The 6-in-1 Flywheel Puller Tool is a multi-vehicle engine specialty service tool manufactured from heat-treated carbon steel with an anti-oxidation black oxide finish. This all-in-one mechanic tool combines the six most frequently encountered metric sizing specs into a single compact cross-type layout, allowing you to separate tapered lock-type magneto rings, alternators, and stators from engine crankshafts without inflicting damage on expensive components.

Technical Specifications & Thread Pitch

The integrated body utilizes precise metric threading configurations optimized for different powersports and small-engine architectures:

• M10 × 1.25R: Right-hand thread male connection.
• M14 × 1.5R: Right-hand thread male connection.
• M16 × 1.5R: Right-hand thread male connection.
• M18 × 1.5R: Right-hand thread male connection.
• M24 × 1.0R: Right-hand thread male connection.
• M27 × 1.0L: Left-hand thread (Reverse threaded).

This combination setup replaces individual pullers across small-engine platforms:

Japanese Motorcycles: Services various classic and modern magneto systems from Honda, Kawasaki, Suzuki, and Yamaha.

• Moped & Scooter Engines: Fits standard 50cc to 150cc GY6 4-stroke engines. The M24 size services GY6 50cc platforms, while the M27 left-hand thread handles GY6 125cc and 150cc variants.
• Japanese Motorcycles: Services various classic and modern magneto systems from Honda, Kawasaki, Suzuki, and Yamaha.
• Off-Road Platforms: Compatible with smaller displacement dirt bikes, ATVs, and European engines like KTM.

• Operation Best Practices

1. Thread Cleanout: Prior to screwing the tool into place, clear out dirt and debris embedded within the internal threads of the flywheel ring using brake cleaner and a wire brush.
2. Thread Engagement: Always thread the tool fully by hand into the target component until it bottoms out completely. Partial thread insertion will strip out the soft metal walls under heavy load.
3. Drive System: Lubricate the central forcing bolt with anti-seize or motor oil, then rotate it slowly against the crankshaft snout using hand tools (such as a wrench or T-handle socket) to cleanly pop the tapered press-fit joint free. Avoid aggressive air impact guns unless specified by your repair manual
