QISF Universal Flywheel Stator Magneto Puller 110mm Iron Base with Bolts — Fits Yamaha YBR 125, Motorcycles & Small Engines

QISF Universal Flywheel Stator Magneto Puller is a heavy‑duty iron tool set designed to extract flywheels, stators, and magnetos from motorcycles, ATVs, lawn equipment, and small engines without damaging crankshaft threads.

Whether you’re a home mechanic or a professional technician, removing a stuck flywheel or magneto can be time‑consuming and risky. This universal puller kit by QISF offers a simple, robust solution: a 110 mm iron main base and matching bolts that safely pull rotors, dynamos, and alternators from a wide range of vehicles and equipment. It’s made to work with models like Yamaha YBR 125 and other small engines, and it helps prevent thread damage and expensive repairs.

How does this puller protect crankshaft threads when removing a flywheel?

The tool applies even pulling force across the flywheel face so parts separate cleanly without twisting or overloading the crankshaft threads. Using the correct bolts and the flat iron base distributes pressure evenly.

• Iron main base spreads force across the rotor surface.
• Bolts thread into factory holes to pull without levering on the crank.
• Fits a 110 mm rotor diameter for common small engines.

What types of engines and machinery will this puller work with?

This universal tool is compatible with many small engines, including motorcycles, ATVs, PWCs, lawn mowers, chainsaws, and some outboard motors. It’s designed for models where a 110 mm base and standard flywheel bolt pattern make sense.

• Motorcycles such as Yamaha YBR and similar models.
• ATVs, personal watercraft, and small marine motors.
• Lawn and garden equipment plus chainsaws and small engines.

How do I use the QISF magneto puller safely and effectively?

Installation is straightforward: remove any retaining nut, screw the supplied bolts into the flywheel’s threaded holes, position the iron base over the rotor, and tighten until the flywheel comes free. Work slowly and keep threads clean to avoid cross‑threading.

• Remove the nut or retaining fastener first to expose bolt holes.
• Use supplied bolts that align with existing threaded holes.
• Tighten evenly and use hand tools to avoid sudden releases.

What are the size and material specifications of the kit?

The set includes a 110 mm (4.3 in) iron main base and appropriate bolts sized for common small‑engine flywheels. The durable iron construction resists bending and provides dependable leverage during removal.

• Main base diameter: 110 mm / 4.3 inches.
• Material: solid iron for strength and stability.
• Package: one complete magneto/flywheel puller set with bolts.

Who is this for? The QISF Universal Flywheel Stator Magneto Puller is made for do‑it‑yourself mechanics, workshop technicians, and vehicle owners who maintain motorcycles (including Yamaha YBR 125), ATVs, small watercraft, lawn equipment, and chainsaws. If you need a reliable tool to remove stuck flywheels or stators without harming threads or housings, this affordable iron puller is designed to simplify the job and reduce the chances of costly damage.
