2007 Harley-Davidson Sportster XL Service & Electrical Diagnostics Manual Set (P/N 99484-07, 99495-07)

The service manual supplies the mechanical repair procedures and component replacement instructions. The electrical diagnostics publication adds symptom charts, circuit tests and fault-code troubleshooting, with cross-references between the two.

Text Search, Bookmarks and Wiring Detail

Search and navigation: Searchable text and extensive section bookmarks are included. The main Electrical Diagnostics bookmark incorrectly opens the transmission section; its individual section bookmarks provide access to the diagnostic chapters. Small labels in dense wiring diagrams require zooming.

The set contains 986 pages in one printable English-language PDF, including a shared one-page contents cover and 43 blank, notes or diagram-title pages. Those 43 pages are already included in the publication totals above.

Engine Overhaul, Chassis Service and EFI Diagnosis

These are selected areas of coverage. The manuals also include wheel-balancing procedures and headlamp alignment instructions.

• Engine repair: Step-by-step procedures for engine removal and installation, top-end and bottom-end overhaul, cylinder-head service, piston inspection and cam-gear installation.

• Primary drive and transmission: Clutch disassembly, release-mechanism service, internal transmission repair, bearing replacement and secondary drive belt replacement.

• Brakes and chassis: Hydraulic brake bleeding, master-cylinder and caliper repair, laced wheel truing, wheel alignment, steering-head bearing service and front fork oil replacement.

• Fuel injection: Fuel pump and induction-module service, intake leak testing, fuel-pressure diagnosis and testing of IAC, temperature, throttle-position and oxygen-sensor circuits.

• Starting and charging: Starter motor repair, solenoid service, on-vehicle and bench testing, battery checks and charging-system fault isolation.

• Electrical and security systems: ECM and instrument troubleshooting, TSM/HFSM diagnosis, wiring diagrams, connector pin views and Japan/Korea TSM/TSSM procedures.

Suited to mechanically qualified owners and technicians with appropriate service tools; most electrical diagnostic routines require a breakout box and digital volt/ohmmeter.

Engine and Drivetrain Repair

The air-cooled Evolution engine sections distinguish work that can be performed with the engine in the chassis from repairs requiring removal. Compression and cylinder-leakage tests support diagnosis before disassembly, while the overhaul chapters cover valve guides and seats, cylinders, pistons, tappets, oil-pump inspection and crankcase bearings.

Internal transmission service requires engine removal and crankcase separation. The instructions continue through mainshaft and countershaft disassembly, shifter-fork inspection, bearing service and reassembly. Exploded clutch and release-mechanism views identify the spring plate, diaphragm spring and bearing arrangement.

Excessive compression of the clutch diaphragm spring can damage the pressure plate. Pressing the clutch hub and shell apart also requires bearing replacement because separation can damage the bearing.

Maintenance, Wheels and Brakes

Maintenance schedules sit alongside adjustment procedures for primary chain tension, clutch release and rear belt deflection. Fork-oil instructions distinguish XL 883L/XL 1200L requirements from the other models and separate assembled-fork filling from oil-level measurement during disassembly.

Wheel service includes lacing and truing, wheel-bearing replacement and alignment checks. Front and rear caliper exploded views accompany inspection and assembly procedures. Component torque tables and the Gearcase Cover Mounting Screw Torque Sequence provide assembly references.

EFI Fault Finding and Electrical Testing

The diagnostic flowcharts connect symptoms and trouble codes with circuit diagrams, connector tables and test results. This supports tracing a starting or running problem through wiring, power supply and component checks before choosing a repair.

Coverage includes cranking without starting, stalling, misfire, IAC operation, vehicle speed sensor faults and oxygen-sensor diagnosis. The Serial Data Circuit diagram and connector tables identify the ECM’s 36-place Packard connector beneath the seat, where the module mounts on the rear fender. The California Evaporative Emissions Control System schematic shows the canister and vapor-valve plumbing; fuel pump module exploded views support component service.

ECM replacement requires reprogramming with Digital Technician HD-44750 and the applicable password-learn procedure. For pressurized fuel systems and high-current electrical work, follow the manual’s fuel-depressurization and battery-isolation precautions.

Selected Chassis Limits and EFI Test Data

Brake pad inspection specifies replacement when friction material reaches 0.04 in. (1.02 mm) or less above the backing plate. The chassis torque tables list 50–55 ft-lbs (68–75 Nm) for the front axle nut.

The EFI fuel-pressure test specifies a steady 55–62 psi (380–425 kPa) with the engine running as engine speed changes.
