2013 Harley-Davidson Dyna FXDB, FXDBP, FXDBA, FXDC, FXDC ANV, FXDL, FXDF, FXDWG & FLD Service & Electrical Diagnostic Manual Set (P/N 99481-13A)

This 2013 Harley-Davidson Dyna manual set combines the factory Service Manual (P/N 99481-13A) and Electrical Diagnostic Manual (P/N 99496-13). Coverage includes Street Bob, Super Glide Custom and its 110th Anniversary Edition, Fat Bob, Wide Glide, Switchback, and the Japan-market Low Rider.

• Engine repair: Twin Cam 96 and Twin Cam 103 top-end overhaul, cam compartment service, oil pump work, and crankcase disassembly and assembly.

• Drive and transmission: Primary chaincase, compensating sprocket, clutch, drive belt, transmission gearset, and main drive gear and bearing service.

• Chassis and suspension: Wheel lacing and truing, vehicle alignment, steering head bearing adjustment, and front fork overhaul, including the FLD left-side cartridge fork.

• Fuel and emissions: Induction module, fuel pump and injector service, fuel pressure testing, intake leak testing, and California evaporative-emissions components.

• Electrical diagnosis: DTC priority tables, symptom-based troubleshooting, CAN bus fault tracing, starting and charging tests, and ECM, BCM, and security-system diagnosis.

• ABS service: Module and brake line replacement, wheel speed sensor testing, brake bleeding procedures, and circuit-specific diagnostic charts.

The set suits professional technicians and experienced mechanics; the diagnostic manual assumes a basic understanding of electronics and general knowledge of the vehicle.

Twin Cam Engine and Transmission Repair

Top-end procedures cover rocker arm supports, hydraulic lifters, cylinder heads, cylinders, and pistons. Cam support plate service and crankcase bearing work have separate inspection and assembly instructions, supported by wear-limit tables and exploded views.

The Engine Oil Flow: Cam Support Plate/Right Crankcase Half diagram traces lubrication passages through the engine. Crankshaft runout inspection is included, but the crankshaft/flywheel assembly is treated as a nonserviceable replacement unit.

Transmission coverage extends to mainshaft and countershaft inspection, bearing housing removal, and gear assembly. Main drive gear procedures identify the Main Drive Gear/Bearing Remover and Installer (HD-35316-C) and explain the bearing damage that occurs during extraction.

Wheel, Fork, and ABS Variants

Wheel procedures distinguish angle-flange and straight-flange hubs, cast and laced wheels, and ABS encoder bearings. Suspension sections cover rear shock spring preload and steering head fall-away adjustment. Separate FLD left-cartridge procedures and fork specifications for each leg help prevent applying standard FX fork information to the Switchback assembly.

ABS coverage includes the electro-hydraulic control unit (EHCU), brake lines, and wheel speed sensors. The ECU and hydraulic control unit are not separately serviceable. Digital Technician II (HD-48650) is required for programming a replacement ABS module and for the documented ABS bleeding checks.

The manual warns that magnetic fields can damage wheel speed sensors and encoder bearings. Its diagnostic illustrations distinguish the tan outward-facing ABS bearing seal from a reversed red seal and a black non-ABS bearing, alongside the ABS Schematic.

Heavy lifting and brake work require proper support, protective equipment, and close attention to the manual’s safety precautions.

Fuel Injection and Electrical Fault Tracing

EFI troubleshooting separates cranking without starting, hesitation or loss of power, stalling, and misfire concerns. Injector, oxygen-sensor, ignition, and sensor-circuit tests supplement the mechanical fuel-system procedures. California evaporative-emissions work is identified separately.

Electrical diagnosis combines odometer self-diagnostics, DTC priority tables, connector pin information, and circuit tests. The diagnostic procedures are developed for use without Digital Technician II, while the ABS service requirements above still apply.

The CAN Bus Circuit, Charging System Circuit, and EFI Simplified Schematic support fault tracing. Main Harness 1 of 2: 2013 Dyna adds color-coded wiring detail, with connector repair instructions and cable-routing views elsewhere in the set.

A Sample of Oil Pressure, Fuel Pressure, and Brake Torque Data

These examples represent a small selection of the engine, fuel-system, and chassis specifications in the manuals.

Engine oil pressure is specified at 30–38 psi at 2,000 rpm with oil at 230°F (110°C). The fuel pressure test specifies a steady 55–62 psi as engine speed changes.

Front caliper installation tables list 28–38 ft-lbs for both upper and lower mounting bolts. Component-specific torque tables, fluid capacities, wear limits, and electrical test values provide the wider reference data.

Searchable PDF and Publication Bookmarks

Text search, bookmarks, and wiring detail: Both publications have searchable text and embedded PDF bookmarks. Dense main-harness diagrams require zooming to read small pin numbers and wire-color codes.
