Motion Pro Flywheel Puller M27x1.0 Left-Hand 27mm External-Thread — Heat-Treated Steel, Precision Threads

Motion Pro 08-0026 is a 27 mm left-hand external-thread flywheel puller designed to remove external flywheels on most single-cylinder engines quickly and safely.

This compact, purpose-built tool gives technicians and home mechanics a straightforward way to extract external-threaded flywheels without damaging the crankshaft, stator, or surrounding casing. Machined and heat-treated for strength, the M27x1.0 left-hand puller engages the flywheel threads and uses controlled pressure to separate the flywheel from the taper. It's a focused replacement or addition to a mechanic's toolkit when working on motorcycles, ATVs, scooters, or small engines that use a 27 mm external flywheel thread.

How does this puller work on external-thread flywheels?

The tool screws into the flywheel's matching M27x1.0 left-hand threads; a central forcing bolt then presses against the crankshaft nose to push the flywheel free. Using the correct thread engagement and a single-point forcing action reduces the risk of cocking or uneven forces that can damage parts. Because the puller is left-hand threaded, it matches flywheels that loosen in the standard right-hand direction during removal.

• M27x1.0 left-hand external thread for proper fit
• Central forcing bolt applies straight, even pressure
• Threaded engagement minimizes slippage and marring

What materials and construction give this tool durability?

Motion Pro builds this model from heat-treated steel that resists bending and wear under the torques and stresses encountered during flywheel removal. Precision machining ensures the threads seat fully and the forcing bolt rides true, so the tool holds up over repeated use. This construction makes it appropriate for both infrequent home repairs and routine shop work.

• Heat-treated steel for strength and longevity
• Precision-machined M27x1.0 threads for repeatable fit
• Robust forcing bolt designed for repeated service

Which engines and applications is the M27x1.0 puller compatible with?

The puller is sized for most single-cylinder engines that use a 27 mm external-threaded flywheel with an M27x1.0 left-hand thread pitch. It's commonly used on many small-displacement motorcycles, scooters, dirt bikes, ATVs, and some lawn and utility engines. Always verify thread size and direction on the flywheel before use to ensure proper fit and avoid damage.

• Designed for single-cylinder engines with 27 mm external flywheels
• Matches M27x1.0 left-hand threaded flywheels
• Suitable for motorcycles, ATVs, scooters, and small engines

How should I use and maintain the puller safely?

Screw the puller fully into the flywheel threads by hand, confirm full thread engagement, then tighten the central bolt gradually until the flywheel breaks free. Use the correct driver or socket on the forcing bolt and avoid excessive impact that could damage the puller or crank nose. After use, clean threads, apply light anti-seize if storing for long periods, and inspect for wear or distortion.

• Hand-thread fully before applying force
• Tighten forcing bolt evenly; avoid hammer strikes
• Clean, inspect, and lightly lubricate threads for storage

Who is this for: The Motion Pro 08-0026 M27x1.0 flywheel puller is for home mechanics, professional technicians, and race shop crews who regularly service single-cylinder engines with external-threaded flywheels. If you need a compact, heat-treated tool that fits 27 mm external threads and provides controlled, repeatable removal without marring components, this puller is a practical addition to your tool kit. Confirm your flywheel uses an M27x1.0 left-hand thread before purchasing to ensure compatibility.
