HIAORS GY6 Flywheel Puller & Clutch Lock Nut Spanner Kit 24/27mm Puller 20/24mm Spanner 50-150cc

HIAORS delivers a compact two-piece service kit: a GY6 stator/flywheel puller (24mm & 27mm) plus a clutch lock nut spanner/socket set (20mm & 24mm) made for 50–150cc motorcycles, ATVs and scooters.

Whether you’re doing routine maintenance or replacing a stator or clutch, this HIAORS tool set provides the specific sizes and fitments commonly used across many GY6-based scooters, pit bikes and small quads. The kit includes the puller that separates the flywheel from the crank taper and a dual-size clutch lock nut tool designed to hold and turn locknuts without damaging surrounding components. Both pieces are compact, straightforward to use, and packed to serve as a practical addition to a home garage or a professional mechanic’s ride service kit.

Which engines and models will these tools work with?

The set targets GY6-style engines and many small-displacement motorcycles and ATVs. The flywheel puller fits popular 50cc, 125cc and 150cc GY6 engines, and the clutch lock nut spanner covers common locknut sizes found on 50–125cc dirt bikes and scooters.

• Fits GY6 50cc/125cc/150cc engines from Roketa, Taotao, Jonway, Znen and similar brands.
• Clutch spanner compatible with 50cc–125cc pit bikes, scooters and ATVs.
• Replaces specific Honda-style service tool references for certain models.
• Included sizes: flywheel puller 24mm & 27mm; clutch spanner 20mm & 24mm.

How do I use the flywheel puller safely and effectively?

Use the puller after removing the flywheel nut and any external covers. Thread the puller into the flywheel or stator hub per the engine’s service manual, then turn the central bolt until the flywheel releases from the crank taper. Keep threads clean and turn slowly to avoid stripping or sudden releases.

• Always consult the vehicle manual for correct bolt torque and removal sequence.
• Thread the puller evenly and use steady pressure — avoid hammering.
• Inspect threads and mating surfaces before reassembly to prevent damage.
• Use appropriate safety gear and support the bike or ATV securely.

When should I use the clutch lock nut spanner and how does it protect parts?

The clutch lock nut spanner holds or turns the locknut during clutch removal and installation, preventing the clutch hub from rotating while you loosen or tighten the nut. Its socket-style engagement reduces slippage and minimizes marring of the nut face compared with improvised tools.

• Use to lock the clutch hub when removing or installing the lock nut.
• Dual sizes (20mm & 24mm) cover common nut diameters on small bikes and scooters.
• Designed to reduce rounding and damage to the nut edges during service.
• Works alongside a breaker bar or torque wrench for controlled force application.

What’s included and what should I check before buying?

The package contains one GY6 magneto/flywheel puller and one clutch lock nut tool. Before purchasing, confirm the flywheel thread size and lock nut diameter on your specific engine to ensure the included sizes match your bike or ATV.

• Contents: 1 × GY6 flywheel puller (fits 24mm & 27mm) and 1 × clutch lock nut tool (20mm & 24mm).
• Verify your engine model and part dimensions against the tool sizes.
• Check for compatibility notes if your machine uses a proprietary or non-standard nut/thread.
• Keep packaging and instructions for reference during future maintenance.

Who is this for: This HIAORS set is aimed at DIY mechanics, scooter and pit-bike owners, and light-duty repair shops needing the correct puller and lock nut sizes for GY6-style engines and many 50–150cc machines. If you perform routine stator, flywheel or clutch work and want dedicated, size-accurate tools that reduce risk of damage, this compact kit is a practical choice.
