• ABS electro-hydraulic control unit (EHCU) module service and bleeding
• Cartridge fork disassembly specifically for FLD models

Manual Contents

Designed for professional technicians and experienced mechanics, this service publication details the architecture of the 2013 Harley-Davidson Dyna platform. Having the exact factory tolerances and routing layouts available directly at the bay prevents costly rework and accelerates complex bench jobs. It documents precise maintenance, removal, and assembly procedures. You will find extensive breakdowns of major systems, ranging from top-end overhauls and cam compartment service to full crankcase disassembly. Beyond the powertrain, the documentation explores the transmission assembly, fuel system components, and intricate electrical modules like the ECM and BCM. Chassis-specific tasks are thoroughly outlined. Expect precise parameters for front and rear wheel service, tire replacements, steering head bearing adjustments, and suspension tuning for both FLD and standard FX models.

Specification Highlights

High-depth reference data is the core of this factory manual, delivering the exact bolt torque values, fluid capacities, and electrical pinouts required for professional shop work. The primary chaincase lubricant capacity is specified at 32 oz for wet refills. In the chassis section, front brake caliper mounting bolts are documented at 28–38 ft-lbs, while intake valve clearance sits at 0.038–0.043 inches.

When servicing these specific models, technicians must be aware of certain mechanical traps. For instance, exposing the active wheel speed sensors to magnetic parts trays or dial indicators will instantly ruin the sensor calibration. Furthermore, a correctly installed ABS wheel bearing features a tan seal facing outward; installing it backward with the red seal exposed, or substituting a black non-ABS bearing, triggers an immediate system fault.

Working on heavy motorcycles involves inherent risks to vehicle integrity and personal safety. Adhering closely to these documented factory limits, while using specialized lifting equipment and appropriate gear, is crucial to preventing injury or component failure during complex powertrain procedures. The text also details diagnostic thresholds, fuel-injection specifications, and factory service intervals for the complete lineup.
