2005 Harley-Davidson Dyna FXD, FXDC, FXDL, FXDX, FXDWG Factory Service Manual with Electrical Diagnostics (P/N 99481-05)

The 2005 Harley-Davidson Dyna manuals cover FXD, FXDC, FXDL, FXDX and FXDWG models and their fuel-injected variants. The Service Manual (P/N 99481-05) is accompanied by the Electrical Diagnostic Manual (P/N 99496-05) for mechanical repair, maintenance and electrical fault tracing.

• Engine and lubrication: Twin Cam 88 service includes top-end overhaul, cylinder inspection, cam-drive servicing, oil-pump alignment and component-specific torque references.
• Fuel systems: Separate carburetor and electronic fuel-injection sections address fuel delivery, intake components, throttle controls and emissions-system connections.
• Chassis and brakes: Coverage includes wheel servicing, steering-head bearings, front forks, rear suspension, hydraulic brakes and model-specific adjustment procedures.
• Drive and transmission: Primary-drive, multi-plate clutch and final-drive belt procedures accompany transmission disassembly, gear inspection and shifter-mechanism service.
• Starting and charging: Starter-motor overhaul, solenoid testing, alternator service and battery checks are supported by circuit diagrams and diagnostic charts.
• Electrical diagnostics: Dedicated troubleshooting covers instruments, ignition, EFI, serial-data communication and the turn signal/turn signal security module (TSM/TSSM).

For mechanically experienced owners and workshop technicians comfortable with component disassembly, precision measurement and circuit testing. The procedures require appropriate lifting equipment, torque tools and task-specific service tools.

Twin Cam Engine Inspection and Overhaul

Compression and cylinder leakdown tests help distinguish valve leakage, worn rings and head-gasket faults before a top-end rebuild. The Engine Oil Flow - Cam Support Plate/Right Crankcase Half diagram supports the lubrication-system explanations.

Cam chain tensioner servicing identifies the required unloading and locking tools; uncontrolled release can stretch the spring or crack the tensioner shoe. Incorrect rocker-housing gasket orientation can expose the breather passage and cause a major oil leak.

Cylinder-head service, piston inspection and cylinder honing are covered. Connecting-rod lower-bearing damage calls for replacement of the flywheel assembly.

Carburetor, EFI and California Emissions Systems

Keihin CV carburetor procedures address the vacuum piston, float system, accelerator pump and enrichener. EFI sections cover injectors, fuel-pump components, idle air control and fuel-pressure testing.

The Schematic-CA Evaporative Emissions Control System identifies purge, vacuum and vent routing. Fuel-filter service and throttle-cable adjustment distinguish carbureted and fuel-injected applications.

Wheels, Suspension and Power Transmission

Wheel removal, bearing replacement, tire mounting and wheel lacing cover 16-, 19- and 21-inch rims. Chassis procedures cover steering-head bearing lubrication, brake-caliper overhaul, fork-seal replacement and FXDX suspension adjustment.

Rear shock absorbers are replaceable units except for their mounting bushings. Lifting equipment must keep the motorcycle securely supported during chassis and powertrain removal.

Drive Belt Wear Analysis supports belt-condition assessment, while Transmission Power Flow explains gear engagement. Sprocket alignment and clutch-pack inspection and adjustment are covered, with a separate appendix for the Japanese mainshaft/countershaft assembly.

Electrical Testing and Fault Isolation

Separate carbureted and EFI circuits help identify the correct module connections and tests for each configuration. The EFI Circuit Diagram links sensors, injectors and ignition outputs; Starter Testing 2: Solenoid Clicks addresses a specific starting symptom.

Alternator-stator replacement, charging-system tests, connector pinouts, wire repair and speedometer self-diagnostics complement the TSM/TSSM fault charts. Circuit testing calls for a digital volt/ohmmeter and the relevant breakout box.

Replacement ECMs and ICMs require Digital Technician programming and password learning; EFI idle adjustment also uses Digital Technician.

A Sample of Drain-Plug Torque and Steering Adjustment Data

These torque and steering-bearing figures are a small selection of the manual's service data. Transmission lubricant service specifies 14-21 ft-lbs (19.0-28.5 Nm) for the drain plug with its O-ring.

For steering-head adjustment, the specified distance between the two fall-away marks is 1.0-2.0 in. (25.4-50.8 mm), measured with the motorcycle level and the front end fully suspended.

PDF Navigation, Diagram Detail and Included Pages

Text search and diagram detail: Searchable text and embedded bookmarks cover both manuals. Dense wiring diagrams require zooming for small connector, pin and wire-color labels.

This printable, English-language download contains one PDF totaling 1,077 pages: 632 for the Service Manual, 444 for Electrical Diagnostics and one combined contents page. These totals already include 16 chapter contents pages, 16 blank pages, 14 notes pages and 82 pages containing only wiring-diagram headings.
