Flywheel puller for OS SPEED

The O.S. Engine OS71415100 flywheel puller is a dedicated RC-scale service tool designed to extract OS SPEED flywheels safely and with control. Its purpose is simple: provide a controlled extraction method so you can access clutch, crankcase, and piston components without damaging the flywheel or crankshaft threads.

In practice, the tool threads into the flywheel hub and uses a central extraction action to separate the flywheel from the crank. Its role in setup and tuning is to let you remove the flywheel frequently during carburetor adjustments, clutch servicing, or when swapping engine components during bench tuning and maintenance.

Use the puller with care, ensuring the engine is secured and threads are clean before engagement to reduce the risk of cross-threading or component damage.

How do I use this flywheel puller safely?

Thread the puller into the flywheel hub by hand, confirm it seats squarely, then apply steady extraction force until the flywheel releases, keeping the engine secured throughout.

Will this fit non-OS flywheels?

The tool is specified for OS SPEED flywheels; verify thread form and hub design on other brands before attempting use to avoid thread damage.

How should I maintain the puller?

Keep threads clean and lightly lubricated, inspect for wear before use, and store the tool dry to prevent corrosion that can affect fit and function.

What problems can occur when removing a stuck flywheel?

Sticking is often due to debris or corrosion; avoid excessive force, stop if threads bind, clean the hub, and reassess to prevent thread stripping.
