1959–1969 Harley-Davidson Electra Glide, Duo-Glide Service & Repair Manual (P/N 99482-69)

• Covers 1959-1969 Harley-Davidson Duo-Glide and Electra Glide motorcycles, identified in the factory specifications by the FL and FLH model letters. This is a 240-page PDF of Harley-Davidson Service Manual Part No. 99482-69, reprinted in October 1971.
• Chassis repair coverage runs from front (primary) and rear-chain service through wheel-hub overhaul, spoke replacement, wheel truing and alignment, Hydra-Glide fork work, steering-head bearings, rear-fork and shock-absorber service, seat-post suspension, brake repair, hydraulic bleeding, and fiberglass body repair.
• Engine repair sections cover removal preparation, cylinder heads, valve guides and seats, cylinders, pistons and rings, connecting rods, the oil pump and breather system, timing gears, gearcase bushings, crankcases, flywheels, and main-bearing fitting and assembly.
• Fuel-system and drivetrain chapters address Model HD, M, and DC carburetor operation and service, fuel strainers, air cleaners, tanks and supply valves, plus clutch adjustment and teardown, kick and electric starter drives, hand- and foot-shift controls, shifter timing, mainshafts, countershafts, and gearbox repair.
• Electrical diagnosis is organized by production period, with keyed wiring diagrams for the 1959, 1960, and 1961-1964 Duo-Glide and the 1965-1967 and 1968-1969 Electra Glide, followed by generator, circuit-breaker, ignition, regulator, battery, horn, lighting, solenoid, and starter-motor tests.
• Factory reference material includes service-interval and lubrication charts, exploded assembly and section views, component-specific torque and clearance data, bearing and bushing fits, fluid capacities, carburetor settings, ignition-timing information, electrical test specifications, and illustrated special-tool listings with factory numbers.

Coverage and Year Breaks

The publication states that its maintenance and repair information applies to 1959 through 1969 Duo-Glide and Electra Glide models. It also separates several important running changes instead of treating the full decade as one build. Examples include 1966-and-earlier versus 1967-and-later wheel hubs, 1965-and-earlier versus 1966-and-later cylinder heads, early and later rear shock absorbers, the 1968-and-later oil pump, and a 1969 crankcase bearing-lock-ring detail. These distinctions matter when selecting parts, tools, and the correct repair procedure.

Some shared-component pages also carry Sportster or Servi-Car headings, particularly in the carburetor, generator, regulator, horn, and starter-motor material. The stated vehicle coverage remains the Duo-Glide and Electra Glide FL/FLH line; this is not a complete Sportster or Servi-Car service manual.

Factory Repair Depth

The chassis material goes beyond routine adjustment. It documents wheel-hub disassembly, bearing service, sprocket replacement and riveting, spoke lacing, rim truing, tire runout checks, frame-dimension checks, fork-slider rebushing, fork-tube and bracket alignment, rear-shock disassembly, brake-drum refinishing, and hydraulic brake bleeding. The seat section explains the spring-loaded seat post, while the fiberglass chapter covers surface finishing, touch-up, and structural patching of holes, punctures, and breaks.

The engine chapters move from stripping the motorcycle for engine repair through valve and seat work, cylinder refinishing, piston-ring fitting, connecting-rod alignment, oil-pump inspection, timing-gear installation, crankcase separation, flywheel truing, bearing-race lapping, and final assembly checks. Transmission coverage adds clutch removal, starter-clutch work, main-drive-gear oil-seal service, shifter-fork inspection, shifter-gauge adjustment, and internal gearbox assembly.

The manual also calls out failure-prone details. It warns that a reused or overexpanded piston-pin lock ring can release in service and ruin both the piston and cylinder. In the gearcase section, overtightening the oil-pump body can displace the plastic gaskets, remove gear side clearance, and seize the pump. For wheel, fork, rear-shock, engine, or transmission repair, the motorcycle should be secured on a stable stand and spring-loaded or hydraulic components controlled before disassembly.

Illustrations, Test Data, and Tools

Useful illustrations include the Lubrication and Service Chart, Electra-Glide Lubrication System, 1963 to 1965 Oil Feed Pressure System, Hydra-Glide Fork - Exploded View, Model M Carburetor - Exploded View, and 1968-1969 Electra-Glide Wiring Diagram. The electrical chapters distinguish standard and fan-cooled generators and cover Delco-Remy two-pole and four-pole as well as Prestolite four-pole starter motors.

Separate tool sections identify equipment for chassis, engine, transmission, and electrical work. Examples include the 96219-50 frame-head bearing adjusting cone and locknut wrench, 96254-50 fork-slider bushing tools for the Hydra-Glide fork, 97010-52A rear-shock absorber tool, and 96295-65 timing-mark view plug. These listings show where normal hand tools end and factory fixtures, reamers, pullers, gauges, or holding tools are expected.
