The Unior M12 x 1.25 crankshaft protector screws into the engine crankshaft and protects the transmission shaft when removing the flywheel. It is used when the nuts securing the magnet to the shaft are relatively small. It is especially important for engines with a hollow crankshaft, where lubricant for the end bearings passes through the shaft.
