Harley-Davidson Touring 2008 Service Manual Set (P/N 99483-08)

The base manual carries the procedures shared across the regular Touring range, while the two service supplements add the hardware and systems unique to the Police and FLHTCUSE3 builds. The Electrical Diagnostics Manual supplies circuit testing and fault-isolation procedures to use alongside the mechanical repair information.

The supplements are companion publications rather than stand-alone replacements for the main manual. The CVO engine chapter covers Twin Cam 110 engines; Japan-market models equipped with Twin Cam 96 engines use the base manual's engine specifications and service procedures.

Searchable PDFs, Bookmarks and Wiring Detail

Text search and diagram detail: All four manuals contain searchable text and embedded PDF bookmarks. The separate contents index has no bookmarks. Dense wiring diagrams require zooming to read small wire-color codes, connector identifiers and pin numbers.

The ZIP contains five printable PDFs totaling 1,879 pages: the four publications listed above plus a separate one-page contents index. Covers, preliminary matter, notes pages, appendices and diagram title/reverse pages are already included in the manual page counts.

Twin Cam Repair, Touring Chassis and Electrical Diagnosis

This selected content overview highlights the main workshop areas rather than reproducing the complete contents. Other topics include storage preparation and garage-door-opener service.

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

• Primary drive and transmission: Clutch repair, compensator and sprocket service, drive-belt replacement, transmission removal, internal disassembly, inspection, reassembly and adjustment.

• Chassis and brakes: Wheel bearings, laced-wheel truing, vehicle alignment, forks, rear suspension, steering-head bearings, master cylinders, calipers, brake bleeding and ABS component service.

• Fuel injection and throttle control: Fuel-pump, regulator, injector and induction-module service, fuel-pressure and intake-leak tests, twist-grip-sensor and throttle-control-actuator procedures.

• Electrical troubleshooting: Starting and charging tests, instrument and serial-data diagnosis, TSM/HFSM security, EFI fault charts, advanced audio, ABS diagnostics and connector repair.

• Police and CVO equipment: Police air-seat and pursuit-system service, plus CVO hydraulic-clutch, heated-accessory, audio, navigation and power-lock procedures with dedicated wiring diagrams.

These publications address basic maintenance and repair as well as professional Harley-Davidson service methods; major repairs and diagnostic work require the specified tools, test equipment and relevant mechanical experience.

Maintenance, Chassis and Bodywork

Routine service goes beyond oil changes. The maintenance chapter addresses lubricant service, clutch adjustment, rear-belt inspection and setting, battery care, suspension checks, spark plugs, headlamp alignment, engine mounts and critical fasteners.

Model-specific procedures distinguish the FLHX rear-belt setup. Separate bodywork sections cover fairings, windshields, nacelles, saddlebags and Tour-Pak assemblies for the FLHR/FLHRC, FLHT-family, FLHX and FLTR configurations.

ABS wheel bearings: The manual distinguishes encoder bearings from standard bearings and specifies their orientation on the primary brake-disc side. Magnetic parts trays and magnetic-base indicators can damage the encoder bearings and wheel-speed sensors.

Engine Overhaul and Drivetrain Service

The Twin Cam material follows oil flow and pressure diagnosis through engine removal, complete top-end and bottom-end repair, and subassembly service. It covers rocker supports, pushrods and lifters, valves, cylinders, pistons and rings, camshafts, chain tensioners, crankcases and flywheel assemblies.

Cam and piston identification: Front and rear camshafts and their spacers must remain correctly identified, with timing marks aligned during assembly. The piston sections distinguish the later tapered wrist-pin boss and connecting-rod design from earlier components.

The flywheel and connecting-rod section provides inspection and assembly-replacement criteria; it calls for replacement of the complete flywheel assembly when its specified constituent parts require replacement.

Primary-drive and transmission sections extend to clutch-pack inspection, shifter and clutch-release work, internal gearbox service and operational checks. Torque tables, wear limits, runout specifications and clearance data accompany the procedures.

Police and FLHTCUSE3 Supplement Details

Police equipment: The supplement covers the air-suspension seat and reservoir, saddlebag hardware, FLHP/FLHPE tachometer bracket, oil cooler and thermostat adapter, automatic compression release, horn/siren-yelp and pursuit switches, rear marker lamps and police wiring.

Its fuel-system, starter, drive and transmission chapters refer back to the main manual rather than repeating shared procedures. Keeping both publications available lets the technician combine Police-specific information with the corresponding base repair instructions.

FLHTCUSE3 equipment: Additional material covers the hydraulic clutch and secondary actuator, engine wear limits, cylinder boring and honing, oil-cooler hardware, handlebars, heated handgrips and heated seat.

GPS, XM radio, radio software updates, the advanced-audio amplifier, power locks, automatic compression release, TGS/ECM reset and HFSM components receive dedicated treatment. The cylinder-machining section warns that an incorrect honing finish can cause inadequate oil retention, piston seizure or excessive oil consumption.

Fault Charts, Wiring and Required Equipment

The Electrical Diagnostics Manual separates starter no-click, slow-crank and engagement faults from voltage-drop and charging problems. EFI charts address no-start, start-then-stall, misfire, fuel-pressure, intake-leak, sensor, injector, ignition and electronic-throttle faults.

Security, turn-signal, radio and speaker diagnostics accompany ABS initialization, indicator, wheel-speed-sensor, pump and module fault charts. A separate appendix addresses TSM/TSSM systems for Japan and Korea.

Representative diagrams include the Starting Circuit for FLHR/C/S, the Starting Circuit for FLHX, FLHT/C/U and FLTR, the EFI Circuit, the TGS/TPS Control Circuit, the Brake Control Circuit With ABS and the Police Optional Strobe System. CVO diagrams cover lighting, starting/charging, XM/CB audio, heated accessories, automatic compression release and power locks.

Tool references include the HD-35381A Belt Tension Gauge, HD-44060B Wheel Bearing Remover/Installer and HD-46247A Vehicle Alignment Tool. Diagnostic procedures call out the HD-48637 EFI Breakout Box, HD-48642 ABS Breakout Box and HD-44750 Digital Technician; the base manual specifies HD-48650 Digital Technician II for the ABS service procedure after certain brake-system repairs.

A fully dressed Touring motorcycle is a heavy load, and brake, ABS, fuel, electrical and engine-removal work can create serious hazards. Secure the motorcycle on a correctly rated lift, follow the publication's torque sequences and bleed or initialization routines, and use the specified test equipment before returning the machine to service.

A Preview of Oil- and Fuel-Pressure Test Data

The base manual's oil-pressure check specifies 30–38 psi at 2,000 rpm with engine oil at normal operating temperature, 230°F (110°C). The surrounding material covers oil circulation and possible causes of a persistent oil-pressure warning.

Its running-engine fuel-pressure test specifies a steady 55–62 psi as engine speed changes. Results outside that range lead into the companion Electrical Diagnostics Manual's fuel-system fault-isolation procedures.
