This tool is designed to safely and easily fit the inner bearing sleeve from a flywheel bearing to the crank.

You just fit the sleeve then tap it into place with this drift and a hammer.

It's best to hold the crank in your hands up against your body rather than stick it in a vice as this will damage the crank.

We do not recommend heating up the inner sleeve as it can affect the hardening of the metal and make the bearing wear.

Fit the inner sleeve to a crank with both parts at the same temperature, use a fine smear of loctite on the crank and bearing when fitting, this way you can tell if if the inner race is going o be tight.
