2008 Harley-Davidson Softail FLST, FLSTC, FLSTF, FLSTN, FLSTSB, FXCW, FXCWC, FXST, FXSTB & FXSTC Service Manual (P/N 99482-08A)

• Official Harley-Davidson OEM publication 99482-08A in a 629-page PDF, covering 2008 FLST, FLSTC, FLSTF, FLSTN, FLSTSB, FXST, FXSTB, FXSTC, FXCW, and FXCWC Softail models.
• Engine repair coverage includes compression and cylinder-leakdown testing, engine removal and installation, top- and bottom-end overhaul, cylinder-head and valve-seat work, cam support plate and oil-pump service, and counterbalancer timing and assembly.
• Chassis procedures address sealed wheel bearings, laced-wheel assembly and truing, cast-wheel runout, vehicle alignment, brake master cylinders and calipers, brake bleeding, steering-head service, and both telescopic and Springer front forks.
• Primary-drive and transmission sections detail clutch-pack service, primary chaincase work, drive-belt and sprocket replacement, transmission removal and internal disassembly, shifter setup, and main-drive-gear bearing and seal repair.
• Fuel-system content covers the induction module, injectors, fuel pump and regulator, fuel-pressure and intake-leak testing, model-specific exhaust layouts, California evaporative-emissions hardware, and HDI active-intake and active-exhaust equipment.
• Electrical coverage includes starter bench testing and overhaul, charging and ignition components, TSM/TSSM/HFSM hardware, handlebar-switch repair, connector and terminal service, connector-location data, and model-specific wiring diagrams.
• Dedicated reference sections collect special-tool part numbers, component-specific torque tables, service wear limits, capacities, adjustment data, electrical test specifications, connector procedures, and metric, fluid, and torque conversions.

2008 Softail Model and Engine Coverage

This factory service manual is built around the balanced, air-cooled, fuel-injected 1,584 cc Twin Cam 96B used in the covered 2008 Softail lineup. Its VIN tables map the individual model codes and identify the Brazil-only FLST Heritage Softail along with FLSTC and FLSTF Shrine applications. The book also separates work where the hardware differs, including FLSTSB Springer steering and brake components, FXCW/FXCWC body and electrical layouts, California emissions equipment, and international-market systems.

Harley-Davidson describes the manual as supporting basic maintenance and repair while presenting factory-approved major repair methods to professional technicians. It is therefore suited to experienced owners performing routine service and to technicians with the presses, precision measuring equipment, diagnostic access, and special tools required for internal engine, transmission, brake, and chassis work.

Maintenance, Twin Cam 96B, and Transmission Repair

The maintenance chapter provides the regular-service schedule and quick-reference chart, then carries the work into brake-pad and disc inspection, battery care, belt deflection, clutch and throttle-cable adjustment, steering-head fall-away, suspension setup, front-fork oil service, critical fastener checks, and symptom-based troubleshooting.

Internal engine coverage reaches the oil-flow and breather systems, oil-pressure testing, valve-train noise diagnosis, and smoking or oil-consumption checks. Factory overhaul content addresses valve-guide replacement and seat refacing, cylinder deglazing or boring, piston and ring inspection, camshaft and hydraulic-tensioner service, crankcase bearing work, and balance-shaft chain alignment. The transmission material explains power flow through all gears and covers inspection and repair of the mainshaft, countershaft, shift drum, forks, side-door bearings, main drive gear, and transmission case.

Wiring Scope, Diagrams, and Factory Tooling

Appendix B supplies color-coded domestic and international wiring coverage, including a dedicated FXCWC diagram set. Named diagrams and views include Engine Oil Flow: Top End, Camshaft Timing Marks, Transmission Power Flow, the CA Evaporative Emissions Control System schematic, the non-FXCWC Starting and Charging Circuits, and the dedicated FXCWC Main Harness.

This volume directs full EFI troubleshooting, ECM and sensor function testing, starter-circuit diagnosis, and security-module password learning or fob assignment to the separate model-year Electrical Diagnostic Manual. It does cover component removal and installation, fuel-pressure and intake-leak tests, starter component tests, electrical specifications, connector repair, and the wiring diagrams. Idle speed setting specifically requires Digital Technician HD-44750, which the manual identifies as dealer-only equipment.

The tool index ties each factory tool to its procedure. Examples include fuel-pressure gauge HD-41182 with adapter HD-44061, balance-shaft retention pins HD-44062, balance-shaft sprocket alignment tool HD-48615, and main-drive-gear bearing and seal installation tool HD-47932.

The manual warns that rotating the engine from a cam-sprocket flange bolt can break the bolt head and damage the flywheel or camshaft. Removing or installing the front master cylinder without the specified lever insert can damage the stoplight-switch boot and plunger. Fuel-system, hydraulic-brake, wheel, fork, and internal powertrain work should be undertaken only with the motorcycle securely supported and with the equipment and experience needed to follow the factory safety warnings.
