1988–2000 Honda GL1500 Gold Wing, Aspencade & SE Shop Manual (P/N 61HB903)

• Exact factory coverage: Base GL1500 shop manual plus the K, L, M, N, P, R, S, V, and W addenda. The N supplement covers GL1500 and GL1500SE; P through W identify GL1500A and GL1500SE. Regional information includes the SW Switzerland specification where listed.
• Engine and driveline repair: Covers engine removal and installation, cylinder heads, camshafts, hydraulic valve adjusters, timing belts, clutch service, alternator drive, output shaft, transmission, crankcase separation, pistons, connecting rods, crankshaft bearings, and final-drive overhaul.
• Fuel, cooling, and emissions systems: Details dual CV carburetor separation and assembly, synchronization, pilot-screw adjustment, fuel pump and auto-cock testing, carburetor control systems, cooling-system diagnosis, water-pump service, and SW-specific secondary-air equipment.
• Chassis repair procedures: Includes unified hydraulic brake diagnosis and bleeding, master cylinders and calipers, wheel and steering-stem service, fork and shock repair, swingarm work, the onboard air-compressor system, and final-drive gear contact and backlash inspection.
• Electrical and control-system diagnosis: Provides circuit-level troubleshooting for charging, computerized ignition, starter/reverse, electronic cruise control, audio, lighting, instruments, and self-canceling turn signals, along with cable, harness, connector, and vacuum-hose routing views.
• Factory specifications and tooling: Supplies component torque tables, fluid data, wear limits, inspection clearances, electrical test values, adjustment data, troubleshooting charts, and Honda special-tool numbers for the covered repair operations.

This factory shop manual set begins with Honda’s April 1988 GL1500 publication and incorporates nine later model-code addenda in the same PDF. Honda states that detailed explanations of standard workshop practices are not included, so the material is suited to qualified mechanics and experienced owners who already have proper shop equipment and understand normal service methods. It is not written as a beginner’s introduction to motorcycle repair.

Document Makeup

The addenda document actual model changes rather than merely repeating the base specifications. K and L revise major fuel, cooling, ignition, reverse, cruise-control, and instrument procedures. M adds changed service data, hose routing, fuel troubleshooting, and air-system information. From N onward, GL1500 and GL1500SE specifications are separated; P and later supplements identify GL1500A and GL1500SE applications. Later repair updates address camshaft-holder assembly, starter/reverse controls, fader and cruise circuits, fork service, clutch and transmission work, piston installation, and regional lighting circuits.

Diagrams, Testing, and Shop References

Named diagnostic material includes the fuel-system circuit diagram, air-system circuit diagram, onboard air-compressor circuit, charging-system schematic, starter/reverse system diagram, and cruise-control circuit. Most major sections begin with an assembly or system view, service information, and a troubleshooting chart before moving into the detailed removal, inspection, and reassembly procedures.

The tool index identifies application-specific equipment rather than leaving the mechanic to infer substitutes. Examples include hydraulic tappet bleeder 07973-MJ00000 or 07973-ME90000, clutch center holder 07JMB-MN50300, crankcase assembly guide 07JMG-MN50200, and pinion joint holder 07924-ME40000.

Two repair cautions are especially important. The cylinder-head section warns that oil contamination or tight bending can swell or fracture the timing belts and compromise cam timing. During crankcase separation, the pistons can drop against the transmission gears or crankcase if they are not protected, causing component damage.

Engine removal requires a floor jack or equivalent adjustable support, while wheel and suspension work calls for secure support at the factory-specified points. Tubeless tire removal, repair, and remounting procedures belong to Honda’s separate Tubeless Tire Manual and are not reproduced here.
