Content and Maintenance Coverage

This factory PDF documentation details the exact systems needed to keep the 2010 Harley-Davidson Dyna line on the road. It guides technicians through comprehensive maintenance and complex repair jobs that usually demand an expensive dealership visit, such as truing laced wheels, rebuilding the front fork, and navigating the H-DSSS security password learning process. You will find complete schedules for routine engine, transmission, and primary chaincase fluid changes. Need to handle complex chassis alignment or adjust the suspension? It is all outlined here, helping you find a permanent fix for handling issues. The manual also breaks down air cleaner servicing, exhaust system leak testing, and battery care.

Electrical diagnostics are heavily supported with precise fuse locations and relay testing requirements. Alongside the standard wiring diagrams, you can access connector repair views, engine oil flow schematics, drive belt wear charts, torque sequence diagrams, and terminal crimping drawings.

Before starting any shop work, always ensure the motorcycle is properly secured on a lift and you are wearing the correct protective equipment for handling fluids and heavy components. Please note that this page describes the reference material and specifications found within the document, rather than providing the step-by-step repair instructions themselves. The guide ensures owners and technicians can perform service to factory standards directly on the shop floor.

Specification and Reference Data

Precision matters in the workshop. This technical reference packs detailed spec tables for tire pressures, drive belt deflection, and exact fastener torque values—spanning from 6 in-lbs up to 105 ft-lbs. By providing exact factory service wear limits, this resource protects mechanics from stripping delicate aluminum crankcase threads or misaligning the primary chain. For instance, engine oil capacity for the 96 cubic inch power plant is precisely documented at 2.4 liters. It also lists vital diagnostic thresholds like spark plug cable resistance, specifying 4750 to 12,675 ohms for the front cable. Transmission lubricant levels are clearly defined. This helps prevent the common issue of overfilling during routine checks, saving you time and avoiding blown seals.

Understanding model-specific nuances is crucial for preventing costly teardowns. When executing a Twin Cam bottom end overhaul, mechanics must ensure the oil pump is perfectly centered before final torquing to prevent severe sumping and low oil pressure. Additionally, the 6-speed transmission mainshaft clutch hub nut features left-hand threads; applying heavy breaker-bar force in the wrong direction will strip the shaft, a frequent pitfall that this documentation helps you avoid.
