Yamaha Maxim XJ700 1985–1986 Service & Owner’s Manual Set (P/N LIT-11616-04-85)

Use the S/SC supplement together with the N/NC service publication, as Yamaha specifies. The separate owner’s handbook covers operating controls, pre-ride checks, riding, basic maintenance, and storage for N/NC models only.

PDF Files, Search, and Wiring Detail

Search and diagram navigation: The service PDF has searchable OCR text and chapter bookmarks. The Owner’s Manual has no text search, and its Maintenance Record bookmark points to the cover. Small service-manual wiring labels require zooming; some fine labels and lines in the owner’s wiring diagram remain faint when enlarged.

The ZIP download contains two printable PDFs totaling 319 pages, including one added collection cover, one unrelated wiring-diagram page, and two promotional pages. The Owner’s Manual mostly places two printed pages on each PDF page.

Engine, Chassis, and Electrical Service

The following selected content highlights summarize the main workshop coverage; additional topics include headlight aiming and fuse checks.

• Engine overhaul: Engine removal, top- and bottom-end disassembly, valve-guide and seat repair, camshaft and timing-chain setup, and piston and crankshaft inspection.

• Clutch and transmission: Clutch repair, oil-pump inspection, transmission-shaft and gear checks, shift-fork inspection, and assembly procedures.

• Carburetion and tune-up: Carburetor overhaul, float-height and fuel-level adjustment, Y.I.C.S. synchronization, valve-clearance adjustment, ignition-timing checks, and compression testing.

• Wheels and brakes: Wheel-bearing replacement, rear drum-brake inspection, front-caliper and master-cylinder repair, brake-pad replacement, and hydraulic bleeding.

• Suspension and shaft drive: Fork overhaul, steering-head bearings, swingarm and rear-shock service, middle-drive overhaul, and final-drive gear-lash and shim adjustment.

• Electrical diagnosis: Starting, charging, ignition, lighting, and signal-system troubleshooting, supported by wiring diagrams, component-location drawings, and electrical test data.

Yamaha wrote the service publications for dealers and qualified mechanics with a working knowledge of motorcycle repair; the owner’s handbook supports operating checks and basic maintenance.

Engine Overhaul and Assembly References

Step-by-step overhaul procedures include Plastigage checks for crankshaft and connecting-rod bearing clearance, bearing-selection charts, cylinder inspection, valve-seat cutting and lapping, and final engine assembly and adjustment.

The clutch section warns that misaligned oil-pump drive-sprocket tabs can be damaged when the clutch-boss nut is tightened. Assembly notes also address keeping crankcase sealant away from the oil-gallery O-ring and crankshaft bearings, and preventing oil-ring expander ends from overlapping.

Special tools: References identify tappet adjusting tool YM-01245, universal clutch holder YM-91042, middle-drive pinion holder YM-33222, dial gauge YU-03097, and fork-service tools YM-01326/YM-33298. Further tool listings cover generator removal, steering work, and electrical testing.

Carburetor Setup and Periodic Maintenance

The Hitachi HSC33 carburetor section includes a Main Metering System section view and separate inspection criteria for diaphragms, vacuum pistons, needles, valve seats, and jets.

Synchronization uses the Y.I.C.S. shutoff tool YM-08025 and vacuum gauge YU-08030. Yamaha specifies checking valve clearance first, connecting valve adjustment and carburetor setup when investigating uneven running.

Maintenance coverage also includes spark plugs, California canister and hose checks, crankcase ventilation, intake and exhaust inspection, engine-oil and filter replacement, clutch adjustment, final-gear oil, battery care, and control-cable lubrication.

Chassis Repair and Final-Drive Setup

Fork and steering procedures include seal and bushing replacement, bearing inspection, and steering adjustment. Shaft-drive coverage adds symptom-based troubleshooting, oil-leak checks, ring-gear positioning, thrust-clearance measurement, and shim selection.

Dimensioned drawings for Press Tool No. 1, Press Tool No. 2, and the Gear Case Holding Tool support fabrication of final-drive service fixtures. The diagnosis section links acceleration-dependent whining after reassembly to insufficient gear lash, which can damage the gear teeth.

Engine removal, fuel-system work, brake service, and battery maintenance involve heavy components and hazardous fluids. Support the motorcycle securely, isolate electrical power, keep ignition sources away from fuel, and use suitable eye and hand protection.

Electrical Fault Isolation

Starting Circuit Operation drawings explain the neutral, clutch, and sidestand interlocks. Charging-voltage checks and ignition troubleshooting charts connect symptoms with wiring, coil, relay, and regulator tests.

Signal-system coverage includes self-canceling turn signals, oil-level and fuel-warning lights, the fuel sender, horn, and switches; the S/SC supplement revises fuel-warning diagnosis. Lubrication Diagram and Cable Routing drawings support reassembly and correct hose and harness placement.

Selected Valve-Clearance and Gear-Lash References

For cold valve-clearance checks, the N/NC service section specifies 0.11–0.15 mm intake and 0.16–0.20 mm exhaust, with separate pad-selection charts.

Final-drive specifications distinguish actual tooth lash of 0.10–0.20 mm from a 0.25–0.50 mm reading with the specified measurement tool and the dial gauge positioned 60 mm from the shaft center.
