Flywheel Puller

A flywheel puller is a special tool designed to quickly and safely remove a flywheel from the crankshaft of an engine without damage. Using the correct flywheel puller and using it properly will help you avoid damaging the threads on the crankshaft end. It is important to note that flywheels contain magnets which can be damaged or ruined if the flywheel is struck by a hammer or lands on the ground.

Flywheels usually fit onto a tapered shaft and become wedged onto the shaft when the flywheel bolt is torqued down, making the flywheel difficult and unsafe to remove without a flywheel puller. Gloves and goggles should always be used when removing a flywheel – sometimes flywheels break free with violent force and have been known to fly across a room on unsuspecting mechanics.

A good quality flywheel puller is a precision tool and it is very important to properly lubricate it prior to use. You can achieve good results with an anti-seizing lubricating agent or high-quality grease.
