1970–1972 Harley-Davidson Electra-Glide/Super Glide Service Manual (P/N 99482-72)

Factory service coverage for 1970-1972 Electra-Glide and Super Glide motorcycles, supplied as a 183-page PDF of Harley-Davidson Part No. 99482-72. The publication is copyrighted 1971, and the service pages carry the revision date 10-71. Its mix of basic maintenance information and factory-approved major repair methods suits experienced owners for routine service and professional mechanics for internal engine, transmission, brake, and electrical work requiring precision measuring equipment and special tools.

• Chassis procedures cover front and rear drive-chain adjustment, chain and sprocket replacement, wheel and hub service, wheel spoking and truing, wheel alignment, handlebar controls, frame dimensions, rear-fork inspection, and shock-absorber service. Separate Electra-Glide and Super Glide front-fork sections include oil changes, inspection, disassembly, bushing repair, reassembly, and alignment work.
• Brake coverage distinguishes Electra-Glide and Super Glide mechanical front drum assemblies from the 1972-and-later Electra-Glide front disc brake. It also covers rear and sidecar wheel brakes, front and rear master cylinders, caliper service, brake adjustment, and hydraulic-system bleeding.
• Engine repair runs from removal and stripping through cylinder-head, rocker-arm, valve, guide, cylinder, piston, ring, connecting-rod bushing, oil-pump, tappet, timing-gear, flywheel, bearing, and crankcase work. Related chapters supply torque data, clearances, wear limits, fitting specifications, and oil-pressure checks.
• Fuel-system sections document the factory changeover from the Tillotson Model HD carburetor used on 1970 models to the Bendix Model 16P12 unit for 1971 and later models. Each system receives its own operating description, adjustment information, inspection procedures, disassembly, cleaning, repair, reassembly, and exploded view; the Tillotson chapter adds leakage tests and a symptom-based troubleshooting section.
• Transmission and starting-system work includes clutch adjustment and overhaul, electric-start drive service, shift-linkage adjustment, hand-shift and foot-shift covers, shifter forks, main-drive-gear oil-seal replacement, and complete four-speed gearbox disassembly, inspection, and reassembly. A separate procedure explains the component differences for the three-speed-and-reverse transmission.
• Electrical diagnosis includes dedicated wiring diagrams for the 1970 Electra Glide, 1971 Electra Glide, 1971 Super Glide, and 1972 Electra Glide. The chapter also covers switches, headlamp aiming, alternator and rectifier-regulator testing, circuit-breaker troubleshooting, ignition timing, coil and spark-plug checks, battery service, horn testing, and starter-motor repair.

Model and Configuration Detail

The specification tables identify FLP, FLH, and FX applications and separate solo, sidecar, four-speed, and three-speed-and-reverse gearing where the factory data differs. Maintenance charts cover predelivery, break-in, regular service, lubrication points, approved lubricant categories, and fault-finding for engine starting and running, lubrication, carburetion, electrical, transmission, clutch, and brake complaints. The chassis section also contains factory fiberglass body repair coverage for gel-coat touch-up, molded-color surface repair, holes, punctures, and structural breaks.

Factory Tools and Technical Illustrations

This is workshop-level material, with named service equipment rather than generic tool references. Examples include the Fork Stem and Bracket Aligning Gauge, Part No. 96245-51, Carburetor Leakage Tester, Part No. 94750-68, Crankcase Main Bearing Lap, Part No. 96710-40, and Main Drive Gear Oil Seal Tool, Part No. 95660-42. The oil-seal tool is specifically covered for seal replacement without a full gearbox teardown.

Useful visual references include the Frame with Basic Dimensions, Sprocket Shaft Bearing Assembly - Section View, Model HD Carburetor - Exploded View, Bendix Carburetor - Exploded View, Mainshaft Assembly - Exploded View, and Charging System - Schematic Diagram. Model-specific wiring sheets are paired with diagram keys, while component illustrations identify assembly order and individual service parts throughout the chassis, engine, transmission, and electrical sections.

Repair Cautions and Safety

The carburetor chapter warns that drilling beyond the Tillotson main-nozzle welch plug can damage the nozzle assembly, and that wires or drills can burr or resize calibrated passages. The charging-system section likewise cautions against connecting or disconnecting the stator-to-module plug with the engine running because the rectifier-regulator module can be damaged.

Fuel-tank repair carries a specific fire and explosion warning if all fuel and vapor have not been purged before flame work. Fork, wheel, brake, engine, and transmission procedures also involve heavy assemblies and safety-critical systems; the motorcycle should be securely supported, and the specified measuring and torque equipment should be used for major repair work.
