Cataloging major assemblies into front cylinder head, rear cylinder head, primary drivetrain, secondary transmission, engine crankcase, and electrical circuits, the manual describes the vehicle, references engine and transmission systems, documents fuel system operation, and provides brake system procedures for the paired 1979 Sportster models.
Modular Topology
The document includes comprehensive cylinder head assembly procedures covering rocker arm installation, valve spring compression, and push rod positioning. Cylinder and piston sections detail ring fitting specifications, connecting rod alignment techniques, and piston pin bushing service methods. The crankcase subsystem references flywheel assembly truing, bearing fitting procedures, and main bearing specifications for proper engine foundation assembly.
Operational Framework
Carefully calling for gearcase components, the manual documents cam gear timing, oil pump disassembly, and valve tappet clearance adjustment. Crankshaft end play checking procedures are included, along with transmission mainshaft and countershaft group assembly. The fuel system section covers carburetor disassembly, float level adjustment, and accelerating pump maintenance documentation.
Diagnostic Standard
Carburetor troubleshooting procedures are documented for flooding, poor idling, hard starting, and power loss conditions. Brake system diagnostics reference pressure bleeding, rear brake pedal free play adjustment, and master cylinder servicing. Electrical system troubleshooting includes generator output checking, ignition timing procedures, and battery charge state evaluation methods.
Engineered Topology
Wiring diagrams are provided for both the XLH and XLCH models showing handlebar switch assemblies, lighting circuits, charging system connections, and ignition module integration. The transmission shifter mechanism documentation includes shifter fork selection, pawl carrier spring tension, and gear engagement clearance validation procedures.
Technical Standard
The manual documents torque specifications for fastener assembly across all major subsystems, including engine head bolts (65 ft-lbs), cylinder base nuts (25-30 ft-lbs), and transmission bearing installation procedures. Valve timing specifications are referenced for 79-85 degrees before top dead center intake opening, with exhaust opening at 81-89 degrees before bottom dead center. Fork oil capacity specifications (6 oz. for dry assembly, 5 oz. for wet assembly) and general torque requirements ensure proper joint function throughout the engine and drivetrain.
This 152-page factory service manual serves as the authoritative technical reference for 1979 Harley-Davidson XLH-1000 and XLCH-1000 Sportster models, featuring detailed procedural sections for all major maintenance, repair, and diagnostic operations.
