Harley-Davidson Touring FLT 2003 Service & Diagnostics Manual Set (P/N 99483-03A)

Use the mechanical procedures alongside the electrical test charts when a repair involves both component service and circuit diagnosis. The FLHRSEI2 supplement supplies the model-specific differences and refers shared procedures back to the base Touring manual.

Police VIN codes and shared Touring wiring information are present, but the separate police service supplement is not included. Parts ordering is referred to the appropriate parts catalog, which is also separate from this set.

Searchable PDF and Wiring Detail

Text search, bookmarks, and diagrams: Searchable text and embedded bookmarks cover all three publications. The “KEYWORD SEARCH” bookmark is inactive. Dense main-harness and lighting diagrams require zooming to read small pin numbers and wire-color codes.

One printable PDF contains 1,193 pages, including one shared title/contents page and 23 blank pages. The blank pages are already included in the publication counts above.

Engine Overhaul, Touring Chassis, and Electrical Fault Tracing

The following is a selected content preview, rather than a complete table of contents. Other documented topics include scheduled maintenance and electrical connector servicing.

• Engine repair: Step-by-step engine removal and installation, top- and bottom-end overhaul, cylinder-head and piston service, cam support plate and oil-pump repair, and crankcase work.

• Chassis and brakes: Wheel-bearing service, laced-wheel truing, vehicle alignment, master-cylinder and caliper repair, brake bleeding, fork and steering-head work, rear air suspension, and swingarm service.

• Drive and transmission: Primary-chain and clutch repair, belt and sprocket service, and transmission teardown covering the shifter cam, forks, shafts, main drive gear, case, and oil pan.

• Fuel systems: Carburetor and EFI component service, trouble-code retrieval, no-start and misfire fault isolation, fuel-system electrical checks, and fuel-pressure testing.

• Electrical diagnosis: Starting and charging tests, battery-load testing, instrument and speedometer checks, TSM/TSSM setup, security faults, and model-specific wiring diagrams.

• Sound and cruise control: Premium Sound, radio, CB, intercom, headset, and speaker troubleshooting, plus cruise-control diagnostic charts.

• FLHRSEI2 differences: Model-specific engine, hydraulic-clutch and secondary-actuator service, with chassis, trim, instrument, and electrical service information.

Its deeper overhaul and electrical sections assume press work, DVOM testing, dedicated fixtures, and Harley-Davidson diagnostic equipment, making the set best suited to professional technicians and experienced mechanics. The maintenance chapters are more approachable, but the major repair work is not beginner-level material.

Twin Cam Overhaul and Driveline Service

The mechanical volume supplies component-specific torque tables, manufacturing tolerances, wear limits, fluid specifications, adjustment data, and final checks alongside the repair procedures.

Flywheel/connecting-rod coverage includes removal, inspection, and installation. Connecting-rod service is limited to upper-bushing replacement; damaged rods or lower-bearing problems call for replacement of the flywheel assembly.

Camshaft and cam-bearing procedures reference the HD-43644 remover/installer. Chassis alignment work uses the HD-46247 vehicle alignment tool. The rear air-shock section covers removal and replacement; the shocks themselves are not repairable.

Carburetor and EFI Service

The carbureted sections address the enrichener, carburetor, vacuum-operated fuel valve, and evaporative-emissions hardware. EFI service covers the injected fuel tank, electrical bracket, sensors, and induction module.

The diagnostic charts connect symptoms and trouble codes with circuit checks and component tests. Fuel-pressure diagnosis distinguishes pressure loss and restricted fuel flow from faults that can initially resemble ignition trouble, supporting repair decisions beyond a generic symptom list.

Security, Starting, and Accessory Diagnostics

TSM/TSSM coverage includes vehicle-delivery setup, password learning, current and historic trouble codes, breakout-box checks, and post-repair verification.

Tool references include the HD-41325 Scanalyzer with HD-41325-95C cartridge, the HD-42682 carbureted/TSM-TSSM breakout box, and the HD-43876 EFI breakout box. Sound-system testing uses the HD-44608 radio breakout box.

The starter chapter also contains disassembly, testing, repair, and assembly procedures, including armature, field-winding, and brush-holder checks.

Mechanical Views and Model-Specific Wiring

Mechanical illustrations include the Engine Oil Flow - Cam Support Plate/Right Crankcase Half view, the Cylinder Head/Cylinder/Piston Assemblies exploded view, and the Transmission Power Flow Schematic.

Electrical references include the EFI System Circuit, Starter/TSSM Circuit, and TLE/TLE Ultra Sidecar Audio Harness diagrams. Main, engine-management, starting/charging, lighting, and sound sheets distinguish FLHT/FLHTC/FLHTCU, FLTR, FLHR/FLHRC, and sidecar configurations.

FLHRSEI2 Engine and Hydraulic-Clutch Differences

The supplement provides different cylinder-head and piston data, cam timing marks, flywheel service information, and oil-cooler and thermostat procedures. It also documents sprocket-shaft bearing inner-race replacement.

Its hydraulic clutch uses a secondary actuator, so the base manual’s cable-clutch procedures do not describe that hardware. Shared fuel-injection service remains in the Touring manual, while system diagnosis and electrical troubleshooting are handled by the diagnostic volume.

Repair Cautions

The engine chapter warns that movement or loss of the lifter anti-rotation pin can allow lifter rotation and severe engine damage. The primary-chaincase section warns that unprotected mainshaft splines can damage the lip seal during assembly.

Engine removal, raised-motorcycle work, brake and fuel-system service, and battery testing require secure support, proper isolation or pressure control, and normal workshop safety practices.

Oil-Pressure and EFI Test-Specification Preview

The base Touring engine specifications list oil pressure of 30–38 psi at 2,000 rpm and a normal operating temperature of 230°F (110°C), alongside lubrication-system information and oil-flow diagrams.

EFI fuel-pressure testing specifies 55–62 psi (380–425 kPa), remaining steady as engine speed changes. The accompanying diagnostic chart addresses pressure loss, restricted delivery, and regulator-related faults.
