling sections cover ZL500/ZL600 Keihin CVK30 calibration differences, throttle adjustment, carburetor-bank removal, surge-tank and air-cleaner service, fuel-tank removal, California evaporative-emission components, coolant replacement, radiator/fan removal, hose routing, and thermostat-housing service.
• Engine and clutch material includes cylinder-head-cover access, model-specific camshaft timing marks, valve-clearance adjustment, piston-ring orientation, engine removal/installation, clutch-pack removal and inspection, spring-plate free-play setup, and the deceleration torque-limiting clutch.
• Shaft-drive repair receives a full chapter covering the final and front bevel gear cases, propeller shaft, damper cam, bearing preload, shim selection, backlash measurement, tooth-contact adjustment, inspection, and reassembly.
• Chassis and electrical coverage includes wheel removal, rear hub bearings, rear drum-brake service, fork overhaul, shock adjustment, swingarm alignment, steering work, system circuit tests, cable and harness routing, and separate full wiring diagrams for US/Canada and other markets.

Model-Specific Factory Coverage

This Kawasaki manual records the A1-generation changes needed to service the ZL500 and ZL600 correctly rather than treating them as interchangeable motorcycles. The general, carburetor, suspension, tire, lighting, junction-box, emissions, and electrical data use market symbols to distinguish Canadian, California, US, and Swiss variations. Its concise factory procedures, specialty-tool requirements, and frequent cross-references make it best suited to experienced motorcycle technicians or advanced owners with proper lifting and measuring equipment and access to the separate Base Manual.

Engine, Clutch, and Final-Drive Repair

The engine sections document access and removal work specific to the Eliminator chassis. They cover carburetor-bank extraction, surge-tank and air-cleaner housing removal, radiator and thermostat-housing work, cylinder-head-cover clearance, revised camshaft-sprocket reference marks, valve adjustment, muffler removal, oil-filter access, and complete engine removal and installation. The crankshaft/transmission chapter supplies ZL-specific exploded-view changes for the drive and output shafts, including the toothed washer and damper-cam arrangement.

Clutch coverage goes beyond a basic cable adjustment. It explains the deceleration torque-limiting design, clutch cover and pack removal, spring-plate free-play measurement, steel-plate selection, wear checks, and damper-cam inspection. One important repair trap is called out directly: pulling the clutch release shaft during cover removal damages the cover oil seal and requires seal replacement.

The final-drive chapter provides standalone procedures for rear final-gear-case and front bevel-gear-case removal, disassembly, bearing and oil-seal work, propeller-shaft inspection and lubrication, and damper-cam service. It also provides the factory preload, backlash, shim, and tooth-contact procedures. Kawasaki specifies that the ring and pinion are factory-lapped as a pair; replacing only one gear or reinstalling the original shims in the wrong positions can upset contact and damage the drive. The manual also warns that torch-heating a gear case can warp it.

Chassis, Electrical, and Reference Data

Chassis material covers front and rear wheel removal, rear coupling and hub-bearing work, rear brake-pedal and cam-lever adjustment, brake-panel disassembly, front-fork oil service and overhaul, rear-shock settings, swingarm removal and alignment, and steering-stem service. The tire table identifies the specified Dunlop F17G and K255 applications with sizes, pressures, tread limits, and market-specific load data.

Representative illustrations include the engine-oil flow chart, final-gear tooth-contact patterns, US/Canadian and European headlight circuits, tachometer circuit, coolant-temperature warning circuit, and full wiring diagrams for US/Canada and other markets. Diagnostic material covers the junction-box fuse, relay, and diode circuits; starter and charging circuits; tachometer and warning-system checks; switch connections; and harness routing. Specification tables provide component torques, capacities and approved fluids, service limits, clearances, adjustment data, shim selections, electrical test values, and a periodic maintenance schedule. Named Kawasaki tools include valve-adjusting-screw holder 57001-1217, clutch holder 57001-305, pinion-gear holder 57001-1164, dial-gauge holder 57001-1049, and front-fork cylinder tools 57001-183 and 57001-1057.

Base-Manual Dependency and Factory Safety Notes

This PDF is not a fully self-contained manual set. Chapter entries marked “Refer to Base Manual” direct many operations—including full carburetor synchronization and overhaul, water-pump repair, most internal engine and transmission work, front caliper and master-cylinder repair, and numerous electrical component tests—to a separate Kawasaki Base Manual that is not included here. This publication supplies the ZL-specific specifications, changes, diagrams, routing, and procedures that are printed on its own pages.

Factory safety notes address secure hoist support, the warning not to place a stand under the exhaust power chamber, fuel and hot-coolant hazards, a radiator fan that can run with the ignition off, and asbestos precautions for rear brake-lining work.
