QISF Universal Flywheel Stator Magneto Puller 110mm – Iron Puller with Bolts for Yamaha YBR 125, Motorcycles & ATVs

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

When you need to remove a stuck flywheel or rotor, using the right puller prevents costly thread or component damage. This QISF puller is a universal-style tool with a 110 mm (4.3 in) main base diameter and includes the bolts required to attach to a range of models. It's built from robust iron for reliable leverage and repeated workshop use.

Will this puller work on my Yamaha YBR 125 or similar bikes?

Yes — the QISF puller is compatible with many small-displacement motorcycles and scooters, including Yamaha YBR 125 and comparable models. Its universal pattern and included bolts let you mount the tool to various stator/rotor layouts.

• Fits many motorcycles, scooters and small engines such as Yamaha YBR and SRZ150 variants.
• 110 mm base diameter matches common flywheel sizes on small bikes.
• Includes mounting bolts for straightforward attachment to rotors and stators.

How does it protect crankshaft threads and parts during removal?

The puller applies even, centered pulling force, eliminating the need to hammer or pry on the crankshaft end. This controlled extraction reduces strain on threads and prevents bending or cracking of nearby components.

• Central pressure screw draws the flywheel straight off the taper.
• Wide iron base spreads the load across the rotor surface to avoid point stresses.
• Properly sized bolts secure the puller to the rotor to prevent slippage.

What other machines and tasks is this useful for?

The QISF puller is versatile enough for ATV, PWC, lawn mower and small marine engine work. It can remove flywheels, alternators, generators and magneto rotors on a variety of outdoor-power and recreational engines.

• Removes flywheels from ATVs, personal watercraft and dirt bikes.
• Useful for lawn mower and chainsaw engine service jobs.
• Works on many small outboard motors and portable generators requiring rotor removal.

How durable and easy to use is the tool?

Manufactured from iron, this puller stands up to workshop use and repeated torque. The straightforward design and included hardware make it quick to set up: mount, secure the bolts, and turn the center screw to extract the rotor.

• Iron construction offers long-term strength and resistance to bending under load.
• Simple mounting pattern minimizes parts swapping between jobs.
• Compact 110 mm diameter balances accessibility inside tight engine covers.

Who this tool is for: The QISF Universal Flywheel Stator Magneto Puller is ideal for home mechanics, small-engine technicians, motorcycle and ATV owners, and marine hobbyists who perform routine service or restoration. If you frequently remove rotors, stators or flywheels on small engines and want a safer, faster method that preserves crankshaft threads and surrounding components, this tool belongs in your toolbox.
