A flywheel puller is a specialized tool that is designed to remove the flywheel from the engine without damaging it or the engine itself. It consists of a long shaft with a handle on one end and a specialized attachment on the other end that is designed to fit onto the flywheel. The attachment is typically a socket or a wrench that is sized to fit the flywheel's mounting bolts.

To use a flywheel puller, the user first removes any bolts or other fasteners that are holding the flywheel in place. The flywheel puller is then attached to the flywheel, and the user applies pressure to the handle to loosen the flywheel from the engine. Once the flywheel is loose, it can be removed from the engine by pulling it off of the crankshaft.

Flywheel pullers are an essential tool for anyone who is working on engines and needs to remove the flywheel. They are typically made of high-quality materials and are designed to withstand the high forces and torque that are involved in removing flywheels.
