2006 Harley-Davidson Dyna FXD, FXDC, FXDL, FXDWG, FXD35, FXDB Factory Service & Electrical Diagnostics Manual Set (P/N 99481-06)

This 2006 Harley-Davidson Dyna Manual Set combines the Service Manual, P/N 99481-06, and Electrical Diagnostics, P/N 99496-06, for FXD, FXDC, FXDL, FXDWG, FXD35, and FXDB models. Together, the publications cover scheduled maintenance, mechanical repair, and electrical fault isolation.

• Maintenance and chassis: Scheduled service, hydraulic brake bleeding, front-fork overhaul, steering-head adjustment, wheel-bearing replacement, wheel lacing, and vehicle alignment.

• Engine repair: Engine removal and installation, top- and bottom-end overhaul, compression and cylinder-leakage testing, and oil-pump inspection.

• Primary drive and transmission: Clutch disassembly, primary-chain and tensioner service, drive-belt replacement, transmission teardown, and main-drive-gear bearing work.

• Fuel and emissions: EFI component service, fuel-pump assembly service, fuel-pressure and intake-leak tests, and California evaporative-emissions coverage.

• Electrical diagnosis: Starter and charging tests, instrument troubleshooting, TSM/TSSM diagnostics, key-fob assignment, password learning, and engine-management fault charts.

• Wiring and connectors: Model-specific wiring diagrams, connector locations, pin assignments, and terminal service for AMP Multilock, Deutsch, Mini-Deutsch, and Packard connectors.

This set suits mechanically experienced owners and technicians with the specified measuring equipment and special tools; internal engine and transmission work assumes workshop repair skills.

Chassis and Maintenance Coverage

Scheduled service sections cover engine oil and filter intervals, primary-chaincase lubrication, clutch adjustment, rear-belt deflection, and spark-plug inspection. The Quick Reference Maintenance Chart brings routine checks together; Battery Self-Discharge Rate and Drive Belt Wear Patterns support storage and belt-condition assessment.

Transmission lubricant checks are specified with the motorcycle at operating temperature on the jiffy stand.

Chassis procedures cover front and rear wheel removal, laced-wheel truing, and separate lacing instructions for 17-, 19-, and 21-inch rims. Brake caliper and master-cylinder repair, steering-bearing fall-away adjustment, and rear-axle torque and spring-clip alignment are documented. Rear shocks are replacement assemblies except for their rubber mounting bushings.

Support the motorcycle securely and follow the manual's brake-system and lifting precautions.

Engine, Primary Drive, and Transmission Repair

The engine chapters distinguish top-end and cam-compartment work with the engine installed from flywheel-compartment service requiring engine removal and crankcase separation. Cylinder-head, piston, breather, rocker-arm support plate, cam-support plate, and oil-pump sections provide inspection limits and assembly details. The flywheel/connecting-rod section specifies complete assembly replacement for defined defects.

Transmission coverage reaches mainshaft/countershaft disassembly, shift-drum and fork inspection, side-door bearings, and main-drive-gear service using remover/installer HD-35316-C. Primary-drive procedures warn that locking tool HD-41214 can damage components and specify HD-47977 for that work.

The clutch sections explain how excess primary lubricant can cause rough engagement, drag, and difficulty finding neutral, while hot adjustment can leave inadequate pushrod-bearing clearance and cause slippage when cold.

EFI Components and Market Differences

EFI coverage distinguishes domestic oxygen-sensor equipment from the HDI active-intake system. Fuel-pump procedures address the filter, regulator, inlet sock, and sender assembly. The EFI System Circuit schematic and model-specific Top Plate Torque Sequence drawings support this work.

Idle-speed adjustment requires Digital Technician HD-44750. The manual also documents California evaporative-emissions plumbing and intake-leak testing.

Electrical Fault Isolation and Security Systems

Diagnostic charts address no-start conditions, starting followed by stalling, misfire, charging faults, and instrument failures. The DTC priority tables help separate serial-data faults from secondary codes before individual components are condemned.

Speedometer self-diagnostics provide code access; distinguishing current from historic faults requires Digital Technician. EFI circuit tests use breakout box HD-43876 with a digital volt/ohmmeter. TSM/TSSM coverage includes turn-signal cancellation, bank-angle sensing, security configuration, and replacement-module password learning.

Wiring sheets distinguish FXDWG/FXD35 circuits from the other Dyna models, with domestic and international equipment identified where applicable.

A Sample of Torque and Ignition-Coil Specifications

These values are a small selection of the service specifications in this set.

For primary-chaincase service, the drain-plug specification is 36–60 in-lbs (4.1–6.8 Nm). Following steering-head adjustment, the upper triple-clamp pinch bolts are specified at 30–35 ft-lbs (40.7–47.5 Nm).

The ignition-coil specification gives a primary-winding resistance of 0.3–0.5 ohms at room temperature, supporting the coil-testing procedures.

Text Search, Bookmarks, and the Combined PDF

Navigation and diagram detail: Searchable text and embedded bookmarks cover both publications. Small pin numbers and wire-color labels on dense wiring sheets are best read at higher zoom.

Both publications are supplied in one printable English PDF totaling 914 pages, including the shared contents sheet.

The shared contents sheet accounts for the remaining page. The total already includes 15 blank pages, 11 notes pages, and 42 wiring continuation pages carrying headings only.
