Routine Maintenance and Component Coverage

This factory service reference lays out exacting maintenance schedules for the entire 2006 Softail lineup. It breaks down required inspections and fluid changes across 5,000, 10,000, 15,000, 20,000, and 25,000-mile service intervals. Technicians will find dedicated chapters detailing the starter, drive belt, transmission, and electrical wiring. The documentation delves into specific cleaning, disassembly, and assembly practices, while outlining critical hardware and thread-repair techniques for factory fasteners. Proper maintenance of high-pressure fuel systems and heavy-duty electrical components carries inherent risks; mechanics must always verify battery disconnection and relieve fuel line pressure before beginning any component teardown outlined in these pages. Further guidance includes battery care protocols, brake pad wear limits, and oil system routing.

Specification Highlights

Accurate torque and fluid values are critical for proper reassembly. This documentation provides exact factory reference numbers for the chassis, engine mounts, and electrical subsystems. Front engine mount nuts require a tightening torque of 70–80 ft-lbs (94.9–108.5 Nm). When performing a complete fluid change, the oil tank capacity is firmly documented at 3.5 qt (3.3 L). Transmission drain plugs must be seated to 14–21 ft-lbs (19.0–28.5 Nm) to prevent casing damage or fluid leaks. Additionally, the maintenance quick-reference charts list the standard spark plug torque at 12–18 ft-lbs (16–24 Nm).
