Harley-Davidson VRSC/VRSCR 2006 Service Manual Set (P/N 99501-06A)

The service manuals cover mechanical repair and component replacement, while the diagnostic volumes provide circuit testing and fault-code troubleshooting. The VRSCSE2 supplement supplies model-specific information and is used with the VRSC service manual.

PDF Files, Search, and Navigation

Finding procedures and wiring: The PDFs contain searchable text. Embedded bookmarks are available in the content files; the separate chapter-contents PDFs have no bookmarks. Small wiring labels and connector-pin numbers require zooming in the checked diagrams.

The ZIP contains 97 printable PDFs totaling 1,968 pages, split into sections, appendices, and contents files. This total includes 2 master contents pages, 38 blank or page-number-only pages, 35 notes pages, and 49 heading-only continuation pages. The original VRSCR documents overlap with the revised VRSC volumes.

Engine, Chassis, and Electrical Service Coverage

These selected topics show the range of work covered. Additional subjects include airbox and radiator-cover removal, headlamp alignment, and critical-fastener checks.

• Scheduled maintenance: Valve-lash inspection and shim adjustment, cam-timing verification, secondary cam-chain measurement, drive-belt service, hydraulic bleeding, steering-head fall-away, and suspension settings.

• Internal engine repair: Compression and leakage testing, oil-pressure diagnosis, cylinder-head service, crankcase disassembly, crankshaft and cylinder-liner work, oil-pump service, and cam installation.

• Chassis and brakes: Engine removal and replacement, engine mounts, frame rails, brake controls and calipers, wheel bearings, tire service, wheel alignment, and suspension repair.

• Clutch and transmission: Clutch removal and inspection, shift-shaft and seal replacement, drive-sprocket flange service, and input/output shaft disassembly and assembly.

• Fuel and cooling systems: Fuel pump/filter/sender service, injection-component replacement, fuel-pressure and intake-leak tests, cooling-system diagnosis, thermostat replacement, and water-pump service.

• Electrical troubleshooting: Starting and charging tests, instrument-module diagnostics, TSM/TSSM fault isolation, ECM checks, sensor testing, diagnostic flowcharts, and model-specific wiring diagrams.

• VRSCSE2 differences: Supplementary engine specifications, chassis procedures, instrument service, security-system diagnosis, and dedicated electrical troubleshooting for this configuration.

Suited to professional technicians, independent repair shops, and experienced owners equipped for precision measurement, electrical testing, and supported engine removal.

Valve Train and Internal Engine Work

The valve-train material covers lash measurement, shim selection and replacement, crankshaft positioning, cam-timing verification, and final inspection. Valve-lash and secondary cam-chain adjustments can be performed with the engine in the chassis; most other top-end repairs and bottom-end work require engine removal.

Step-by-step procedures extend to cylinder-head disassembly, crankcase separation, crankshaft and counterbalancer bearing replacement, and piston/cylinder-liner service. Torque tables, service wear limits, and valve-lash calculation worksheets support these operations.

The manual warns that rotating the engine in the wrong direction or with the secondary cam-chain tensioner removed can disturb timing and cause internal damage. Illustrations such as TDC Cam Timing Orientation and Cam, Tappet, Shim Orientation show the relevant component relationships.

Chassis, Hydraulic Controls, and Wheel Service

Coverage includes the steel perimeter frame and bolt-on lower rails, front and rear engine mounts, exhaust system, jiffy stand, footrests and foot controls, throttle cables, handlebars, and both wheels.

Hydraulic service addresses the clutch master cylinder and reservoir, hand lever, fluid line, secondary actuator, brake master cylinders, and calipers. Wheel procedures include sealed-bearing replacement, disc and rim runout checks, tire removal and installation, balancing, and alignment with engine centering. Later chassis sections also cover the front fork, steering head, fork lock, rear shocks, rear fork, seat, and fenders.

The engine stabilizer link is a horizontal locator, not a wheel-alignment adjustment; incorrect alteration can crack the crankcase mounting boss. Front brake-control procedures also identify how incorrect lever positioning can damage the stoplight-switch boot or plunger.

Secure the motorcycle on suitable lifting equipment and support the engine and frame as specified before engine-mount, removal, or wheel-alignment work. Electrical power, brake and clutch hydraulics, and the cooling system must be placed in the safe service condition described by the manual before related components are opened.

Fuel Injection and Cooling-System Diagnosis

Fuel-system procedures address the tank, pump, filters, sender, pressure regulator, injectors, and California evaporative-emissions components. Electronic fuel-injection coverage includes the ECM, throttle-position sensor, IAT and ECT sensors, idle air control, and MAP sensor.

Cooling-system material goes beyond routine coolant replacement to pressure-cap and system-pressure tests, leak diagnosis, thermostat and water-pump replacement, coolant pipes and hoses, radiator service, and oil-cooler work.

Electrical Fault Isolation and Wiring

The diagnostic volumes connect symptoms and fault codes to circuit diagrams, connector references, and test charts. Initial diagnostic checks and fault-code priorities help distinguish communication faults from the component codes they can trigger.

Coverage includes Scanalyzer and breakout-box use, starter and charging-system tests, instrument-module checks, TSM/TSSM diagnosis, password learning, and engine-management troubleshooting. Wiring examples include Main Harness, Ignition Circuit, Charging Circuit, and Security Circuit diagrams, with connector service for AMP Multilock, Deutsch, Mini-Deutsch, and Packard connections.

The VRSCSE2 supplement adds Screamin’ Eagle 1250 engine specifications and model-specific piston-pin, crankshaft, wheel, and clutch-actuator information. Its expanded electrical section covers the separate speedometer and tachometer, TSSM and EFI diagnosis, and dedicated main-harness and instrument/sub-harness diagrams.

Factory Tools and Service Illustrations

Factory references identify the HD-35381 Belt Tension Gauge, HD-45653 TDC Positioning Tool, HD-45306 Crankshaft Locking Pin, HD-45334 Secondary Cam Chain Measurement Tool, HD-45317 Engine Assembly Support Fixture, and HD-44060 Wheel Bearing Installer/Remover. These references help a shop determine equipment requirements before disassembly.

Supporting views include Steel Perimeter Frame and Bolt-on Lower Frame Rails (typical), Engine Strapped for Hoisting, HD-44060 Wheel Bearing Tools, and Wheel Alignment. Exploded drawings, routing illustrations, and fastener callouts accompany the written procedures.

Examples of Valve-Lash and Ignition Test Data

The VRSCR valve-lash tables specify an intake range of 0.195–0.245 mm and an exhaust range of 0.295–0.345 mm. The adjustment material pairs these limits with shim-selection tables and calculation worksheets.

For ignition diagnosis, the VRSCR electrical diagnostic volume gives a primary plug-top coil resistance test range of 0.3–0.5 ohms, alongside separate secondary-winding and coil-boot checks.
