Motion Pro Flywheel Puller M27x1.0 (27mm) Left-Hand Thread — Heat-Treated External Puller for Single-Cylinder Engines

Motion Pro 08-0026 is a 27 mm, left-hand threaded external flywheel puller engineered to remove external-thread flywheels from most single-cylinder engines quickly and without damage.

Designed for mechanics and DIY riders who service small single-cylinder engines, this compact tool uses an M27x1.0 left-hand thread to engage the flywheel securely and extract it evenly. Heat-treated construction gives the puller the strength to withstand repeated use while minimizing the risk of bending or stripping delicate flywheel threads. It’s a straightforward, purpose-built tool for safely separating flywheels from crankshafts where an external-threaded interface is present.

What engines and flywheels will this puller work with?

The Motion Pro 08-0026 is sized specifically for flywheels that accept a 27 millimeter external puller with an M27x1.0 left-hand thread. It’s most commonly used on single-cylinder motorcycles, scooters, dirt bikes, ATVs, and small engines that share that thread standard. Check your service manual or measure the flywheel thread to confirm compatibility before ordering.

• Thread size: M27 x 1.0, left-hand.
• Nominal puller outer diameter: 27 millimeters.
• Commonly fits many single-cylinder engines, dirt bikes, scooters, and ATVs.
• Not for internal-thread flywheels or non-standard pitch threads.

How do I use this puller safely and effectively?

Using the puller involves threading the tool into the flywheel’s external threads and turning the central forcing bolt to push against the crankshaft, drawing the flywheel off evenly. Use a torque wrench or hand tools and follow the vehicle manufacturer’s instructions for holding the crankshaft to prevent rotation. Always support the flywheel as it comes free to avoid sudden drops.

• Thread puller into flywheel until fully engaged; ensure correct left-hand orientation.
• Use the central forcing screw to press against the crankshaft or supplied pilot.
• Hold or lock the crankshaft to prevent torque-related damage.
• Wear eye protection and support the flywheel as it separates.

What are the key construction and durability features?

This model is heat-treated to improve strength and resistance to wear when removing seized or tightly fitted flywheels. The design keeps forces centered to reduce the chance of thread damage to the flywheel and the tool. That makes it a reliable choice for routine maintenance and occasional heavier-duty extraction jobs.

• Heat-treated steel for increased durability and longevity.
• Precision threads sized M27x1.0 left-hand for accurate engagement.
• Simple, compact form factor for easy access in confined spaces.
• Made to resist bending and stripping under normal service loads.

Who is this for? The Motion Pro 08-0026 is intended for motorcycle and small-engine technicians, home mechanics, and riders who work on single-cylinder machines that use an external-thread flywheel with an M27x1.0 left-hand thread. If you regularly perform engine top-end work, stator service, or flywheel-related repairs and need a reliable, purpose-built extraction tool, this puller offers a focused solution. If your engine uses an internal-thread flywheel or a different pitch/diameter, select a puller matched to those specifications to avoid cross-threading or damage.
