Extraction tool for OS SPEED flywheels

The O.S. Engine OS71415100 flywheel puller is a precision RC workshop tool designed to thread into OS SPEED flywheel hubs and extract them without harming the crankshaft or flywheel threads. It is intended to let you remove the flywheel repeatedly and safely while servicing the clutch, crankcase, piston, or other engine parts.

In use the puller engages the flywheel hub threads and applies a central extraction force to separate the flywheel from the crank. This controlled action is useful when performing carburetor adjustments, clutch maintenance, or bench tuning where regular disassembly is required.

Always secure the engine and ensure threads are clean before using the tool to reduce the risk of cross-threading or component damage.

What is the correct way to start threading the puller into the flywheel?

Begin by hand-threading the puller so it seats squarely in the hub. Confirm it runs true and then apply steady, even extraction force while the engine is firmly clamped to prevent movement.

Can I use this on non-OS flywheels?

The tool is specified for OS SPEED flywheels. Check the thread form and hub design on other manufacturers before attempting use to avoid damaging threads.

How should I look after the puller between uses?

Keep the threads clean and lightly lubricated, inspect for signs of wear, and store the tool in a dry place to prevent corrosion that could affect fit.

What should I do if the flywheel is stubborn and will not release?

Sticking is commonly caused by debris or corrosion. Stop if threads bind, clean the hub, and reassess rather than forcing the puller to avoid thread stripping.
