2008 Harley-Davidson Touring, Electra, Glide, Road King, Sportster Service Manual (P/N 99483-08)

• Covers the 2008 Harley-Davidson Touring line, including FLHR/FLHRC Road King, FLHT/FLHTC/FLHTCU Electra Glide, FLHX Street Glide, and FLTR Road Glide models, along with Shrine and factory sidecar variants.
• Extends the base coverage to FLHP, FLHPE, and FLHTP Police models with the Twin Cam 103, plus FLHTCUSE3 Screamin' Eagle Ultra Classic and Japan-market FLHTCU3-CVO configurations identified by the supplement's Twin Cam 110 and Twin Cam 96 engine codes.
• Contains four Harley-Davidson factory publications totaling 1,878 PDF pages: Service Manual P/N 99483-08, Electrical Diagnostics Manual P/N 99497-08, Police Supplement P/N 99483-08SP, and FLHTCUSE3 Supplement P/N 99500-08, plus a one-page contents index.
• Covers engine removal and installation, Twin Cam top- and bottom-end overhaul, cylinder-head and piston service, cam-support-plate and oil-pump work, primary-drive and clutch repair, transmission removal, internal disassembly, reassembly, and final adjustment.
• Details front and rear wheel service, sealed and ABS encoder bearings, laced-wheel truing, vehicle alignment, fork and rear-suspension repair, steering-head service, brake master cylinders and calipers, brake bleeding, pad and disc replacement, and ABS component service.
• Adds DTC-based troubleshooting for starting and charging, instruments, EFI and electronic throttle control, TSM/HFSM security, advanced audio, and ABS, supported by connector repair information, circuit diagrams, wiring schematics, and diagnostic flowcharts.

System Coverage and Workshop Utility

The base manual carries the procedures shared across the regular Touring range, while the two service supplements add only the hardware and systems unique to the Police and FLHTCUSE3 builds. That division matters in the shop: the Police supplement does not duplicate the fuel-system, starter, drive, or transmission chapters, so those repairs are performed from the corresponding sections of P/N 99483-08. The supplements are companion publications rather than stand-alone replacements for the main manual.

Routine service coverage goes well beyond oil changes. The maintenance chapter addresses engine oil and filter service, primary-chaincase and transmission lubricant, clutch adjustment, rear-belt inspection and setting, brake bleeding, brake-pad and disc inspection, battery care, suspension checks, steering-head bearings, spark plugs, headlamp alignment, engine mounts, and critical fasteners. Model-specific procedures distinguish the FLHX rear-belt setup and separate bodywork, fairing, windshield, nacelle, saddlebag, and Tour-Pak repair sections for FLHR/FLHRC, FLHT-family, FLHX, and FLTR configurations.

The Twin Cam engine material follows oil flow and pressure diagnosis through engine removal, complete top-end and bottom-end repair, and subassembly service. Covered work includes rocker supports, pushrods and lifters, cylinder heads and valves, cylinders, pistons and rings, camshafts and chain tensioners, the cam support plate, oil pump, crankcase, flywheel assembly, and related inspection limits. Primary-drive, clutch, compensator, drive-belt, sprocket, shifter, clutch-release, and transmission sections document removal, disassembly, inspection, reassembly, installation, and operational checks.

Police-specific chapters cover the air-suspension seat and reservoir, police 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. The FLHTCUSE3 supplement adds the hydraulic clutch and secondary actuator, CVO engine wear limits and machining data, oil-cooler hardware, handlebar and heated-handgrip service, heated seat, GPS, XM radio, software update procedures, advanced-audio amplifier, power locks, automatic compression release, twist-grip-sensor reset, and HFSM components.

Technical Data Highlights

P/N 99497-08 supplies the diagnostic depth normally missing from a mechanical service manual. Its flowcharts isolate starter no-click, slow-crank, and engagement faults; voltage-drop and charging-system problems; instrument and serial-data faults; TSM/HFSM security and turn-signal issues; EFI no-start, start-then-stall, misfire, fuel-pressure, intake-leak, sensor, injector, ignition, and electronic-throttle faults; radio and speaker DTCs; and ABS initialization, indicator, wheel-speed-sensor, pump, and module faults.

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. The CVO supplement also supplies dedicated lighting, starting/charging, XM/CB audio, heated-accessory, automatic-compression-release, and power-lock circuits.

Tool references identify the equipment called out by the procedures, such as the HD-35381A Belt Tension Gauge, HD-44060B Wheel Bearing Remover/Installer, HD-46247A Vehicle Alignment Tool, HD-48637 EFI Breakout Box, HD-48642 ABS Breakout Box, and HD-44750 Digital Technician. Reference sections consolidate model-specific torque tables, fluid capacities, service wear limits, runout and clearance specifications, pressure tests, voltage and resistance checks, connector pin information, and DTC charts.

Several repair traps are addressed directly. ABS encoder bearings can be damaged by magnetic parts trays or magnetic-base indicators and must remain on the primary brake-disc side in the specified orientation. Front and rear camshafts and their spacers are not interchangeable; incorrect identification or timing-mark alignment can leave the cam drive assembled out of time. The top-end chapters also warn against mixing the 2007-and-later tapered wrist-pin piston and connecting-rod design with earlier components.

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.
