2006 Keeway ARN125 / ARN150 Service & Repair Manual (OEM)

• Original OEM publication (February 2006 first edition) covering 2006 Keeway ARN125 and ARN150 scooters
• Provides the primary factory reference data used for the initial ARN series production launch
• Features 47 exploded-view diagrams, 8 detailed torque specification tables, and 2 complete electrical circuit diagrams
• Covers teardown and rebuild documentation for the kick starter, driven wheel disc clutch, super clutch, oil pump, front fork, magneto stator, and CDI unit
• Includes essential visual aids such as wiring diagrams, charging system circuit diagrams, power transfer charts, fault inspection charts, engine cycle illustrations, fuel consumption curves, and valve clearance setup views

Component and System Documentation

Delivered as an 85-page PDF (P/N: FEB.2006), the documentation begins with foundational engine theory and work cycles. From there, it jumps straight into the mechanical teardown reference for comprehensive repair work. You will find exact schematics for the engine and transmission that detail internal assemblies alongside valve clearance limits. If you need to verify cylinder health, the baseline pressure metrics are clearly charted. This manual provides the specific step-by-step procedures to confidently tackle tasks that typically require an expensive trip to the dealership, such as front fork oil replacements, valve clearance adjustments, and hydraulic disc brake bleeding. The fuel system sections document carburetor configurations, detailing the removal, installation, and tuning parameters. Further chapters break down the chassis architecture, front suspension components, and disc brake hardware configurations.

Technical Specifications and Data

Accurate measurements are the backbone of a reliable rebuild. This manual delivers the specific figures necessary for precision component assembly, streamlining daily shop workflows by allowing technicians to verify mechanical wear limits directly at the workbench. Cylinder head bolts require a strict 10–12 N·M torque across the designated tightening sequence. Front fork oil capacity is specified at precisely 100±2 ml per leg for the 125cc model. Fuel delivery is equally precise; the factory specs list a 179# main nozzle for the PD24JC carburetor. The text specifies ignition timing at 15° BTDC at 1700 RPM, while crankcase assembly torque mirrors the top end at 10–12 N·M. A dedicated fault inspection chart helps track down ignition, fuel, and mechanical anomalies by cross-referencing running symptoms for efficient troubleshooting. You will also find electrical reference values mapping magneto resistance and battery charging currents. Always observe standard shop safety protocols when handling pressurized fuel or hydraulic lines. Proper protective gear and a clean workspace are just as critical as relying strictly on these OEM metrics to verify your work.
