2006 Harley-Davidson Softail FLST and FXST Factory Service Manual Set (P/N 99482-06)

This 2006 Harley-Davidson Softail FLST/FXST factory service manual set combines the Softail Models Service Manual (P/N 99482-06), Electrical Diagnostics (P/N 99498-06), and FLSTFSE2 Service Supplement (P/N 99494-06). It covers carbureted and EFI models, with additional procedures for the FLSTFSE2.

• Maintenance: Service schedules, engine oil and filter changes, primary-chaincase and transmission lubrication, battery care, brake-pad wear limits, and suspension inspections.

• Engine repair: Twin Cam 88B removal, top- and bottom-end overhaul, cylinder-head service, cam-support-plate work, counterbalancer repair, and oil-system inspection.

• Drive and transmission: Primary-chain tensioner service, clutch repair, drive-belt replacement, and gearbox disassembly, inspection, and reassembly.

• Chassis: Wheel lacing and truing, steering-head bearing adjustment, Springer fork service, brake-caliper repair, and brake bleeding.

• Fuel systems: Constant velocity (CV) carburetor service, intake-leak testing, and EFI fuel-pressure, injector, idle air control, and sensor procedures.

• Electrical diagnostics: Starting and charging tests, ignition-coil checks, TSM/TSSM troubleshooting, diagnostic flowcharts, wiring diagrams, and connector views.

• FLSTFSE2: Hydraulic-clutch bleeding, secondary clutch actuator rebuilding, engine-component differences, and tachometer fault tracing.

This set suits mechanically qualified owners and technicians familiar with engine disassembly and electrical testing; advanced diagnosis requires the specified meters, adapters, or diagnostic equipment.

Scheduled Maintenance and Springer Chassis Service

Maintenance charts cover 5,000, 10,000, 15,000, 20,000, and 25,000-mile service intervals, with separate first-service requirements for Springer and hydraulic-fork models. Shop-practice sections address cleaning, assembly, hardware inspection, and thread repair.

FLSTSC and FXSTS steering-head procedures distinguish their different balance points and fall-away checks. The Drive Belt Wear Patterns illustrations and accompanying analysis chart help assess belt damage before deciding whether replacement is required.

Engine Overhaul, Primary Drive, and Transmission

Cylinder-head work extends to valve guides and seats, while the engine sections cover piston inspection, crankcase service, and counterbalancer bearings. Engine Oil Flow: Cam Support Plate/Right Crankcase Half traces the lubrication passages used in the oil-system explanations.

Cam-support-plate procedures warn that uncontrolled tensioner release can stretch the spring or crack the tensioner shoe. The primary-drive section identifies the clutch hub mainshaft nut's left-hand threads and cautions against methods that damage the hub or threads.

Special-tool references include cam chain tensioner unloader HD-42313 and primary drive locking tool HD-41214. Appendix D provides separate mainshaft and countershaft overhaul procedures for Japanese-market transmissions.

CV Carburetor and EFI Troubleshooting

Carburetor coverage includes vacuum-piston operation, float-level adjustment, and inlet-valve replacement. EFI procedures address the fuel pump, induction module, manifold absolute pressure (MAP) sensor, and idle air control.

The Fuel System Electrical Test charts separate pump-circuit faults from other starting problems. Fuel-pressure testing and intake-leak checks provide further diagnostic paths for poor running.

Fuel-system and electrical work involves pressurized gasoline and accidental-start hazards; follow the manual's battery-disconnection and fuel-pressure-relief precautions.

Starting Circuits, Fault Codes, and TSSM

Separate Starting Circuit: Carbureted Models and Starting Circuit: EFI Models diagrams support the corresponding diagnostic routines. Fault-code sections cover vehicle speed sensors, ignition coils, module communication, and Turn Signal Security Module (TSSM) faults, including password learning after relevant module replacement.

EFI breakout-box testing uses HD-43876 with a DVOM. Digital Technician HD-44750 is specified for functions such as distinguishing current from historic codes and adjusting warm EFI idle speed; speedometer self-diagnostics provide a separate route for reading and clearing codes.

FLSTFSE2 Hydraulic Clutch and Engine Differences

The supplement details its distinct cylinder-head components and counterbalancer bearing arrangement. Hydraulic-clutch coverage extends to master-cylinder rebuilding, fluid-line bleeding, and release-plate movement checks; the Tachometer Circuit diagram supports the supplement's instrument diagnostics.

Its EFI section directs service and electrical troubleshooting to the other included publications. The supplement's chassis and drive tables give conflicting primary-chaincase capacities, so that specification needs clarification before use.

Selected Torques for Mounts, Drains, and Spark Plugs

These examples are a small sample of the torque data in the main Softail service manual.

Front engine mounting nuts are listed at 70–80 ft-lbs (94.9–108.5 Nm). The transmission drain plug specification is 14–21 ft-lbs (19.0–28.5 Nm).

Spark-plug installation is specified at 12–18 ft-lbs (16.3–24.4 Nm), with the anti-seize thread preparation described in the procedure.

Searchable PDF, Bookmarks, and Publication Breakdown

Text search and diagram detail: Searchable text and embedded bookmarks cover the service, diagnostics, and supplement sections. Small connector numbers and wire-color codes on the wide harness diagrams require zooming for comfortable reading.
