Threaded extractor for OS SPEED flywheels

The O.S. Engine OS71415100 flywheel puller provides a controlled extraction method for OS SPEED flywheels, allowing quick access to clutch and internal engine components during tuning sessions. The tool threads into the flywheel hub and pulls centrally to avoid lateral stress on the crankshaft or hub threads.

Its straightforward design makes it useful when you need to remove the flywheel frequently during carburetor adjustments, clutch checks, or when swapping internal parts while bench tuning an engine.

Before operation, secure the engine and ensure both tool and hub threads are clean to prevent cross-threading or damage during repeated removals.

How frequently can I remove the flywheel during tuning with this tool?

The puller is designed for repeated use; however, inspect threads regularly and avoid unnecessary removals to minimise wear on hub and tool threads.

Will using the puller affect engine balance or timing?

Proper use of the puller should not affect balance or timing. Always reinstall the flywheel correctly and verify timing marks after reassembly.

Are there torque considerations when reinstalling the flywheel?

Torque settings vary by engine; follow the engine manufacturer's guidance for flywheel and crankshaft fastener torque to ensure proper seating and function.

What steps help prevent thread damage during frequent removals?

Keep threads clean and lightly lubricated, start the puller by hand to ensure correct engagement, and stop if any binding or cross-threading is detected.
