HIAORS GY6 Flywheel Puller & Clutch Lock Nut Tool Kit — 24mm/27mm Puller, 20mm/24mm Sockets for 50–150cc Bikes

HIAORS two-piece tool kit combines a GY6 stator/flywheel puller (24mm & 27mm) and a clutch lock nut spanner/socket (20mm & 24mm) to remove and install flywheels and clutch lock nuts on 50–150cc motorcycles, ATVs, pit bikes and scooters. This compact kit brings two workshop essentials together so riders and home mechanics can separate tapered flywheels and secure or release clutch lock nuts without improvising with wrong-sized wrenches. The set is machined to fit common small-engine sizes and works with many GY6-style engines and popular 50–150cc machines, letting you service stators, magnetos and clutches more quickly and with less risk of damage.

Which engines and bikes will these tools fit?

The puller and spanner were designed for small-displacement, single-cylinder bikes and ATVs that use GY6-style magnetos and standard clutch lock nut sizes. They fit a wide range of 50cc to 150cc scooters, pit bikes, quads and go-karts from many common manufacturers.

• GY6-type 50cc, 125cc and 150cc engines compatible with 24mm & 27mm puller sizes
• Clutch lock nut tool fits 20mm and 24mm lock nuts on many 50–125cc models
• Useful for scooters, pit/dirt bikes, ATVs, quads and small go-karts

How do I use the flywheel puller safely and effectively?

Thread the puller into the flywheel’s threaded holes and tighten the center bolt to press the flywheel off the crank taper evenly. Use steady, even force and confirm threads are engaged so the puller extracts the flywheel without bending or marring components.

• Match the puller size (24mm or 27mm) to the engine’s threaded hole diameter
• Ensure clean threads and hand-start bolts to avoid cross-threading
• Tighten center bolt gradually until the flywheel works free from the crank taper

When should I use the clutch lock nut spanner, and how does it help?

The clutch lock nut spanner is intended to hold or remove the lock nut that secures the clutch assembly during repairs or replacements. Its sockets are sized to fit common small-engine lock nuts so you can torque or loosen them without slipping or damaging the nut face.

• Use the 20mm or 24mm socket depending on the lock nut size
• Pair with a breaker bar or torque wrench where required for safe loosening/tightening
• Works to lock the clutch while removing the nut or to hold parts during reassembly

What comes in the package and what materials/finish can I expect?

The kit ships with one GY6 magneto flywheel puller and one clutch lock nut spanner covering the sizes listed. The tools are built for workshop use; expect metal construction with durable machining for thread engagement and socket fit.

• Included: 1 × GY6 magneto flywheel puller (24mm & 27mm compatible)
• Included: 1 × clutch lock nut tool / spanner (20mm & 24mm sockets)
• Designed for repeated mechanical use on small-displacement engines

Who is this for This HIAORS kit is aimed at DIY mechanics, home garage owners and professional technicians who service 50–150cc motorcycles, scooters, pit bikes and ATVs. If you need a reliable, size-specific puller for GY6-style flywheels and a matched clutch lock nut spanner to speed clutch work and stator replacement, this compact two-piece set covers the common sizes without needing multiple specialty tools.
